The Featherfin Catfish (Synodontis Euptera) is a species of catfish of the Mochokidae family, originally found in rivers and lakes of Central Africa, such as the White Nile river. These rivers have a rocky bottom, with an abundance of driftwood, large roots, and crevices, perfect for the Featherfin Catfish to hide from predators and scavenge for food.
The Synodontis Euptera is also known as the Featherfin Squeaker for its unique sound-producing abilities. The squeaking is accomplished by rubbing the spines of its pectoral fins into grooves on its shoulders – the sound is a defense mechanism against predators and competing Featherfins during mating season. It is also a way of communicating with one another in dark places, caves, and around the driftwood. They may also be called Lace Cat or Synodontis Lace Catfish.
