Q: whats the difference between echinodermata and echinoderms? are they the same thing ?

A: http://tolweb.org/EchinodermataEchinoderms (Phylum Echinodermata) are a phylum of marine animals. Echinoderms are found at every ocean depth, from the intertidal zone to the abyssal zone. Aside from the problematic Arkarua, the first definitive members of the phylum appeared near the start of the Cambrian period.The phylum contains about 7,000 living species, making it the second-largest grouping of deuterostomes, after the chordates; they are also the largest phylum that has no freshwater or terrestrial representatives.

What are the enemies of Echinodermata?

Q: I am doing homework and so I need help. I have less than a week left to do my homework so can you please help.

A: Echinoderm larvae are eaten by plenty of zooplankton, crustaceans, fish, filter feeders, coral, pretty much every predator of the right size in the ocean.When they grow up, echinoderms are armored and so are less vulnerable. Still, you’ll find shorebirds eating starfish, crabs eating several echinoderms. I’d bet that even octopus would eat small echinoderms, and fish and sea turtles would eat sea cucumbers….and of course, people eat sea urchins. I remember my freshman biology course’s trip to the seashore. The professor broke one open, and took a bite.

Which one of the following statements about the phylum Echinodermata is false?

Q: a. Many species possess an internal calcareous skeleton and spiny dermal projections. b. Larval forms show evidence of bilateral symmetry, which is mostly lost in the adult form. c. Echinoderms have true radial symmetry as adults. d. All possess a water vascular system, which permits movements via tube feet. e. One of the classes in this phylum is Asteroidea—the sea stars.

A: The only fault I can find in all the statements above is in C.Echinoderms are radially symmetrical, but their symmetry is called pentaradial, not true radial. This is because it can be symmetrical when cut through in the middle of any one of it’s FIVE feet.
