2. The following physiological data contains almost all the physiological characteristics of the beast: (1) Compared with the skull, the lion is slightly longer than the tiger, and the tiger is slightly wider than the lion, but the advantage of the largest individual lion is slightly obvious. The largest individual lion's skull is 432 mm long and 275 mm wide. The second largest lion's skull comes from a black maned lion standing in Southeast Asia, with a shoulder height of 109cm and a skull length of 420. Therefore, the length of the skull cannot be used as a basis for judging the size of an individual, because under the condition of equal surface area, the more square and sleek the body shape of an object is, the bigger it is, the longer it is, the smaller it is, the longer the lion's skull is, and the more round the tiger's skull is, so the tiger's brain capacity is larger, and the bite force is also related to the skull length. According to the lever principle, the energy consumed is the same. Because the lion's skull is longer than the tiger's and the radial vector of torque is larger than the tiger's, it
The mane is a symbol of the lion and a tool evolved from the big cat fight. Because the male testosterone secretion of the male lion is the highest among cats, the male lion is extremely fierce in the fight, but lacks skills. Biologically speaking, the function of male lion mane is defined as: the display of strength between male lions, the standard of self-protection, and the standard of mate selection for female lions. The mane has little defensive effect, because whether a lion or a lioness fights, locking their throats is not their offensive means, and they prefer to bite each other's back half. (2) The heart capacity of the lion is slightly larger, but there is almost no difference in hemoglobin content between the two, except that the tiger is bigger, so compared with the lion, the tiger is more prone to fatigue.
(3) Compared with the lion's forelimb, liger's forelimb is the longest, but its arm circumference is slightly smaller than that of liger's, and they are similar. Generally speaking, Tiger Claw's arch is larger, while the lion's slenderness ratio (ud) is slightly larger. Look at that four-corner claw. It's straighter. (4) The strength of hind limbs is similar to that of hind limbs. (5) Muscle Tigers and lions are both tropical and subtropical, and their muscles are similar. The lion's shoulders are very strong, because the lion has to hold its huge prey with its two front paws, while the tiger's strength is relatively uniform, which can be said to be that its limbs are thick. The longer the arms of deltoid and pectoralis major (that is, the insertion depth of the spinous process of humerus to which they are attached), the more helpful it is for big cats to subdue large prey. On the humerus, the greater the ratio of the length of spinous process/triangular crest (the part where pectoralis major is attached) to the length of humerus, the greater the leverage. The following are the results of two different studies; The average result is: lion: 0.64301349 82911052423 tiger: 0.6236538+0469593. In other words, the lion's shoulder structure is more conducive to exerting strength, not scratching bones. Under the same muscle strength, the lion's shoulder strength is greater than that of the tiger, but the tiger's bone density and muscle density are greater than that of the lion. (6) The eye length of sighted lions and tigers is generally larger than that of tigers. Tigers have more cones than lions, and lions can only concentrate limited cones on their prey, and their vision is blurred. (7) The conclusion of the speed paper is that the lion is slightly faster than the tiger at present, but not much faster. But the tiger's beak structure and spine setting are better, so the acceleration may be no less than that of a lion.
(8) The fur of a fur tiger is thick but too soft, and the fur toughness of a lion is much better than that of a tiger. African aborigines often use sun-dried lion skins as shields. (9) Acrobatic Circus liger can also perform acrobatics. As for personality, lions and tigers have no objective standards. What is cunning, what is straightforward, what is simple and honest, and what is insidious? This is a subjective feeling of human beings and cannot be evaluated at all. Observers have at most some subconscious tendencies psychologically. (1 1) Activity (10) Compared with sleep time in liger, there are more lions. Lions sleep 18 hours and tigers sleep 16 hours on average every day. The moving distance of the desert lion is 9 1 day, 940.9km, with an average of10.34 km; Every day; The average traveling distance of male Siberian tiger is 9.6km, and the highest is 41km. . The average distance of women walking day and night is 7 kilometers, and the highest is 22 kilometers. Through comparison, it is found that the moving distance of the desert lion exceeds that of the Northeast Tiger! (1 1) The success rate of lion hunting is about 20%, and that of tiger hunting is about 5- 10%. In Ranthambhore National Park, the main foods are white deer and water deer, with livestock accounting for about 10% and no bison. The average is about 107- 1 14 kg. The average weight of tigers in Pench Park is 65.5kg, and only the most frequently hunted species are considered, with an average weight of 9 1.5kg. In Nepali Chitwan Park, among Hu Meng's prey, 27.8% are sika deer, 15.3% are water deer, 13.5% are crested deer, 6.4% are muntjac, 10.8% are wild boar, 2.7% are porcupine and 6.6% are porcupine. Deer accounted for 50.3% of Hu Meng's diet, water deer accounted for 6.3%, Luze accounted for 5.7%, bison accounted for 4.8%, langur accounted for 2 1.6%, porcupine accounted for 10.3%, and wild boar only accounted for 1%. The average weight of all prey in Huikaken Nature Reserve, Thailand (here, zhina) is 66kg. Macaques and langurs account for 10.8%, porcupines for 27.65,438+0%, and pigs and badgers for 17.9%. The average weight of all prey is 14.7kg. In nagar Huo National Park, 22.8% of Hu Meng's diet is spotted deer, and water deer accounts for 65,438+065,438+. Long-tailed langur accounts for 1 1.3%, spotted elk accounts for 13.6%, rabbit accounts for 1.5%, porcupine accounts for 0.6%, jackal accounts for 1%,1 The prey of Amur tiger: Xihaote-Alin Nature Reserve 1933- 1994. The feeding habits of tigers in different periods: from top to bottom, the Chinese names of various prey are: wild ungulates: red deer, wild boar, sika deer, musk deer, moose, impala and roe deer; Others: tiger, bear, wolf, lynx, badger, raccoon, mink, grouse. For nearly a century, the staple food of tigers has been wild boar and red deer; Tigers feed on large and medium-sized ungulates, which account for a large part of the tiger's diet, almost all; Tigers rarely eat each other. Average prey weight of Siberian tiger: 77kg- 15 1kg African lion prey: People usually think that lions mainly attack old, weak, sick and disabled animals: in fact, lions mainly prey on mature prey-except adult male bison or big male giraffes. In terms of average weight, the male lion is the largest (399kg), followed by the female lion (126kg). As can be seen from the table, social lions are suitable for killing large prey, not only because lions choose a larger weight for the same prey; Because small prey may not be enough to eat, but a single lion is generally afraid to attack bison and larger animals. (12) Homogeneous competition: the probability of tiger being killed by the same kind is 5.5%; Lions are 13%, and the frequency of similar fights is much higher.
Usually, the probability of tigers meeting each other is very small, and there is little chance of fighting. Lions live in open grasslands, and their territory is smaller than that of tigers. There are often fights between intruders and landlords. But tigers, like lions, will do what they can, but they will stop fighting and run away. When Noci and his son invaded Fang's territory, Fang fled without fighting, leaving his wife and children, who were underage, but they also had to leave their homes and began to wander. (13) Evolutionary liger came from the same ancestor. At present, it is impossible to meet wild liger. Before human interference, tigers used to be all over the forests of the Asian continent, showing tenacious adaptability from extreme cold to extreme heat, while lions were also widely distributed in the vast grasslands of Europe, Asia and Africa. Lions in zoos in Northeast China also grow long body hair to keep out the cold in winter, which proves that their ancestors once settled in northern Eurasia.
