Why are starfish in the echindoerm?
If you look at an echinoderm such as a sea urchin or a sand dollar, you will see that the shell is covered in a pattern (of ambulacral and interambulacral areas) with 5 fold symmetry. A starfish has 5 arms and if you imagine a starfish folding its arms up and over its back until the tips meet, then you will see it begins to resemble a sea urchin, the two are clearly related and have a common ancient ancestor.
What word describes the correct classification of a starfish?
Starfish or sea stars are echinoderms belonging to the class Asteroidea. The names "starfish" and "sea star" essentially refer to members of the Class Asteroidea. However, common usage frequently finds "starfish" and "sea star" also applied to ophiuroids which are correctly referred to as "brittle stars" or "basket stars".
How do sea stars use oxygen?
Sea stars use their water vascular system, which helps to circulate oxygen throughout their body. Oxygen is absorbed directly from the seawater through their tube feet and then transported to the various tissues and organs. This system allows sea stars to obtain the oxygen they need for respiration.

Why do starfish live in saltwater only?
They are not fish despite their name starfish. Starfish are often called sea stars and live only in salt water. Sea water, instead of blood, is actually used to pump nutrients through their bodies via a salt water vascular system. Since they must use salt water to pump nutrients throughout their bodies, they have to live in salt water.
