Walking catfish

Walking catfish is a species of airbreathing catfish native to Southeast Asia, but has been introduced to other parts of the world where it is considered an invasive species. The name "walking catfish" is derived from the fish's ability to walk on dry land to find food or suitable environments.

Description

The walking catfish is a long, slender fish that is scaleless and has a gray to brown body color. It can grow up to 24 inches in length. The fish has a pair of pectoral fins which are used for walking on land. The fish is able to breathe air using a structure in its gills called a labyrinth organ.

Habitat and Distribution

Walking catfish are native to Southeast Asia, including countries such as Thailand, Malaysia, and Indonesia. They prefer stagnant or slow-moving bodies of water with a soft, muddy bottom. The fish has been introduced to other parts of the world, including the United States, where it is considered an invasive species.

Behavior and Diet

Walking catfish are nocturnal and feed primarily on smaller fish and invertebrates. They are known to walk on land, especially during the rainy season when their habitat may become temporarily flooded. They are able to survive on land for extended periods of time due to their ability to breathe air.

Invasive Species

In areas where the walking catfish has been introduced, it has become a significant problem. The fish is able to quickly colonize new bodies of water, and its voracious appetite can lead to the decline of native fish species. In the United States, the fish is considered a prohibited species and it is illegal to possess, sell, or transport them.
