110 examples of Echinoderms
Echinoderms are marine animals with peculiar characteristics, which despite being a species of invertebrates have a dermoskeleton. Made up of a series of thorns that make up its body.
These animals are exclusively found in terrestrial waters in the world, whether they are sweet or salty, so their exposure outside of them would cause their subsequent death.
Among the common names given to these marine species are the well-known starfish, as well as urchins, cucumbers and sea lilies.
