[00:00:00]As the world's only strictly sea grass eating marine mammal, they have one MO.

[00:00:06]To graze their cares away.

[00:00:09]These hungry dugongs are semi-nomadic and will travel long distances in search of the very finest sea grass buffets. In Australia, they've been clocked traveling over 600 km.

[00:00:23]That would be about the same distance as heading to Paris for a meal if you lived in London.

[00:00:30]Then again, can you blame anyone for wanting a French pastry over boiled potatoes?

[00:00:36]While dugongs are known for being giants, their brains only weigh a mere fraction of their body weight. About 0.1% of it.

[00:00:46]At 300 g, it's only the size of about two small apples and known for being silky smooth.

[00:00:54]What is a smooth brain, you ask? Well, it's one that doesn't look all curled and folded like you might usually picture.

[00:01:03]The brains of both dugongs and manatees have evolved to these smoother shapes because of their non-predatory and slow-moving lifestyles. Unlike other marine mammals that have more complex folds in their brains, like dolphins and whales, helping them with hunting and sensory processes like echolocation.

[00:01:24]But don't let size fool you. Dugongs are known to have good memories and can even log prime feeding areas to come back to them after traveling. [music] Kind of like dropping a pin after visiting your favorite restaurant.

[00:01:39]Smart.
