The A. anhinga species is a large bird and measures 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. The A. a. anhinga subspecies is larger than A. a. leucogaster and has "broader buffy tail lips".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). The bill is relatively long(about twice the length of the head), sharply pointed and yellow as are the webbed feet.

Most of the male Anhinga's body is a glossy black green with the wings, base of wings, and tail being a glossy black blue. The tip of the tail has white feathers. The back of the head and the neck have elongated feathers that have been described as gray or light purple white. The upper back of the body and wings is spotted or streaked with white.

The female Anhinga is similar to the male Anhinga except that it has a pale gray-buff  or light brown head, neck, and upper chest. The lower chest or breast is a chestnut color and as compared to the male, the female has a more brown back.
