The Madagascar tilapia, Oreochromis Mossambicus



Oreochromus mossambicus, the Madagascar tilapia.

Tilapia or cichlids are small, present-day bony fish belonging to the order Perciformes and the family Cichlidae, one of the largest vertebrate families with over 3000 species.  Cichlids present a wide variation in social behavior, ranging from territorial to shoaling species, and in mating, including both monogamous and polygamous breeding (Simoes et al. 2012). They are found in East Africa, Madagascar, and western Asia, and also abundant in the West Indies, southern Mexico, and South America, with fossil evidence starting in the Miocene period.

The brain of  the Madagascar tilapia, Oreochromis mossambicus, was studied by Simoes et al. (2012) through a series of MRI scans which allowed them to make precise three-dimensional maps of brain areas, and compare these in detail with those of other cichlidae.
