Holy Osculating Owl Monkeys, Batman!

Given the various wtf posts about tarsiers, and marmosets, and glowing rhesus macaques, here's one about a genus of primates you might not have heard about before.

Douroucoulis, small South American primates also known as Night Monkeys, & Owl Monkeys, of the genus Aotus. Aotus means earless, and their ears are indeed quite small. On the other hand, they do have large eyes, because they're the world's only nocturnal monkeys. There are plenty of nocturnal prosimians out there - tarsiers, galagos, aye-ayes, lorises, and so on, but only the Aotidae have gone back to nocturnalism from amongst the true monkeys. They're so specialised to feed and move at night they've lost all their colour vision.

Devil's Coach Horse Beetle - Facts and Superstition

Ok, this time around I will NOT be supplying you with a chainmail which I was stupid enough to post here. I am trying to redeem myself with some information on one of my native Britain's largest of all beetles and extremely interesting too. I really got interested in them after I found on the floor of our living room, scuttling about. Enjoy!

The devil's coach-horse beetle (Ocypus olens) is a very common and widespread European beetle, belonging to the large family of the Rove beetles (Staphylinidae). It was originally named Staphylinus olens in 1764, and some authors and biologists still use this older name. The species has also been introduced to the Americas and parts of Australasia.

This black beetle usually shelters during the day under stones, logs or leaf litter. It is most often seen in forests, parks and gardens between April and October.
