The anhinga (/ æ n ˈ h ɪ ŋ ɡ ə /; Anhinga anhinga), sometimes called snakebird, darter, American darter, or water turkey, is a water bird of the warmer parts of the Americas. The word anhinga comes from a'ñinga in the Brazilian Tupi language and means "devil bird" or "snake bird". [ 3 ]
The term snakebird is usually used without any additions to signify whichever of the completely allopatric species occurs in any one region. It refers to their long thin neck, which has a snake-like appearance when they swim with their bodies submerged, or when mated pairs twist it during their bonding displays.
The body remains submerged as it swims, and the slender neck alone is visible above the water, which accounts for the colloquial name of snakebird. Like the cormorants, it has wettable feathers and it is often found perched on a rock or branch with its wings held open to dry.
The African darter is found throughout sub-Saharan Africa wherever large bodies of water occur; overall the species remains widespread and common. [1]The only non-African subspecies, the Levant darter (Anhinga rufa chantrei), occurred at Lake Amik (Amik Gölü) in south-central Turkey, in the Hula Valley lake and marshes in northern Israel and in the Mesopotamian Marshes of the lower Euphrates ...
John Gould described the Australasian darter as Plotus novaehollandiae in 1847. [2] Closely related to American (Anhinga anhinga), African (Anhinga rufa), and Oriental (Anhinga melanogaster) darters, the Australasian darter has been classed as a subspecies of the African or African plus Oriental darters.
The eastern indigo snake was first described by John Edwards Holbrook in 1842. For many years the genus Drymarchon was considered monotypic with one species, Drymarchon corais, with 12 subspecies, until the early 1990s when Drymarchon corais couperi was elevated to full species status according to the Society for the Study of Amphibians and Reptiles, in their official names list.

Twig snakes are among the few rear-fanged colubrids whose bite is highly venomous and potentially fatal. [4] The venom is hemotoxic, and although its effects are very slow, and bites are rare, no antivenom has been developed and several fatalities (such as Robert Mertens) have occurred.
