As a summary of this discovery, i can say that the sand dollar larvae clones itself when a predator is near to it, the scientist explains in the article that the clones are smaller than the original larvae and thanks to that they have a chance to survive hiding themselves from the predator, though some investigators think that a tiny size eventually can be dangerous for a larvae in the sea, where for many species being bigger helps scare off predators, the researchers don’t know yet if this is true for sand dollars, only they could prove the larvae clone itself in front of the danger and so far nobody has seen a response like that.
