life habit

Snakehead is a strong aquatic animal. It usually likes to inhabit the lush or muddy water bottom. When small fish and shrimps swim near, it will launch a raid to swallow these small animals. A 0.5 kg snakehead can swallow a grass carp or carp in one bite. Snakehead has a strong vitality and ranks first among freshwater fish.

Ophiocephalus argus is a benthic fish, which usually lives in still water or micro-flowing water with overgrown aquatic plants and soft sediment, and is distributed in lakes, rivers, reservoirs, ponds and other waters. Often dive to the bottom of the water to swing its pectoral fins to maintain body balance.

Snakehead has strong adaptability to the changes of environmental factors in water, especially to hypoxia, water temperature and poor water quality. When the water is short of oxygen, it can keep its head out of the water.

Snakehead has a strong jumping ability. When the weather is sultry and rainy and the water rises, mullet often jumps out of the water and escapes along the pond bank. When there is a running water impact, it will also arouse the fish to jump and escape. If the bait in the pond where he lives is insufficient, he will also move to other ponds, and his body will move forward slowly like a snake when moving.
