The Chinese giant salamander is a species endemic to China. Its huge size and rare biology have fascinated scientists and conservationists. This profile provides a comprehensive overview of various aspects of this sadly endangered species. We go over its geographic range, physical characteristics, diet, behavior, conservation status, and the threats it faces. Understanding these elements is essential for informing conservation efforts and ensuring long-term survival. As we elaborate further below, its survival is important as it plays a significant ecological role in its native habitat.

Where Does the Chinese Giant Salamander Live?
Geographic range
Map by the IUCN (International Union for Conservation of Nature) & Conservation International 2020. Andrias davidianus. The IUCN Red List of Threatened Species. Version 2023-1. The orange is where the Chinese giant salamander is extant (resident), and the gray is where their presence is uncertain. To go to the original map, click the photo or click here.
The Chinese giant salamander (Andrias davidianus), is an amphibian native to the Yangtze River basin of central China. Historically, they were widespread in central, southwestern, and southern China, occupying tributaries of major rivers like the Pearl, Yellow, and Yangtze. However, their range has significantly contracted, relegating them to fragmented habitats within their native region.
This species prefers habitats with clear, rushing water and rocky crevices along the banks, where they can find refuge during the day. They typically inhabit streams of small width with quick flow and little depth, ranging in altitude from 100 to 1,500 meters. While they primarily reside in freshwater ecosystems, there have been instances of them being introduced to other regions, such as Kyoto Prefecture in Japan. However, such introductions pose threats to native species, as they can hybridize with them, potentially impacting local biodiversity. .
What Does the Chinese Giant Salamander Look Like?
Physical Appearance
The Chinese giant salamander is known for its big size and rare physical features. It has a large, flat head with small, lidless eyes and a wide mouth. Its dark, wrinkled skin is typically brown with a mottled or speckled pattern. Although, variations in coloration exist, including dark reddish and black hues. Notably, albinos have also been recorded with white or orange skin.
What makes them a giant? them measuring up to 1.8 meters in length and weighing as much as 50 kilograms. Its elongated body is supported by four stubby limbs, with a tail comprising over half its total length. As a “living fossil,” this species showcases the ancient lineage of amphibians and the importance of preserving their diminishing populations in the face of constant threats.

What Does the Chinese Giant Salamander Eat?
Diet
As apex predators of their habitats, Chinese giant salamanders play a crucial role in regulating ecosystem balance by preying on a diverse array of aquatic creatures. Their diet consists primarily of fish, frogs, worms, snails, insects, crayfish, crabs, and even smaller salamanders. They use an efficient suction-feeding technique to capture their prey, relying on sensory nodes along their body to detect vibrations in the water.
Despite their large size, Chinese giant salamanders are not immune to predation. Particularly in their juvenile stages, they may fall victim to larger predators, including other salamanders.
Are Chinese Giant Salamanders Dangerous?
Behavior
Although Chinese giant salamanders may look scary, they pose no direct threat to humans. With poor eyesight, they rely on specialized sensory nodes to detect prey through vibrations in the water. As nocturnal hunters, they are most active during the night, prowling their habitats in search of food. Despite their large size, they are generally docile creatures, preferring to avoid confrontation when possible.
Their susceptibility to human-induced threats, such as habitat destruction and overhunting, reminds us they are more likely to be hurt by humans than the other way around.
How Many Chinese Giant Salamanders Are Left?
Conservation status
The Chinese giant salamander was once relatively abundant throughout its native range, but now it’s on the brink of extinction. Classified as Critically Endangered by the International Union for Conservation of Nature (IUCN), its wild population has declined by more than 80% since the 1950s, primarily due to habitat loss, pollution, and overcollection. Despite legal protection and conservation efforts, including the establishment of nature reserves, the species continues to face severe threats.
Estimating the exact number of remaining Chinese giant salamanders in the wild is challenging due to their avoidant nature as well as their fragmented habitats. However, surveys conducted in recent years have yielded alarming results, with researchers unable to confirm the survival of wild populations at many surveyed sites.
Why are Chinese Giant Salamanders Endangered?
Threats
The Chinese giant salamander faces many threats that have pushed it towards extinction. Chief among these is overexploitation for human consumption and traditional medicine. Considered a delicacy in Chinese cuisine and believed to possess medicinal properties, they are heavily hunted despite legal protections. Additionally, habitat destruction and fragmentation, resulting from dam construction, urbanization, and agricultural expansion, have severely degraded their freshwater habitats.
Furthermore, pollution, including sedimentation, chemical runoff, and water contamination, significantly threaten their survival. These pollutants degrade water quality and harm salamanders directly, affecting their health and reproductive success. Climate change exacerbates these threats, leading to alterations in temperature and precipitation patterns that can further disrupt their habitats and food sources.
Conservation Efforts to Save the Chinese Giant Salamander
Despite the great challenges facing the Chinese giant salamander, conservation efforts are underway. These efforts encompass a range of strategies, including:
- Habitat protection: Several organizations, both governmental and non-governmental, are working tirelessly to establish protected areas, restore degraded habitats, and reduce human impacts on salamander populations.
- Captive breeding programs: Captive breeding initiatives play a crucial role in safeguarding the genetic diversity of Chinese giant salamanders and providing individuals for potential reintroduction into the wild. These programs require careful management to ensure the health and well-being of captive populations while minimizing the risk of disease transmission and genetic degradation.
- Community engagement and public education: Raising awareness among local communities and stakeholders about the importance of conserving this species is essential for garnering support for conservation efforts. In that same vein, collaborative research, information sharing, and capacity building can enhance conservation outcomes and promote sustainable management of freshwater ecosystems across borders.
Additionally, International cooperation is key to addressing the transboundary nature of the threats facing the Chinese giant salamander. By mobilizing resources, expertise, and political will at the global level, we can get closer to securing a future for this ancient amphibian.
Conclusion
It is important to protect our biodiversity, as they keep the balance in our ecosystems. Caring about saving endangered animals from going extinct, is caring about humans not going extinct because animals guard the earth and the resources humans need to survive. Without them we have nothing.
The Chinese giant salamander is a key species to the ecosystem of its native habitat. One that millions of humans rely on. Beyond their value measured in the benefits they provide to humans, they hold intrinsic value. It is imperative to get involved in actions geared towards halting its extinction.
In this blog, we do profiles of endangered species to bring them to the forefront of people’s minds. We want to put the spotlight on those not-so-famous animals that are close to going extinct so that people know them, understand their importance, and feel moved to help them.
