About the species

Telmatochromis temporalis is a stocky, bulldog-faced lamprologine cichlid endemic to Lake Tanganyika, instantly set apart from its slim, Julidochromis-like relatives by a deep body and a blunt nuchal hump. What makes it a textbook fish, though, is that it comes in two very different packages: a normal rock-dwelling form that grows to a few inches and shelters under stones, and a much smaller dwarf form that lives buried in the empty snail shells of the lake's shell beds. Biologists treat the pair as a living snapshot of speciation in progress, with body size itself acting as the lever that is prying the two forms apart.
