Sleep goby

Introduction: The sleep goby (Dormitator lebretonis) is a species of gobioid fish found in certain regions of Namibia. It belongs to the Eleotridae family and is known for its unique behaviour of entering a state of dormancy during dry periods when water levels are low.

Distribution: The sleep goby is native to specific areas of Namibia, particularly in regions with suitable freshwater habitats. It can be found in slow-moving or stagnant waters, often near the edges of rivers, streams, and flooded areas.

Diet: As an omnivorous species, the sleep goby has a varied diet that includes aquatic insects, small crustaceans, algae, and detritus. During the dry season, when water levels decrease, it may bury itself in mud and detritus to survive until more favorable conditions return.

behaviour: One of the most intriguing aspects of the sleep goby is its ability to enter a dormant state during periods of low water levels. When its aquatic habitat dries up, the fish buries itself in mud or detritus, secretes a mucus cocoon around its body, and enters a state of dormancy (aestivation) until the rainy season returns.

colouration: The sleep goby has a relatively plain colouration, with a brownish or olive-coloured body that helps it blend into its muddy surroundings.

Size: This species of gobioid fish is small to medium-sized, with adult individuals typically reaching lengths of about 8 to 12 centimetres.
