Starfish

[GaZZaW]

Saw what i think is a starfish this morning but it only has 4 arms... I dont think its asterina.. any ideas.. thanks. oh its about the size of my thumbnail.

Asterina can have 3, 4, 6 or more arms. They may or may not be a problem, depending on which species it is (I don't think they can be identified to species).

 

[Maritimer]

Asterina rip themselves into pieces to multiply, with each piece (as small as one arm with part of the central disk) growing new arms to become a full star.

So ... yeah.

Asterina.
