A bird is NOT an echinoderm because they dont live in salt water
The Sunflower Starfish (of Sea Star) is none of the four mentioned in the question. It is an echinoderm, a marine invertebret having a central disc and many arms.
Jellyfish are cnidarians.
um, no. a jellyfish is far from a bird. it is an animal that lives in the oceanic waters you can read about them and look at pictures here... http://en.wikipedia.org/wiki/Jellyfish
There are very few Australian animals beginning with 'i'. There are no iguanas native to Australia, but there are a couple of Australian animals beginning with 'i'.irukandji (a deadly jellyfish)ibis (a wading bird)
The Green Turtles use they're bird like beak to attack soft prey such as jellyfish.
Both birds and sharks are vertebrates whereas starfish are not.
I think it's a carnivore. It eats things like little crabs or something ;-)
Bird can fly while the other animals cannot.
Shark, shrimp and sheep are animals. Additional animals include shoebill (bird) and shearwater (bird).
a bird a bird
not either. It is not a mammal... not a bird... not an insect... not a reptile... not a amphibian... not even a fish... it is classified in the group called echinoderms! Echinoderms are marine animals that live in the ocean. Common echinoderms include the sea star, sea urchin, sand dollar and sea cucumber. Most echinoderms have arms or spines that radiate from the center of their body. The central body contains their organs, and their mouth for feeding. Sea stars, commonly known as the starfish, have 5 or more arms attached to their body. On the bottom of the Starfish are small tube feet to help with movement and feeding. The starfish's mouth is underneath, and is capable of eating other sea life such as clams and mussels. Another type of echinoderm is the sea urchin. Sea urchins have many spines connected to their body. These spines help to protect them from predators.
