Asian Common Toad

"One of the commonest of true toads in Southeast Asia, it occurs in a variety of habitats in both rural and urban areas. It ranges from Sri Lanka to Southern China, and down through Thailand, West Malaysia and Singapore to western Indonesia and the island of Borneo," but is an invasive in New Guinea. "There is considerable colour variation, but the species is easily identified by the presence of pronounced paratoid glands (a raised ridge behind the eye) and the lines of warts along the back and sides."
