Catfish Facts

Catfish is a type of fish that belongs to the group of ray-finned fish. There are more than 3000 species of catfish that can be found on all continents except on the Antarctica. Catfish inhabits freshwater ecosystems such as rivers and streams. Some species of catfish are adapted to the life in salt waters and caves. Catfish are one of the most farmed types of fish (their meat is consumed as delicacy around the world). Some types of catfish (such as Mekong catfish) are critically endangered due to overfishing and pollution of the water. Catfish are a group of bottom-feeding fish that are found in freshwater habitats and coastal regions on and around every continent in the world with the exception of Antarctica. Catfish are most easily identified by their flattened broad heads and the long whisker-like barbels that protrude from the mouth of the catfish.
