[00:00:00]Everyone my name is Yanktan Rama Namsa.

[00:00:02]I am the faculty of Dispur Nursing Institute. So today I'll be taking a class on the topic that will be the animal kingdom. So this animal kingdom it basically falls under the subject biology. Okay.

[00:00:30]Okay. So first that will be the introduction. So now when you look around, okay, so you will see there are different types of animals. Yes or no?

[00:00:40]So those animals they posess different types of structures and the forms. So therefore it has become very important that you need to do the classification.

[00:00:50]Yes or no? Suppose the reason behind doing the classification is that suppose any new species has been discovered.

[00:00:58]Yes. So now those species which you have discovered newly so that need to be classified. Yes. So now basing on the deaths only there are total 10. Okay. Like in animal kingdom there are total 10 classifications. So which we will be discussing later. So out of that 10 classification only I'm only going to discuss the six and the later I'll be discussing later classification will be done on the next class.

[00:01:47]Okay. So the second is that on what basis we are going to do a classification. Yes. So there are certain features okay that should be kept in mind. So based on that features only those animal kingdom has been classified. So before starting of the basis of the classification you know you need to know what are those classification. So the first classification is that that is what the first one is the pipera. The second one is the okay I'm just going to WRITE IT HERE.

[00:02:21]THE FIRST ONE IS THE ORIFA. The second one is THE Don't worry the notes of this topic will be given to you. So for now you just have a understanding on that. Okay. So there are total 10 classifications. So the first classification is the piper.

[00:03:18]The second one is the nera. The third one is the tenopera. Fourth is platement. Fifth is escalus. Then sixth is the anita. So today I'll be talking only those six classification. Yes.

[00:03:37]Okay. So now we are going to discuss the most important features on which the classification has been done. So the first point that is the first point that is the level of organization. Okay. So this is the one important feature. Okay. Which help us to classify the animal kingdom. So now then the level of the organization. Yes.

[00:04:13]So now this level of organization it has been also further divided into three. So those are number one is THE OKAY. So I have told uh I have told as a tree. Okay. So this organ level or the organ system you can write as a slash.

[00:04:58]Okay. So now this level of organization first one is the cellular level. So now when I'm talking about the cellular level that defines that over here okay in cellular level what is happening is there like all the cells they are has been arranged in a loosely formed. Okay.

[00:05:14]So the by name understood you need to understand that in cellular level the all the cells of that particular organisms has been arranged in a loosely and the best example that is the sponges. Okay, sponges is the best example when we are talking about the cellular level. Okay, then comes with the tissue level. So in tissue level what is happening is that now when all the cells they have been compact together and formed as a complex then that cellular level will converted to the tissue level. Then third one is the organ level. So now when all the tissue level they can combine together so they're going to form as a organ level and which they will function as a specific function. Then organ system there is nothing but when all the organ levels they combine together so they perform they will become one system and function one particular physiological function. So that is known as the organ system. So based on this that is the first feature.

[00:06:27]The second feature is that THE those are very easy. So the second feature that is the symmetry. Okay. So symmetry it has also been further classified into okay so now when I'm talking about the asymmetry suppose if any plane you are cutting okay then they are not going to cut into the two equal halves. So that time that is known as the a symmetry.

[00:07:14]Then radial symmetry.

[00:07:16]So in radial symmetry suppose you consider this as a circle. So in radial symmetry if any plane is passing through the center then they are converted into two equal parts. Okay. Suppose if you're making any plane from the center so they're going to divide into two equal parts like this. So if if you're cutting the any plan from this side then they're cutting into two equal parts. So such type of is known as the radial symmetry.

[00:07:40]So in the bilateral symmetry means if they are cutting okay in bilateral symmetry any plane passing okay divides into left and the right okay equally left and right. So that is known as the bilateral symmetry.

[00:08:14]So now that is another feature that is the DIGESTIVE SYSTEM.

[00:08:30]HEAT.

[00:08:45]HEAT.

[00:09:05]OKAY. So now when we are talking about the digestive system, so now this digestive system has also further divided into two that is the complete and the incomplete. So what is happening in the complete? So in complete what you need to see is that okay so we were discussing about the digestive system. Yes. So now this digestive system has been further classified into two that is the complete and the incomplete. So now when I'm talking about the incomplete digestive system, so there is only one opening.

