While reading more about this fantastic case of evolution, I suddenly found myself investigating more about crabs. Surely some of you might be thinking at this point, what could be so interesting about crabs aside this particular evolutionary process? Well, I have to admit that previously I have also never felt interested in this kind of creatures. However, after reading about carcinisation, I found it fascinating the fact that although some animals might look like crabs, they are actually not so. In this way, I came to know that what we may call real crabs have actually eight legs, four on each side — certainly, putting aside their pincers. This differs from crab-like crustaceans which, although similar to crabs in appearance, have six legs, three in each side. …
