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.
Sponges defend themselves primarily through chemical means, releasing toxic compounds or deterrent substances to repel predators. They also have a simple structural defense, utilizing their porous bodies to make it difficult for larger predators to consume them. In contrast, cnidarians, such as jellyfish and sea anemones, use specialized cells called cnidocytes that contain stinging structures called nematocysts, allowing them to deliver venom to deter or incapacitate predators. This reliance on stinging cells represents a more active and immediate form of defense compared to the passive chemical defenses of sponges.
