This slender moray eel is found in the western Indian Ocean, from South Africa to the Red Sea. It grows to lengths of approximately 65 cm, and can be distinguished from other similar-sized morays by its pale yellow colouring, white eyes and
the delicate black spots that create unique patterns across the eel’s face. Geometric eels inhabit cracks and crevices in the reef wall up to depths of around 40 m, and are known to be synchronous hermaphrodites. This means that all eels produce both sperm and eggs, and can therefore mate successfully with any other member of their species. During the mating ritual, between 8,000 and 12,000 fertilised eggs are released at a time. Geometric eels are nocturnal hunters and prey predominantly on small fish.
