165438+1On October 4th-6th, the First Symposium on Snow Leopard Protection in Hengduan Mountain Area was held in Dujiangyan. At the seminar, Sichuan Wolong National Nature Reserve announced a new round of snow leopard data recovery results, and three infrared cameras in Weijiagou, Wolong found a family of four. It is understood that snow leopard is a solitary animal. He left his mother at about one and a half years old and lived alone, becoming an aloof, sensitive, alert and secretive "snow king in the mountains". It is extremely rare for four snow leopards to be in the same frame, which is also the first time that Sichuan has photographed it.

There are five videos shot by infrared cameras, three of which were shot in three days in June this year, on an alpine meadow dotted with sporadic flowers. The mother leopard slowly walked into the camera with three little snow leopards. The three little leopards stopped and stopped, looking forward to it curiously. When the mother leopard went out for food, three cubs sat quietly playing on the grass. According to the judgment of relevant experts, these three little leopards are about 3 months old, which is the lively and curious age.

Snow leopard is a big cat carnivore, named "Snow Leopard" because it often moves near the snow line and in the snow. Snow leopard has highly developed skills such as distributing blood and regulating breathing. Very sensitive to oxidation changes. The diameter of red blood cells is very small-5.5 microns (4.73 ~ 6. 15 microns), and hemoglobin is highly concentrated (16.4g%). The index of hematocrit (that is, the proportion of red blood cells is 47%) is consistent with a large number of red blood cells in the blood (14.1~168,000 /mm2). Snow leopards are native to the mountainous areas of Central Asia, and the high-altitude mountainous areas such as Tianshan Mountain in China are the main distribution areas of snow leopards. Its fur is gray, with black spots and black rings, and its tail is long and thick, so it is called "the snow king of the hill".

Snow leopard, body length 1 10~ 130 cm; The tail length is 90~ 100 cm and the weight is generally 50~80 kg.

The whole body is gray and covered with black spots. The black spots on the head are small and dense, and irregular black circles are formed on the back, body side and outer edges of limbs. As you get closer to your body, the black ring becomes bigger and bigger, and there are several small black spots in the black ring on your back and side of your body. There are no black spots in the black circle on the outer edge of limbs. The black spots on the back form three lines from the shoulder to the tail root. The black circle on the back is wide and large, and the tail tip is the most obvious.

The iris of the eye is yellow-green, and the pupil is round under strong light. There are many terminal keratinized barbs on the surface of the tongue, and the barbs at the tip of the tongue and the edge of the tongue form many fleshy protrusions. Five toes on the front foot and four toes on the back foot. The front foot is wider than the back foot, and the toes have horny hard claws, which are slightly curved and sharp. There are thick and long coarse hairs between toes, palm pads and toes. There are four pairs of nipples under the abdomen. The anus has a pair of breast holes.

The skull is slightly wide and round in shape. The ventricles are bigger. The broad process of frontal bone and the posterior part of zygomatic orbit are long and sharp. The nasal bone is short and wide, and the front end is particularly wide. The zygomatic arch is thick. The frontal process of maxilla is triangular, exceeding the posterior end of nasal bone. The orbital space is wider. Adult animals have high herringbone ridges, especially old bodies. The process of abnormal bone protrudes backward, sharp, thin and straight. The tympanum is flat and low, and the accessory occipital process is long, exceeding the auditory vesicle below. Mandibular bone is broad and its lower edge is straight.

Teeth: the upper and lower incisors are in a row, the middle pair of incisors is smaller and the lateral incisors are the largest. Canine teeth are developed and the inner blade is sharp. There are 3 maxillary premolars on the left and 3 maxillary premolars on the right. The second premolar is very small and has only one tip. The third premolar is flat and triangular, and there is an inconspicuous low tip behind the main tip. There are four tips on the outside of the upper cracked tooth. The second peak (front tip) is the largest, high and sharp, and there is only a low and small tooth tip (original tip) at the front end of the inner edge. Molars are as small as rows. There are only left and right lower premolars, the first and second premolars are missing, the third and fourth premolars are well developed, and the third premolars are mountain-shaped, with the main cusp in the middle and a small cusp in the front and back. The main point of the fourth lower premolar is high and located in the center, with one small tooth point in front and two small tooth points in the back. The lower molar is very large. The back tooth peak is slightly higher than the front tooth peak.

The cubs are all light rose purple. The outline of the black ring spot on the body is unclear and mixed with black ash.
