By Phil Myers
The raccoon family includes 18 species in 6 genera. We follow Wilson and Reeder (1993) in placing red pandas, Ailurus , in the Ursidae rather than in this family. Thus restricted, the Procyonidae is restricted to the New World, from southern Canada to northern Argentina. Procyonids can be found in a wide variety of habitats, including desert, northern forests, tropical rainforest, and wetlands.
Procyonids are generally small to medium-sized animals, ranging from slightly less than 1 kg to over 20 kg in weight. Some species have slender bodies, while others are stocky. All have medium or long tails. The pelage is gray or brown, sometimes with contrasting markings on the face and light and dark rings around the tail. Most species have relatively short, broad faces; and short but erect ears, which may be rounded or pointed. Forefeet and hindfeet have 5 digits, and procyonids are plantigrade , often walking with a bear-like shuffle. The claws are short and curved. In some species they can be partially retracted. The tail of of species, the kinkajou, is prehensile, and that of coatis is very mobile and is used for balancing during climbing. Males have a well-developed, bilobed baculum.
Procyonid
skulls
have relatively short
rostrums
(shorter than
canids
, longer than
felids
). They lack
alisphenoid canals
, but they have well-developed
paroccipital processes
. Their
incisors
are unspecialized, and their
canines
are moderately long and ovate (not round) in cross section. The
molars
are wide and at least somewhat
bunodont
. Most species lack
secodont
carnassials
. The
dental formula
is 3/3, 1/1, 3-4/3-4, 2/2-3 = 36-42.
Procyonids are omnivorous. They consume both plant and animal material, including small mammals and birds. Some species are social, living in family groups or bands containing a number of families. Others are solitary. All species are to some degree arboreal, often seeking refuge in the trees when pursued by predators. Most are nocturnal, often denning in hollow trees during the day.
The Procyonidae is a member of the canoid subgroup of carnivores. Their geologic history is old, going back to the late Eocene.
