Nile Perch (Lates niloticus), FMNH no. 55359. Field Museum of Natural History, Chicago. Conservation status: least concern. Important commercially, this species is under threat from overexploitation and pollution throughout its range in the northern half of Africa. However, as a voracious predator and through competition for food, it is responsible for the decimation and possible disappearance of over 200 other fish species when it was introduced into Lake Victoria. Conservation action is needed but not enough is known of its population numbers and range, biology and ecology so the species is assessed as 'data deficient' until more information is available. As biologists describe new species and add to our understanding of the interrelated nature of life on Earth, a species becomes extinct every 20 minutes (100 to 1000 times the background extinction rate as seen in the fossil record). Collections in natural history museums play important roles in conservation, education and research. Most of that work and the associated specimens are not on public display in museums typically, less than five percent of specimens are exhibited.
