About the species

Stigmatochromis macrorhynchos is a predatory haplochromine cichlid documented from the rocky waters around Mumbo Island, inside Lake Malawi National Park. Its epithet, "large-snouted," points to an elongated jaw suited to seizing prey, a hallmark of the ambush-hunting Stigmatochromis, a genus whose best-known member is famous for a startling hunting trick — lying motionless on its side to mimic a dead fish and lure scavengers within striking range.
