What does echinoderm mean in science terms?
Definition of echinoderm
: any of a phylum (Echinodermata) of radially symmetrical coelomate marine animals including the starfishes, sea urchins, and related forms.
What do cnidarians eat?
Most cnidarians prey on organisms ranging in size from plankton to animals several times larger than themselves, but many obtain much of their nutrition from dinoflagellates, and a few are parasites. Many are preyed on by other animals including starfish, sea slugs, fish, turtles, and even other cnidarians.
Are sponges cnidarians?
Sponges are also called sea sponges. Cnidarians include jellyfish and corals. Invertebrates in these phyla have existed virtually unchanged for hundreds of millions of years. This shows that they are well adapted for their habitats.

What coral is phylum?

Why cnidarians are considered important?
They are major constituents of coral reefs. Cnidarians are integral parts of the marine ecosystem where they may engage in symbiotic relationships with other organisms and where their predatory activities contribute to the delicate balance of the oceanic food chain.
