What happens when a crab eats methane?

Seriously.  Did you think that was even possible?  Well, this fascinating video shows the of a methane seep in the deep ocean (where it's both cold and the pressure is high), this hapless crab encounters the methane bubbles and tries to eat them, his mouth gets frozen shut.

Seriously. Almost like licking a metal stair railing on a very cold day; this crab would  very stupid if it was possible for a crab to feel emotions.

We can just laugh.
