Oooh, check out this freaky creature. He might look like something out of a horror film, but this is actually a real-life ghost bat. He's from the vampire bat family!
Scary or sweet? This is the Brazilian bare-faced tamarin monkey. All of these creatures feature in the ARKive project - which collects photos of endangered animals.
This startled-looking thing is the predatory bush cricket. By showing us what these endangered animals look like, and telling us how they live, ARKive hopes to help preserve them.
This cutie is a Horsfield's tarsier - if our eyes were the same proportion as this they'd be as big as apples! So far, ARKive has profiled 6,000 weird and wonderful plants and animals.
By the end of 2010, ARKive wants to have 17,000 images of the world's most endangered plants and animals.
By doing this, they hope to help save many of these creatures - like this Saiga antelope - from dying out.
