Interesting animal oddities, Post interesting facts about animals

Indeed, when water turns solid it increases in size by about ~10%, and we're made up of quite alot of water. This basically means that freezing ourselves shreds our organism due to huge particles of ice within us.

Anyways, I'm not sure how accurate this is, but I've heard that Polar Bears are the only living beings that can choose not to shit (i.e. they re-digest the food).

I've heard that as well, although I'm doubtful as to its veracity (not that Polar Bears can't do it, just that no other organism can)

On the subject of faecal matter, sloths only go for a shit once a month, and it's the most perilous time of their existence as it involves leaving the trees to shit on the ground.

Also, sloths are, somewhat surprisingly, really rather good swimmers, swimming much faster than they do anything else (since they cannot jump, it's the only way to travel from tree to tree during the floods.) In fact, they are some of the best swimmers amongst all tree-dwelling animals. However, they can't swim for very long before they become waterlogged because of their thick fur and drown. One of the ironies of life, right there.
