Megaloremmius leo

It's the world's smallest orangutan! But not, as it turns out, the world's smallest spider.

This beauty is a kind of Huntsman Spider from the rain forests of eastern Madagascar. It can reach something like 5 cm (2 in) long! And that doesn't include the legs. M. leo, like the orangutan, has a real talent for ludicrously long limbs.

Not much is known about M. leo. It's as mysterious as it is orange.
