Watch out, there are many crab-looking things that aren't really crabs!
There is a process knows as carcinazation, where convergent evolution makes crustaceans take forms very similar to crabs. The best studied example is the King Crab. Also known as Stone Crab, this delicious creature it is not a real crab at all! Just count its legs, it isn't even a decapod! Unbelievable!
Actually, it is closely related to the Hermit Crab (Cobito), which in turn isn't a real crab either! Both the King Crab and the Hermit Crab are asymmetric, while real crabs are symmetric.
Amazing!