[00:09:33]Okay. So that opening will act both as a anus and as well as for the mouth and the another one is the complete digestive system. So in the complete digestive system there are two openings.

[00:09:43]So one is for the mouth and one is for the anus. So this is all about the digestive system. So now next comes that with the another features for the classification that is the Okay. So the next feature that is the circulatory system. So this circulatory system has also been classified into two. One is the open and another one is the close. Okay. So now what is happening in the open circulatory system is that like all the blood okay that has been formed from the heart. Yes. Then all our organs that have been bath in that uh blood. So that is known as the open. So what is happening in the clause is that the blood okay that has been spread to our parts of the body with the help of the veins arteries or the capillaries.

[00:11:01]Yes. So if our blood okay that has been spread in our body with the help of the arteries veence and the capillaries so that time we have the closed circulatory system. Okay. So now coming on to the next features that is the on the basis of the germ layer.

[00:11:53]Okay. So now when we are talking on the basis of the germ layers so that has been also divided into two that is the diplo plastic and another one is the tripoplastic. So uh so those features whatever I'm explaining over here. So now when we will be talking about the main classification so over there I'm just going to discuss what is diploastlastic what is triplastic I will just say like this uh like film condense diplopastic another film contains the tripoplastic so by looking at the name only you will be able to understand like what does the diploastlastic and the triple plastic means okay so now when I'm talking about the diploastlastic means over here how many layers are there so there will be only two layers okay so those two layers will be Yes. So there will be two layers of germ layers that is the ectodorm and another one will be the endodm.

[00:12:47]So now when I'm talking about the so I have told that has been divided into two that is the ectodorm and another one is the endodm. So now when I'm talking about the ectodorm we all know that ectodorm it is the outermost layer. Yes or no? and the endodm it is the innermost layer. So now when I'm talking about the diplo plastic mean that time they will have the ectodomor and the endodm but there is also one middle layer which is known as the we all know that middle layer of the gum layer is known as the meodm but meodm is not been present in this developlastic. Okay. But so as I have told there is also a middle layer in the germ layer which is also known as the mesodorm. Now so this meodorm it has been absent in this dipoplastic. But you need to remember one thing that meodorm meodorm. So this dom it is only been said when the cells has been completely differentiated.

[00:13:53]Okay. The term is known as meodm. What if those cells which is present in the middle layer but if they are not differentiated properly then that is known as meoglia. So now this meoglia is present in the diploastic. OKAY.

[00:14:13]YES. So you're understanding. So now when I'm talking about the diploastic so over here two germ layers are present that is the ectoderm and the endodorm.

[00:14:22]Yes. But there is also one undifferiated middle layer which is known as the mesoglea. Yes. So now moving on to the next that is the tripoplastic. So the name itself says triple mean three layers of the germ. So first one is the ecto then comes with the messoderm then comes with this endoderm.

[00:14:43]Okay. So this is the another features which we have done.

[00:15:00]Okay. So now we were talking about the body cavity here. So this known as the ailment, pseudocyto and the summit. So now when I'm talking about the aselum means I have taugh that when there is absence of the body cavity. So now when I'm talking about the pseudocam so as we all know the pseudoms yes or no. So I'll just uh do a diagram so that you can understand in a better way.

[00:15:48]So let's see.

[00:16:00]Okay, I'm just drawing this diagram in a rough manner.

[00:16:22]Okay. So this is the germ layer. Okay.

[00:16:25]So in this germ layer you'll see that this is the what ectodorm and this is the meodorm.

[00:16:49]Okay. So since now we are talking on the basis of the body cavity. Yes or no? So this is known as the ectom and this is known as the mesodorm and this one is known as the body cavity. Okay. So now when I'm talking about the pedocament.

[00:17:01]So in cedamament you will see that this messm is present but they are all are present in a pouch in a skater pouch. So when a meodorm is present in a scotter pouch then that is known as the pseudo silomate. Okay.

[00:17:18]Okay. The features which we have discussed earlier that was related on the body cavity. So again I'm going to tell that is first one was oursel.

[00:17:27]So now when I'm talking about the cylate means when there is a presence of the body cavity. Yes. But in the pedo the meodone is present but they are present in the scatter page. So that term is known as the pseudocate. The last that is the aselomate. So in the aselomid means body cavity is absent or in certain animals you won't see any kind of body cavity.

[00:17:49]So that time it is known as the aselomid. Okay. So now again comes with the another feature that is THE SEGMENTATION.

