Starfish(海星) are not real fish at all. They are animals in the sea.

A starfish looks like a star. Most of them have five arms. Some have even more. At the tip of each arm is an eye. A starfish has as many eyes as it has arms!

In many ways, this animal is different. If an arm is lost, it can grow a new one. If a starfish is cut in two, each piece will grow into a whole new starfish!

Starfish are not good to eat. Dry ones are very pretty. When children find them beside the sea, they like to take them home.

根据短文内容判断正(A)误(B)。

小题1:Starfish are not fish.

小题2:The whole passage (短文) is about fish.

小题3:Starfish are good to eat.

小题4:A starfish looks like a star.
