Description
This species is characterized by a wide variation in number of ventral scales and degree of parietal scale fragmentation. Both sexes possess spiny scales along their bodies but males have more highly developed spines. This sexual dimorphism in spines may play a role in courtship or in locomotion by reducing drag.
Range & habitat
It is a widely distributed species and like most sea snakes is restricted to warmer, tropical waters. Its range includes:
Persian Gulf (Oman, Bahrain, United Arab Emirates, Iran) Indian Ocean (Bangladesh, Pakistan, Sri Lanka, India) South China Sea (north to the coasts of Fujian and Shandong) Strait of Taiwan Indo-Australian Archipelago North Coast of Australia (Northern Territory, Queensland, Western Australia) Philippines (Panay) Pacific Ocean (Myanmar, Thailand, Indonesia, China, Japan, New Guinea) Andaman & Nicobar Islands, Cambodia and Singapore
