the special characteristic of starfish are they have an Exoskeleton and Radial symmetry
seeing as starfish live in most, if not all levels of the sea, any plant you can think of as being a marine plant lives where starfish live. Examples: phytoplankton, red algaes, green algaes, brown algaes, sea grasses.
Dead Starfish change colour when they die, if you have seen a Starfish in a certain colour, and then it's colour changes it has died. If you are not sure if a certain Starfish is dead and have never seen it in another colour, then it's going to be pretty hard to find out if it's dead or not, but most Starfish are red.
