The question which would win in a fight between a crocodile and a shark has recently been much contested.
Assuming the crocodile has had ample basking time and they are a size-for-size match, I'm backing the croc. Though I don't know how they fare in open water.
Sharks are still cooler, though.
I didn't draw this for IF originally, but for a friend with whom sharks have been much discussed, and which recently have featured the shark/croc dilemma.
It just so happens that the topic 'Jump' rather fits the bill as well.
But is it really jumping if a creature has no legs?
