I found this seaweed decorator crab while I was beachcombing ... at the Trigg Beach I think. I added the green and orange battery to give you an idea of it's small size. And on the left of it, I put a small bunch of seaweed to show how similar they look.
The upper side of the same crab. Doesn't it just look like a small bunch of seaweed!
Apparently, this amazing animal can pick and plant seaweeds on its back, which is covered by hook-like hairs. Over time, it's back gets coated in seaweeds and this disguises the animal protecting it from enemies. And it is not all bad for the seaweed; the plant actually grows.
So how do you like growing some seaweeds on your back?
