Is a starfish really a fish?

No. The classic common name is very misleading. Scientists and environmental educators are transitioning their language to seastar when referring to this animal because, well, it is not a fish.

The seastar is in the same family as the sea urchin, sea cucumber, sand image_sci_animal021dollar and a few others that all have these things in common: fivefold radial symmetry, spiny skin and a water based vascular system.

The family is called the “echinoderms” which means spiny skinned.
