Pygmy raccoon

Description

The Cozumel raccoon (Procyon pygmaeus),also called the pygmy raccoon,is a critically endangered species of island raccoon endemic on Cozumel Island off the coast of the Yucatan Peninsula,Mexico.Merriam described the Cozumel raccoon as being markedly smaller,both externally and cranially and easy to distinguish from the common raccoon because of its "broad black throat band and golden yellow tail,short posteriorly expanded and rounded nasals and peculiarities of the teeth".Its reduced teeth point to a long period of isolation.Apart from its smaller size and more rounded snout,the Cozumel raccoon is similar in appearance to the common raccoon.The fur over the upper body is buff-grey ticked with occasional black hairs,while the underparts and legs are pale buff in color.The top of the head lacks the buff tinge of the rest of the body,and has a grizzled grey coloration,contrasting with the white fur of the muzzle and chin,and with the black "mask" pattern around the eyes.A line of brownish-grey fur runs down the middle of the snout,joining the "mask" patterns on either side.The tail is yellowish,with six or seven black or brown rings that become fainter on the underside.In males,the scruff of the neck has a patch of relatively bright,orange fur.Adults range from 58 to 82 centimetres (23 to 32 in) in total length,including the 23 to 26 centimetres (9.1 to 10.2 in) tail,and weigh between 3 to 4 kilograms (6.6 to 8.8 lb).This represents an example of insular dwarfism,and the animals are,on average,about 18% shorter and 45% lighter than the subspecies of common raccoon found on the local mainland,P.lotor shufeldti.Cozumel raccoons also exhibit sexual dimorphism,with the males being around 20% heavier than the females.
