What is "ichthyophaga"

Ichthyophaga is a genus of two species of eagles, closely related to the sea-eagles in the genus Haliaeetus. Both are native to southeastern Asia, from the Indian subcontinent southeast to Sulawesi. They are smaller than the Haliaeetus eagles, though overlapping in size with the smaller species of that genus. They share similar plumage, with grey heads grading into dull grey-brown wings and bodies, and white belly and legs. They differ in tail colour, with lesser fish eagle having a brown tail, and grey-headed fish eagle having a white tail with a black terminal band, and also in size, with lesser fish eagle only about half of the weight of grey-headed fish eagle.
