The catfish is a fish that lives in freshwater and saltwater. Their color can vary from blue to black or olive. The average length of a catfish is 36 to 53 inches long. The average weight is 30 pounds. Most catfish have smooth skin without scales. They are covered with mucus. The catfish has many family members, including Channel Catfish, Blue Catfish, and Flathead Catfish.
Catfish are omnivores. They eat plants and meat. When they are young, they eat insects such as dragonflies, water beetles, and fly larvae. When they are adults, they eat small fish, seeds, aquatic plants, algae, crawfish, and snails. Most catfish have small eyes and find food by using their barbells, their sense of smell, and their sense of taste.
Channel catfish can live in both freshwater and salt water. They are found in lakes, reservoirs, and ponds. Catfish live in warm waters. Catfish live in deep holes, overhangs and other locations that provide shelter or at the bottom of a body of water. Catfish live on their own.
Catfish have adaptations to help them survive. The spines on the dorsal and pectoral fins protect the catfish. The darker color helps camouflage it at the bottom of the water. Enemies of the catfish are larger fish, birds, reptiles, mammals and humans. The catfish uses its spines to protect itself. Some catfish produce poison in the glands in the skin.
June 25th is National Catfish Day. There are more than 3,000 species of catfish. The smallest catfish is less than half of an inch long. The largest catfish (Mekong Catfish) can reach 9 feet long and weighs 646 pounds.
Catfish are interesting creatures. They are an important part of the water ecosystems and our world.
