Some phyla that contain organisms with endoskeletons include Echinodermata (sea stars, sea urchins), Chordata (vertebrates like humans, birds, fish), and Porifera (sponges). These endoskeletons provide support and protection for the organisms.
Yes, starfish do eat sea urchins. They wrap themselves around the sea urchin and evert their stomach against it to dissolve away the flesh and shell. Eventually when the flesh and shell is dissolved by the starfish stomach acids, the starfish eats the inside of the sea urchin.
Choanoflagellates are a group within kingdom Protista that are thought to be the closest living relatives to sponges. This is based on similarities in cell structure and genetic sequences between choanoflagellates and sponge cells.
The symmetry of the larvae of echinodermata is bilateral.
Sea urchin is a member of Echinoderm family
