Dwarf stonebasher

Introduction: The dwarf stonebasher (Pollimyrus castelnau) is a species of freshwater fish belonging to the family Mormyridae. It is known for its unique appearance and remarkable electroreceptive abilities.

Habitat: The dwarf stonebasher is native to various river systems in Africa, particularly those within the Okavango Basin, upper Zambezi River, Kafue and Kunene Rivers. It inhabits slow-moving waters, including rivers, streams, and flooded areas with submerged vegetation. These habitats provide the fish with suitable conditions for its electrocommunication behaviour.

Electric Organ: The dwarf stonebasher is famous for its elongated snout, which houses specialized electrocytes. These electrocytes enable the fish to generate weak electric fields for communication, navigation, and detecting objects in its environment.

Diet: As a nocturnal predator, the dwarf stonebasher primarily feeds on small aquatic organisms such as insects, insect larvae, crustaceans, and other tiny invertebrates. Its electroreceptive abilities aid in locating prey even in low-light conditions.

Electrocommunication: The dwarf stonebasher uses its electric field for communication, both for social interactions and detecting objects. It can generate distinctive electric signals that carry information about its species, gender, and even mood. These signals play a crucial role in courtship and territorial behaviour.

Conservation Status: Like other fish species in African river systems, it may face habitat degradation and alterations due to human activities.

Physical Description: The dwarf stonebasher has a unique appearance with an elongated snout resembling an elephant's trunk. Its body is laterally compressed, and the colouration can vary from dark to light depending on the individual and its environment.

behaviour: This fish is known for its nocturnal and shy behaviour. It often spends daylight hours hiding among aquatic vegetation or other cover. During the night, it becomes more active, searching for food and engaging in electrocommunication activities.

Size: In its natural habitat, the dwarf stonebasher can reach a length of approximately 10 to 15 centimetres. The elongated snout is a prominent feature, and it contributes to the fish's unique appearance.
