The White-bellied Sea-Eagle has white on the head, rump and underparts and dark grey on the back and wings. In flight the black flight feathers on the wings are easily seen when the bird is viewed from below. The large, hooked bill is grey with a darker tip, and the eye is dark brown. The legs and feet are cream-white, with long black talons (claws). The sexes are similar. As in other raptors (birds of prey), Males (2.5 kg - 3.7 kg) are slightly smaller than females (2.8 kg - 4.2 kg).The wingspan is about 1.8 m - 2 m. Young Sea-Eagles are brown as juveniles than slowly become to resemble adults in a patchwork manner, acquiring the complete adult plumage by their fourth year.
The White-bellied Sea-Eagle is the second largest raptor (bird of prey) found in Australia. The largest is the Wedge-tailed Eagle, Aquila audax, which stands up to 1 m tall. The Wedge-tailed Eagle is mostly brown, with a wedge-shaped tail. Young Sea-Eagles may be confused with the Wedge-tailed Eagle, but differ in having a paler head and tail and more steeply upswept wings when soaring.
The White-bellied Sea-Eagle feeds mainly off aquatic animals, such as fish, turtles and sea snakes, but it takes birds and mammals as well. It is a skilled hunter, and will attack prey up to the size of a swan. Sea-Eagles also feed on carrion (dead prey) such as sheep and fish along the waterline. They harass smaller birds, forcing them to drop any food that they are carrying. Sea-Eagles feed alone, in pairs or in family groups.
