About the species

Trematocranus brevirostris is a small haplochromine cichlid documented from the South East Arm of Lake Malawi. It belongs to a genus best known for one of the lake's most specialised feeding tricks — extracting the soft body of a snail whole from its shell without breaking it — and its own epithet, "short-snouted," marks it out from its genus-mates by proportion of jaw rather than by colour.