[00:18:03]OKAY. So now when I'm talking about the segmentation males now when you cut or dissect any animals both the internally or the externally they will have the segments. So that is known as the segmentation. And the most important example in segmentation that we can see in our day-to-day life is the art form. Okay. So those are the features or the most important fundamental features which help us to do the classification of the animals. So now moving on to the next that is we are going to discuss our main classification or which is also known as the fila.

[00:18:40]Okay. So the first classification that will be the we're talking about the first filer that is the porifera. So the first point that you need to keep in this thing is that okay so this piper okay they are also known as the sponges. So you should not get confused. Okay. So sponges are also known as the porifera or pipera. The other name of pipera is also known as the sponges. Then second point IS OKAY. The second point is they are mostly found in the marin. Okay. They're mostly found in the meant and there what is the level that is their asymmetrical that means when any plane passing through the center it is not going to divide into two equal halves so that is why it is known as the asymmetrical so which I have discussed in the previous thing the last that is Oh seen is that those are the sponges or they are also known as the sponges. They are basically found in the marine and it is asymmetrical in the nature. So now when we are talking on the basis of the level of the organization so they are uh they are also classified into the cellular that means all the cells that has been aggregate in a loose form.

[00:20:22]Okay. So the another thing that we will see over here in the pipera that with the two terms that is the Okay. So in pipera you will see this term that is the osteium. So now when I'm talking about the osteium so you need to remember that in osteium is from where the water enters. So as from the beginning only I have told that when we are talking about the orifera means they are having the pores yes or no. So osteium means it is a small small.

[00:21:21]Okay. So those are the small small or the minute pores. So which is known as the oium. So from where the water is going to enter and the spongy cell it is a body cavity. Okay. or the canal cavity which is found in this one porifera. The another one is the osculum. So now from that body cavity the water needs to come out. So that they are going to come out from that p which is known as the osculum. Okay. So the another point in this pipera that you need to remember is that they are uh this one bisexual or we can say that they are also known as a harmas means their sexes are not different. Now moving on to the next that is the exam.

[00:22:12]Okay. The example which is the example for the pipella that is the cyclone and the sponge area. Okay. So again one more point which I have forgotten that is the okay the another point that is the spicules. So spicules means those their eskeeleton okay their skeleton has been covered with spicules. So this is all about the important features which is present in the orifera. The first point that is the it is asymmetrical. The level of the organization is in the form of the cellular. Then they are basically found in the meine. They are also known as the sponges. So the another point is this osteium from where the water enters.

[00:23:04]Sponges it is the canal cavity or the body cavity. Oculum from where the vortex comes out. Then those they are also covered by the skeleton which is known as the spicules. and the they are their sexes are in the bisexual or also known as the hermaphrodite then the example is the second and the sponges sila.

[00:23:26]So now we'll be talking about the another fil or the classification which is known as THE NIGERIA. OKAY. So in Nigeria what is the first point is that there are basically marine it is an aquatic in nature and second point is that they are also a free swimming. Okay the second point that is that they also posess one specialized cells which is known as the neato sittes. So this neato sites you need to remember that this specialized cells is only present in the nidaria.

[00:24:07]Then in the third point what is you need to see is that they are radial there are radial symmetry. Okay. So in this radius symmetry means I have taugh that if any plane is crossing from the center it is going to divide in two equal halves. Diploastic in nature that means two layers are present that is the ectodom and the endodm. Then it is the level of the organization over here it will be that they will have the tissue level of organization and the example of this nera that is the lordina and another one is the penetula.

[00:24:59]Okay. So this is all about the Nigeria.

[00:25:04]Okay. So this was all about the Nigeria.

[00:25:07]Okay. So in this Nigeria there was also there is also two important forms which is also known as THE pop and the medusa. Okay. So those are the two important forms which is found in the Nigerian pop. they are in the cylindrical and this one is in the form of the umbrella. Okay. So now when we are talking about the sexual. So now this pul they were going to convert into the medusa in the form of the asexual.

[00:25:41]And now this medusa they will also converted to form in this pulp in the form of the sexual.

[00:25:49]Okay. And example I have discussed. So this is all about the nigeria.

[00:25:57]Okay. So the next classification of the filer that will be about THE TENOPHORA. So now this genophora they are also exclusively marine they are also radially asym radially symmetrical sorry then they are also in developlastic in nature and the level of organization is in the tissue but they are known as the com jalis and the total number of com jalis that is present in the tenopera that is the eight okay so the another feature is at.

