Many species of this fish can adapt extremely well to their environment. They can endure temperatures of 45–95°F (8–35°C), and can live in waters that are poorly oxygenated. The catfish can also secrete mucus that keeps it from drying out if it finds itself in an evaporating body of water. These abilities to adapt to its changing habitat show the creativity of this creature’s Creator.


  • The catfish is named for its prominent barbels, or “whiskers,” which look like cat’s whiskers.
  • The catfish has no scales, but has either thick leathery skin or armor.

Fun Facts
