Fossilized sea sponge.
Nudibranchs are carnivorous predators, typically feeding on various species of sea sponges. Their specific diet depends on the species itself and the environment it inhabits, and many have formed close evolutionary relationships with their prey. Nudibranchs are susceptible to a wide host of marine animals.