[00:26:44]Okay. The another features which is present in the tenopera that is the luminescence. So luminescence means any organisms which emits light. Okay. So that is known as the luminisms and the example that is there is the so there is also one important features which is present in the tenopera that is THE that is known as the bioluminance. So a bioluminance means any organisms which emits light. Okay. And the example is the tenoper.

[00:27:20]So this is all about the tenino fera.

[00:27:26]Now moving on to the next that is the okay. So now we'll be discussing about the plate hormentors. Okay. So now this plate helmets they are also known as the round worms.

[00:27:52]Okay. So now we'll be talking about the plate hormetals. So now this platey helmets okay they are also known as the flat worms. So now the reason behind considering this plate helmets as flatworms is that they have the dorso and the vententral. Yes or no? So this dorso and the ventral side of the body are flattened. So due to which they are also known as the flat worms. Okay. So now second feature that we'll be discussing is that there ARE OKAY. So now another features that is the they are bilateral symmetry that means when you are cutting any plant so they are going to divide into right and the left then they are having the organ level of this one organization then they are also known as the asulum made that means they are not having any kind of body cavity okay and THE flame cells okay so this flam cells it is usually seen in the plate hormones.

[00:29:10]So now the importance of having the flame cells is that they help in the osmo regulation and the escalation of the body and the example of this plate helmet is the tab one which is also known as the tenia. Okay. So now we'll be moving on to the next column that will be THE okay so now we'll be talking about the escalus. Okay. So now in as methyl the first point is that they are usually found in the aquatic and as well as in the terrestrial region. The second point is that they are second point they are also known as the round worms and they are bilateral symmetrical. They are also triplastic in nature. The third one is in level of the organization they have the organ system.

[00:30:01]So now when we are talking about in the frame of the body cavity there are pseudoate. Okay.

[00:30:10]So over here what you're going to see is that uh their elementary canal is complete. Okay. With the the important features okay which is present in the escalator that is the muscular fairings. Yes. Then next point is this both the sexes are different for the males and the female. Okay. So over here this female okay they are longer as compared to the male. And the two important examples which falls under ascal methods that is the okay as underia those are the two examples which falls under the escalant.

[00:31:05]Oh yeah.

[00:31:08]So the last film for the today class that will be my anal. Okay. So in this anal they are also found in the aquatic as well as in the terrestal. Second one is there are bilateral symmetrical then it is also in the triplastic. Yes. So in the level of the organization they have the organ system. So the important features. Okay.

[00:31:39]Which you will seen is that they are this any leader they are in the presence of the segmentation. Yes.

[00:32:13]So this is the diagram which I have drawn for an outworm because the best example for the anita that is the outworm. Okay. So now this thing which you are seeing so that is known as the metameism. Okay. This segment. Okay. So this is all in the form of the segment.

[00:32:29]So each segment is known as the metameism and this in the lateral side you can see those appendages and all. So that is known as the okay. So this lateral appendages which you can see here that is known as the parapodia. So the importance of having parapodia is that if they are found in the aquatic reason so it will help them in the swimming. Okay. Then Nephimma it is an excretary organ which is found in the anal which helps in for the excretion and the example for this one is THE and the example is known as the feritima. Okay. So this feritima in the common name it is also known as the outworm. discussing about the last okay filer that will be OUR any leader. So now this any leader they are usually found in the aquatic as well as in the terrestrial region. They are bilaterally symmetrical they are triplastic in their nature and in the level of the organization they are the organ system. Okay.

[00:33:52]Then the other thing is that so this NA leader. Okay. So they are in the form of this segments. So those are known as metameirs.

[00:34:28]Okay. So those segments are known as the metame and in the lateral side you can see some like hanging like structures and all these things. So they are known as the parapodia which houses them in the swimming. Okay. Then the another term that is the okay the another term that is the nefridia. So in the nephidia what is happening is that it is an excratory system okay which is found in the anal and it helps for the excretion.

[00:35:17]Okay. Okay. So I have told that is THE okay so when we are talking about the nefridia so it is an as exc as okay which is found in the analids and it is found it is used for the excretion and all those things and the example is the feritima okay so this feritima it is also known as about the artwork. So this was all about my today's topic and thank you so much for your cooperation.
