#4 - Tarsier

Found in the East Indies and the Philippines. They are about the size of a rat with thick, light-brown fur, very large eyes, and long feet and hands. They are nocturnal, arboreal, and eat insects and lizards.

All ore okay.

Well done Izzi.

#29 = Indri, from Madagascar, an endangered animal.

15- Owl monkey

Also known as a dourocoli, this nocturnal South American primate has huge eyes, much like a bushbaby.

Two more right answers.

A truly beautiful species with ginger-red fur, the patas monkey lives in troops on the plains of Africa.

#30 Leaf monkey, aka the Silvered Langur, taking its name from the grey adult fur colouring

#28 - Dwarf Galago

Three more solved.

38 seems to be the same as 30.

#10 Bushbaby

#27 Cacajao - the Bald uakari, named because of its hairless face.

30 was leaf monkey, so is 38 bear monkey???

Three more right aanswers: 10 = bushbaby, 27 = cacajao, and 38 = bear monkey.

Note: you may now answer more than 1 at a time.

Both male and female Emperor tamarins have huge white moustaches, while the Cotton-top tamarin has a mass of fluffy white fur on its crown. Dad does all the babysitting and only takes a breather when it's feeding time for the youngsters.

Both answers are right.
