Saltwater crocodile
Distribution and habitat
The saltwater crocodile has the greatest size sexual dimorphism, by far, of any extant crocodilian, as males average about 4 to 5 times as massive as adult females and can sometimes measure twice her total length. The reason for the male skewered dimorphism in this species is not definitively known but might be correlated with sex-specific territoriality and the need for adult male saltwater crocodiles to monopolise large stretches of habitat. Due to the extreme sexual dimorphism of the species as contrasted with the more modest size dimorphism of other species, the average length of the species is only slightly more than some other extant crocodilians at 3.8–4 m (150–160 in). Play media The saltwater crocodile inhabits coastal brackish mangrove swamps and river deltas from India's east coast, Sri Lanka and Bangladesh to Myanmar, Thailand, Malaysia, Cambodia, Vietnam, Brunei Darussalam, Indonesia, Philippines, Palau, Solomon Islands, Vanuatu and Australia's north coast. The southernmost population in India lives in Odisha's Bhitarkanika Wildlife Sanctuary and in Subarnarekha and Budhabalanga Rivers. It occurs along the Andaman and Nicobar Islands coasts and in the Sundarbans. In Sri Lanka, it occurs foremost in western and southern parts of the country.
