The anhinga is a large bird, measuring approximately 89 cm (35 in) in length (with a range of 75–95 cm (30–37 in)), with a 1.14 m (3.7 ft) wingspan.[10][11] The A. a. anhinga subspecies is larger than A. a. leucogaster and has broader buffy tail tips.[5] They weigh on average around 1.22 kg (2.7 lb), with a range of 1.04–1.35 kg (2.3–3.0 lb).[11][12][13] The bill is relatively long (about twice the length of the head), sharply pointed, and yellow, and the webbed feet are yellow as well.[7][14][10][12]

The male is a glossy black-green with the wings, base of wings, and tail a glossy black-blue.[14] The tip of the tail is white.[15] The back of the head and the neck have elongated feathers that have been described as gray[16] or light purple-white.[14] The upper back of the body and wings are spotted or streaked with white.[16]

The female anhinga is similar to the male except for its pale gray-buff[17] or light brown[18] head, neck, and upper chest. The lower chest or breast is a chestnut color, and the back is browner than the male's.[19]

The hatchling starts bald but gains tan down within a few days of hatching. Within two weeks, the tan down is replaced by white down. Three weeks after hatching, the first juvenile feathers appear. Juveniles are mostly brown until they first breed, usually after the second or third winter.[4]

This bird is often mistaken for the double-crested cormorant due to its similar size and shape, although the two species can be differentiated by their tails and bills. The tail of the anhinga is wider and much longer than the cormorant's. The bill of the anhinga is pointed, while the bill of the cormorant has a hook-tip.[20]

Like other species in the genus, anhingas have a noticeable "kink" midway up their necks. This is due to the peculiar morphology of the eighth cervical vertebra
