Lutrinae

Otters: A study of the recent Lutrinae. William Cowers and Sons, Ltd., London.

Argentina is the country with the highest diversity of Lutrinae species, with four of the 16 species of the world.

Of these 65 clades, we eliminated 33 because their members had large body size or were primates (Loridae, Galagonidae, Cercopithecinae, Colobinae, Hominidae, Canidae, Acinonychinae, Felinae, Pantherinae, Herpestinae, Hyaeninae, Protelinae, Lutrinae, Mellivorinac, Mustelinae, Nandinimae, Viverrinae, Elephantidae, Rhinocerotidae, Orycteropodidae, Aepycerotinae, Alcelaphinae, Antilopinae, Bovinae, Cephalophinae, Hippotraginae, Reduncinae, Phacochoerinae, Suinae, Hippopotamidae, Tragulidae, Giraffidae, Manidae).

Otters are placed in the sub-family Lutrinae. There are 13 species of otters distributed all over the world except for Australia, Antarctica and some oceanic islands (Mason and Macdonald, 1986).
