PEANUT WORM

Let’s face it – we’re all thinking the same thing. But this is not a penis worm (although they do exist: a whole phylum of penis worms lives in mud in shallower seas). This worm belongs to a different group of seabed dwellers, called ‘sipuncula’. They can retract the front part of their bodies when they’re threatened, making them look more like peanuts. There are male and female peanut worms, which can either reproduce sexually, by releasing sperm and eggs, or asexually, by splitting themselves in half to produce identical clones – handy if they can’t find a mate.
