Spot-Billed Duck
The Spot-billed Duck (Anas poecilorhyncha) also known as the Spotbill, is a dabbling duck which breeds in tropical and eastern Asia. It has three subspecies: the Indian Spot-billed Duck (A. poecilorhyncha poecilorhyncha), Eastern Spot-billed Duck (A. poecilorhyncha zonorhyncha), and Burmese Spot-billed Duck (A. poecilorhyncha haringtoni).This duck is around the same size as a Mallard. It measures 55–63 cm (22–25 in) in length and 83–95 cm (33–37 in) across the wings, with a body mass of 790–1,500 g (1.7–3.3 lb).[3][4] These are mainly grey ducks with a paler head and neck and a black bill tipped bright yellow. The wings are whitish with black flight feathers below, and from above show a white-bordered green speculum and white tertials. The male has a red spot on the base of the bill, which is absent or inconspicuous in the smaller but otherwise similar female. Juveniles are browner and duller than adults.

These snakes are generally found in the coast and coastal islands of India. They are amongst the most common of the 20 kinds of sea snakes found in that region. They are active both during the day and at night. They are able to dive up to 100 m and stay underwater for a maximum of five hours before resurfacing. Sea snakes are equipped with glands to eliminate excess salt. They are venomous and notably aggressive, with some herpetologists describing them as "cantankerous and savage". The venom of this species is made up of highly potent neurotoxins and myotoxins. This widespread species is responsible for the vast majority of deaths from sea snake bites .
