The name lemur is Latin for 'spirits of the night.'

Lemurs bask in the sunlight by sitting upright facing the sun with their arms outstretched.

Blue-eyed lemurs are one of the two (non-human) primates to have truly blue eyes.

Ring-tailed lemurs rub stinky secretions into their tails and wave them at rivals.

The pygmy mouse lemur is the smallest primate in the world. Not counting the tail, its head and body are less than 6 cm [2.5 inches] long.

Sifaka lemurs spend most of their time in the trees, but don't get around in the same way that other lemurs do. Sifakas remain upright, and they leap quickly from tree to tree by jumping with their powerful hind legs. In this way, they clear distances of over 9 m [30 ft]. They can also move quickly on the ground, which they do using a two-legged sideways hop.

Local Malagasy people named Sifakas for the unique call they send echoing through Madagascar's forests, which sounds like shif-auk.

Coquerel's Sifaka shown in the two images below.

See the video at the beginning of the part for leaping Sifakas.

Lemurs have two tongues! They use their main tongue to help reach inside flowers to lick the tasty nectar as well as for normal eating assistance. Under the main tongue sits a smaller tongue made of stiffer cartilage. This is the grooming tongue, used as they clean other lemurs. They groom each other by picking through the fur to remove dead skin and small insects. The stiff tongue reaches through the lemur's hair to the skin and helps push out unwanted items. While insects collected during grooming might be desirable, another lemur's hair isn't. They also use their stiff second tongue to help remove those hairs.

A bit off topic but...
Madagascar, their native habitat, is the fourth largest island on earth.

A/n: who's seen a Kratt brother's TV show? Kratt's Creatures and the Wild Kratts are my personal favorites XD. Looking up Sifaka facts eventually led to me listening to the Zoboomafoo theme song. It's catchy lol.

I'm open to requests! It can be a specific species or a group of animals. Leave the request(s) in the comment section below, or message me some other way and I'll do a part for you, if the animal hasn't already been done. If not, I should have it up within the week. :)
