Another problem is that they are voracious predators. From Alaska to California, Sunflower Starfish can be seen rushing, no, hurtling at speeds of a metre per minute on their 15,000 tube feet. Clearly, prey doesn't stand a chance with this kind of blinding pace. Certainly not when prey consists of sea urchins, clams, snails and other starfish. Or indeed dead cephalopods. The mouth is at the centre of the tube feet and can be opened wide to swallow food. If it's too big for that, they can also do that disgusting thing where they spit out their own stomach and start digesting stuff outside of their body before swallowing. I wish they would try out chewing instead, I really do.

After this, they settle down on the ocean floor as tiny little starfish with 5 arms. Pff, 5 arms? 5? Bit normal, innit? Of course it is. So the other 19 will have to come as they grow and stop being quite so tiny. Eventually, they will clear their path ahead using nothing but the power of menace and the inspiration of fear, just like their parents!
