in biology, Canis Latrans Cagottis (Alias:Mexican Coyote , Smith's Coyote ,Synonyms: Lyciscus cagottis, Canis cagottis) It is one of the subspecies of coyote. The body weight is 8 to 22 kilograms, the body length is 70 to 97 centimeters, and the shoulder height is 45 to 53 centimeters. The body is medium and well-proportioned, with slender limbs and toes, which is conducive to fast running. The head and palate are pointed, the face is long, the nose is prominent, the ears are pointed and upright, the sense of smell is sensitive, and the hearing is well developed. The canines and cleft teeth are well developed; the upper molars have obvious cusps, and the lower molars have a small cusp and heel cusp on the inside; the diameter of the molar crown is greater than the height of the outer incisors; the tooth pattern is. The hair is thick and long, without patterns. The front feet have 4 to 5 toes, and the hind feet generally have 4 toes; the claws are thick and blunt, and cannot or are slightly retractable. The tail is droopy and hairy, more developed, half the body length, and there are odor glands at the root of the tail. Eye iris yellow. Males are on average larger than females. The coat color is usually greyish gray or a mixture of brown and gray. The coat on the back is dark and sometimes black, the throat and abdomen are light in color, the outer ears and legs are yellowish, and the lower body is gray or white.Coyote males average 8 to 20 kg (18 to 44 lb) in weight, while females average 7 to 18 kg (15 to 40 lb), though size varies geographically. Northern subspecies, which average 18 kg (40 lb), tend to grow larger than the southern subspecies of Mexico, which average 11.5 kg (25 lb). Total length ranges on average from 1.0 to 1.35 m (3 ft 3 in to 4 ft 5 in); comprising a tail length of 40 cm (16 in), with females being shorter in both body length and height. The largest coyote on record was a male killed near Afton, Wyoming, on November 19, 1937, which measured 1.5 m (4 ft 11 in) from nose to tail, and weighed 34 kg (75 lb). Scent glands are located at the upper side of the base of the tail and are a bluish-black color.
The color and texture of the coyote's fur vary somewhat geographically. The hair's predominant color is light gray and red or fulvous, interspersed around the body with black and white. Coyotes living at high elevations tend to have more black and gray shades than their desert-dwelling counterparts, which are more fulvous or whitish-gray. The coyote's fur consists of short, soft underfur and long, coarse guard hairs. The fur of northern subspecies is longer and denser than in southern forms, with the fur of some Mexican and Central American forms being almost hispid (bristly). Generally, adult coyotes (including coywolf hybrids) have a sable coat color, dark neonatal coat color, bushy tail with an active supracaudal gland, and a white facial mask. Albinism is extremely rare in coyotes. Out of a total of 750,000 coyotes killed by federal and cooperative hunters between March 1938, and June 1945, only two were albinos.
The coyote is typically smaller than the gray wolf, but has longer ears and a relatively larger braincase, as well as a thinner frame, face, and muzzle. The scent glands are smaller than the gray wolf's, but are the same color. Its fur color variation is much less varied than that of a wolf. The coyote also carries its tail downwards when running or walking, rather than horizontally as the wolf does.
Coyote tracks can be distinguished from those of dogs by their more elongated, less rounded shape. Unlike dogs, the upper canines of coyotes extend past the mental foramina.
