Chinese giant salamander
The Chinese giant salamander is a large amphibian native to the freshwater rivers and streams of China, distinguished by its sizable body, oversized heads, and a coloration that ranges from brown to gray. As the largest living amphibian, they can grow between three to six feet long and weigh up to 110 pounds. These nocturnal creatures are ambush predators, primarily feeding on fish, crayfish, and other smaller animals, relying more on their senses of smell and touch due to their poor eyesight. The species demonstrates monogamous breeding behavior, with a breeding season from August to September where females lay hundreds of eggs in protective caves.
Unfortunately, the Chinese giant salamander faces significant threats, including hunting, over-fishing, and habitat destruction, leading to a critically endangered status according to the International Union for Conservation of Nature (IUCN). Their lifespan can reach up to 60 years in both wild and captive settings, highlighting their role as apex predators within their ecosystem. Understanding the ecological importance and current conservation challenges facing the Chinese giant salamander is crucial for efforts to protect this remarkable species.

Chinese giant salamander
Chinese giant salamanders look very much like Japanese giant salamanders. They are large, brown or gray amphibians with huge heads and bodies.
Kingdom: Animalia
Phylum: Chordata
Class: Amphibia
Order: Urodela
Family: Cryptobranchidae
Genus: Andrias
Species: Davidranus
Chinese giant salamanders and Japanese giant salamanders differ only in their location. Chinese giant salamanders live in the freshwater flowing rivers and streams of China, instead of Japan. Like other giant salamanders, Chinese giant salamanders are nocturnal, or night-active. They spend their days resting underneath or between rocks and logs and spend their nights hunting prey.
Chinese giant salamanders are ambush predators that feed on a variety of fish, crayfish, snails, insects, worms, and smaller salamanders. This type of diet makes Chinese giant salamanders carnivores, or meat-eating animals.
Chinese giant salamanders are the largest living member of the class Amphibia. They are brown or gray with oversized, pancake-shaped heads and bodies. Their skin color and fleshy bodies help them to blend in with their muddy surroundings. Chinese giant salamanders are between three and six feet (91 to 183 centimeters) long. Their average weight is 24 pounds (11 kilograms) but they can weigh up to 110 pounds (50 kilograms). They have very poor eyesight because their eyes are positioned far apart on their large, broad heads. Because of this, Chinese giant salamanders use their senses of smell and touch to help them find food. In addition to having poor eyesight, Chinese giant salamanders lack eyelids.
Like other amphibians, Chinese giant salamanders begin their lives in eggs, then go through a larval stage, and then grow into their adult forms. Chinese giant salamanders breed every year. Their breeding season is from August to September. They are monogamous creatures, meaning they have a specific partner that they mate with. After breeding, females lay their eggs in caves, and males then protect the eggs from predators. They typically lay between 300 and 600 eggs. The larvae are independent when born and typically live in the bodies of water they are born in.
Chinese giant salamanders are apex predators, meaning they are at the top of the food chain, so they do not have specific predators except humans. They are hunted and consumed by humans, and over-fishing and habitat loss have caused a decline in population. The Chinese giant salamander is listed as critically endangered by the International Union for Conservation of Nature (IUCN).
Chinese giant salamanders may have life spans of up to 60 years in both the wild and captivity.
