What I love the most about skulls is their “in your face” attitude
Vampire bats are really good friends to have… if you like to drink blood, that is.
If a vampire bat doesn’t feast on blood for two days, it will probably starve to death. However, they display reciprocal altruism- other bats will regurgitate the blood that they’ve managed to find during the night and feed the starving bats in their roost until they are okay.
…well, I find that kind of cute…
