Description

The largechin hap is a cichlid endemic to Lake Malawi in East Africa. The species grows to about 20 cm and has a streamlined body with large eyes and a conspicuously developed lower-jaw sensory system with large pores, adapted to detect vibrations and prey in the dim depths. It is more or less evenly distributed below 60 metres and prefers sandy bottoms. As a bottom searcher it sifts small invertebrates from the sediment with its lower jaw against the bottom. As a maternal mouthbrooder the female carries the eggs and young in her mouth. The species is harmless to humans.
