Herpetology Notes, volume 8: 323-328 (2015) (published online on 26 May 2015) Micropechis ikaheka (Elapidae) in Papua, Indonesia: A Study of Diet and Cannibalism Keliopas Krey1,2,*, Mark O’Shea3, Achmad Farajallah1, Dede Setiadi1 and Bambang Suryobroto1 Introduction vegetation, discarded rubbish from cocoa, coconut or palm oil industries, holes in fallen palm trees, under Snakes are primary predators in many terrestrial, tree buttresses, and in rocky crevices (Hudson, 1988; aquatic, and marine communities. As predators, the lives O’Shea, 1994b; O’Shea, 1996; Krey and Farajallah, of wild snakes are therefore closely related to feeding 2013). ecology. Feeding ecology is related not only to food Micropechis ikaheka exhibits a very generalized diet availability but also to the body sizes of the predators (Shine and Keogh, 1996), comprising lizards, snakes, and prey (Cundall and Greene, 2000). Studying the frogs, and small mammals. Some specific dietary items diet of a snake species is critical to our knowledge of have been reported, including the New Guinea ground the ecology of the snake at individual, population and boa Candoia aspera (O’Shea, 1994a), and skinks community levels. Ecological studies of snake diets are Sphenomorphus jobiensis (McDowell, 1984; Shine and also very important for a better understanding of the Keogh, 1996) and S. simus (Krey, 2009). relationships between snakes and other organisms in the O’Shea (1994b) reported cannibalism in the species, ecosystem (Su et al., 2005). in captivity. He described a small female predated by The New Guinea small-eyed snake, Micropechis a larger female. This case of cannibalism, in a group ikaheka (Lesson 1830), is one of the most venomous of freshly-caught snakes destined for venom research, terrestrial snakes of continental New Guinea, occuring demonstrates a feeding behaviour that may also occur from lowland wetlands and plantations to mid-montane in wild populations.
