This is not a gremlin – it is the world's smallest monkey, the pygmy marmoset (Callithrix pygmaea).
With an adult body length of only 14 to 16 centimetres, and weighing as little as 120 grams, the endangered pygmy marmoset is one of the smallest
primates discovered. They are normally found in the rainforest canopies of South America, however this chap was confiscated after being found inside
the clothes of a Peruvian citizen by police.
This marmoset will now recover at a primate rescue and rehabilitation centre near Santiago, Chile.
