Some Characteristics of the Phylum Cnidaria - TI Journals

Abstract: In this paper we have investigated some characteristics of the phylum Cnidaria. Cnidarians form an animal phylum that is more complex than sponges. Cnidarians feed in several ways: predation, absorbing dissolved organic chemicals, filtering food particles out of the water, and obtaining nutrients from symbiotic algae within their cells. Cnidarians live in different ecosystems and have ecological differences. Some cnidarians are parasites.
