With God I shall fight for home and for hearth,

I trade thee not, for anything in a world

Lates niloticus is silver in colour with a blue tinge. It has distinctive dark-black eyes, with a bright-yellow outer ring. One of the largest freshwater fish, it reaches a maximum length of nearly 2 m (more than 6 ft), weighing up to 200 kg (440 lb). Mature fish average 121137 cm (47.554 in), although many fish are caught before they can grow this large.
Adult Nile perch occupy all habitats of a lake with sufficient oxygen concentrations, while juveniles are restricted to shallow or nearshore environments. A fierce predator that dominates its surroundings, the Nile perch feeds on fish (including its own species), crustaceans, and insects; the juveniles also feed on zooplankton. Nile perch use schooling as a mechanism to protect themselves from other predators.
Nile perch have been introduced to many other lakes in Africa, including Lake Victoria (see below) and the artificial Lake Nasser. The IUCN's (World Conservation Union) Invasive Species Specialist Group considers L. niloticus one of the world's 100 worst invasive species.
The state of Queensland in Australia levies heavy fines on anyone found in possession of a living Nile perch, since it competes directly with the native barramundi, which is similar and grows to 1.8m long while the Nile Perch grows to 2m long.
The species is of great commercial importance as a food fish. The Nile perch is also popular with sport anglers, as it attacks artificial fishing lures and is also raised in aquaculture.
The first European to study the species was the English explorer and naturalist John Whitehead in 1896, who observed the bird and whose servant, Juan, collected the first specimen a few weeks later. The skin of the bird was sent to William Robert Ogilvie-Grant in London in 1896, who initially showed it off in a local restaurant and described the species a few weeks later.
Upon its scientific discovery, the Philippine eagle was first called the monkey-eating eagle because of reports from natives of Bonga, Samar, where the species was first discovered, that it preyed exclusively on monkeys; from these reports it gained its generic name, from the Greek pithecus () ("ape or monkey") and phagus (-) ("eater of"). The species name commemorates Jeffery Whitehead, the father of John Whitehead. Later studies revealed, however, that the alleged monkey-eating eagle also ate other animals, such as colugos, civets, large snakes, monitor lizards, and even large birds, such as hornbills. This, coupled with the fact that the same name applied to the African crowned eagle and the Central and South American harpy eagle, resulted in a presidential proclamation to change its name to Philippine eagle in 1978, and in 1995 was declared a national emblem. This species has no recognized subspecies.
Apart from Philippine eagle and monkey-eating eagle, it has also been called the great Philippine eagle. It has numerous names in the many Philippine languages, including gila ("eagle"), hribon (from haring ibn, "king bird") and banog ("kite").
