Starfish belong to the Echinodermata phylum, meaning 'spiny-bodied animals,' and live exclusively in marine environments. Despite lacking a brain, they possess a unique water vascular system that enables movement, feeding, and respiration. Their mouth is located on the lower side while the anus is on the upper side. A remarkable biological transformation occurs during development: echinoderm larvae are bilateral (with left and right symmetry), but adults become radially symmetrical. Common examples include starfish, sea urchins, and sea cucumbers.

Starfish Secret You Didnβt Know π€―Added:
Did you know? Starfish don't have a brain, but still move and eat like pros.
They belong to a group called Echinodermata, which literally means spiny-bodied animals. These creatures live only in the ocean and have a unique feature called the water vascular system. This system helps them move, catch food, and even breathe. Another crazy fact, their mouth is on the bottom and the anus is on the top. And here's the twist, baby echinoderms are bilateral, but adults become radially symmetrical. Examples include starfish, sea urchins, and sea cucumbers. Nature is wild, right?
