The Golden Lion Tamarin (Leontopithecus rosalia) also known as Golden Marmoset, is a small New World monkey of the family Cebidae. Native to the Atlantic coastal forests of Brazil, the Golden Lion Tamarin is an endangered species with an estimated wild population of "more than 1,000 individuals" and a captive population maintained at approximately 490 individuals.
If these guys don't remind you of "Gizmo" from Gremlins, I don't know if anything will. A.J. Haverkamp captured these priceless marmoset moments at the Artis Zoo in Amsterdam just the other day. There are actually two babies in that fluffy mound, can you make out both? Thanks for the incredible pics A.J.!
Already the smallest monkey in the world, these baby marmosets are absolutely itty-bitty. Baby pygmy marmosets can currently only be spotted by very keen-eyed visitors to Lakes Aquarium in the UK. They appear as furry lumps on the backs of their parents – most often their father.
These little babies only weight half an ounce!
This last picture actually comes from the Everland Zoo and Theme Park in South Korea, but should give you an idea of scale.
