The pygmy sloth is one of the new additions to a list of weird and wonderful looking mammals that are endangered.
The EDGE list - that stands for evolutionarily distinct and globally endangered - now includes the black and white ruffed lemur too.
Conservationists are worried that endangered animals like the Chinese pangolin get overlooked because they're not as cute as other species under threat.
"EDGE mammals are one of a kind and they represent the true diversity of life on Earth," said Carly Waterman from EDGE, who's hoping to help mammals like this Malayan tapir.
It's hoped that bringing attention to these unusual looking animals - like this rondo dwarf galago - will attract money and trigger action to help to save them from extinction.
