Fun fact: Through a process of convergent evolution called carcinisation, crustaceans have evolved into crabs several times.

It's also a highly debated theory.

Is it really? I figured it was just another textbook example of convergent evolution, as that is where I learned about it. I know my comment should have said 'evolved crab-like bodies' instead, as they'd still be genetically distinct, and not taxonomically true crabs. Now I feel like I have to read up on what the exact nature of the debate is.

Why not Zoidberg?

Yet another unrealistic standard set for men

The true meaning of carcinization, revealed

can normal animals in nature get fat? like a particularly lazy tiger or something

Sure, provided the food is available and doesn't cost too many calories to obtain. The real problem lies in the fact that most fat animals get hunted by other, faster, hungrier carnivores. Sure you can get fat in nature but it's a hell of a feat to stay fat (and alive) in nature.
