About the species

Stigmatochromis sp. "Big-head" is an undescribed predatory cichlid known from Domira Bay on the south-central Malawian shore, one of a number of populations informally distinguished from the genus's described species by field workers and collectors. The trade name is purely descriptive, referring to a conspicuously large, blocky head relative to the body, a trait that stands out against smaller-headed congeners at the same locality. Stigmatochromis is a genus of moderate to large ambush predators that lurk near rocky cover at the rock-sand interface and dart out at passing prey; like its relatives, this form is presumed piscivorous, though no dedicated study of this specific population has been published. It carries no scientific name, no describing author, and no Red List status.
