Golden lion tamarin  (Leontopithecus rosalia)

The golden lion tamarin, one of the world's most striking mammals, is so-called because of the beautiful mane of silky golden hair that frames its face (5). The fur is a lustrous golden colour, apart from the tail and forepaws, which may be brown or black (6). The digits are long and delicate with claw-like nails, which are perfectly adapted to forage for small prey items (7). Males are typically larger than females (6), although there is some argument that there is simply seasonal variation in weight (2), but otherwise there are no major differences between the sexes (5).
