Croc-licking

[beige_alert]

Via the Mary's Monday Metazoan feature on Pharyngula, we have this National Geographic video of hippopotamuses licking crocodiles. Why? No one knows. What do the crocs think? Not clear if they don't mind or if it's just that hippos are so huge that even a croc can't really do anything about it.

I think it's because crocs have chocolate icing and we've always been too scared to find out.

Wow, that looks odd! I'm really wondering which reason the Hippo has to do that o.O
