Wild populations are only distributed in the Anhui Province, and the natural population size has remained at approximately 150 individuals for 20 years. The Chinese alligator is a member of the alligator family that lives in China. The Chinese alligator and the American alligator, are the only extant species in that genus.

These secretive alligators spend a large par… Currently this species is classified as Critically Endangered (CR) on the IUCN Red List. [17] This behavior gives it the ability to live in areas where humans are common. [2] In 1982, the Anhui National Nature Reserve for Chinese Alligator (ANNRCA) was created, a reserve spanning across the entire range of the Chinese alligator,[23] now covering an area of 18,565 hectares (45,880 acres). Largely nocturnal because of human persecution, they stay in their tunnels much of the day when humans are in the vicinity, as well as during cool weather and winter months. Nest mates may spend weeks to years together in the protection of the mother. What are synonyms for Chinese alligators? An alligator is an apex predator in its environment, known to even hunt animals that are much larger in size. [31] The main purpose of these bellows is to call out to alligator specimens to collect at a specific pond, where individuals choose mates and engage in copulation. Its area of distribution is shrinking quickly due to the development of agriculture and human expansion. Each year in April, the alligators emerge from their winter burrows and find sunny spots in which to bask. The fossil is estimated to be from the late Pliocene period, 3 million years ago (Mya). In historical times, the Chinese alligator was found in the extensive lakes and marshlands of the middle-lower Yangtze River region and along the river from Shanghai to Jianling City in the Hubei Province. Large specimens achieve 2.1 m (7 ft) and 45 kg (100 lb), although there have been mentions about specimens that are supposed to be 3.0 m (10 ft) long. Alligators and caiman differ from other crocodiles mainly due to the teeth on the lower jaw being inserted into small cavities in the upper jaw, so that they are not visible when their mouths are closed. [61] According to The New York Times, the association with the "beneficent" mythological creature is an advantage for the species. They can reproduce into their 50s. The Chinese alligator is in desperate need of habitat conservation and protection in the wild. Dentition includes blunt teeth adapted well to crushing shelled animals. These include American and Chinese alligators. Its head is robust, more so than that of the American alligator,[16] with a bony septum dividing its nostrils. [26], The alligator grows quickly in its first few years, with its growth rate slowing at age five. Regression equations between body–size and head–size variables were presented to predict body size from head dimension. The most common chinese alligator material is metal. A study of 50 clutches showed multiple paternity in 60% of them, with up to three males contributing. The largest Chinese alligator measured in recent times was 7 feet and 1 inch--about half the size of the largest living American alligators. [12] According to The New York Times, the population was less than 130 in 2001; at this time, alligators sometimes wandered around to look for a suitable habitat, but were unsuccessful due to their habitat having been turned into rice fields.

Both sexes may react very aggressively to one another, especially in first encounter situations. [6] Marco Polo was the first person outside of China to write about the alligator, when he came to China and saw it in the late 1200s. A higher incubation temperature also increases the hatching rate. However, in the 1950s, it was found exclusively in the southern portion of the Yangtze River. [4] A year after the 2007 release, 16 young alligators were found living in the wild. In both species, males tend to be larger than females. The most popular color? Egg size also varies with species; female gharial produce the largest eggs of any crocodilian (∼160 g), while the Chinese alligator produces much smaller eggs (∼50 g). As apex predators alligators have a formidable array of weaponry – both offensive and defensive. [36], The Yangtze was flooded in the winter of 1957, which is believed to have caused many Chinese alligators to drown. [2] A majority of the species' wetland habitats were destroyed to construct rice paddies[34] and dams. [45] Captive-born Chinese alligators have been reintroduced into their native range, boosting the wild population. [9] Fauvel wrote a detailed description of the species in a book titled Alligators in China: Their History, Description & Identification,[10] including information about its historical account. Because islands frequently satisfy both of these conditions, they are often used as nesting sites.

[30], Both sexes participate in bellowing choruses during the mating season as adults. [6] Chinese alligators were later thought to give Buddhist priests merit if the priests were to buy alligators held in captivity and release them.
