This species of lungfish inhabits a wide range of habitats in West and Middle Africa, and the northern half of Southern Africa. They have a long eel-like body, small eyes, a prominent snout, and two pairs of long, filamentous fins. During the dry season, they bury themselves deeply in the mud and go into a dormant state (estivation) in which they can survive without food and water for up to 3 ½ years.

Undersea Conversations…
While it isn’t obvious, fish have ears, and are able to communicate to one another through sounds. They don’t have vocal chords, but instead vibrate their swim bladders, producing popping, grunting, moaning, barking, or chirping noises. While some species of fish, like the goldfish, are silent listeners, there are over 1000 species that are known to vocalize, and some, like the gurnard who are veritable chatterboxes. While we can’t have a conversation with them - at least not yet - it is theorized that they do it to attract mates, frighten away predators or competitors, to synchronize mating, call for help and warn others, or to orient themselves.
