Description
Size: The maximum length of this sea snake is 113 cm.

Habitat: These snakes are restricted to tropical and subtropical waters. They are usually found within a few kilometers of the coast and prefer shallow inshore waters. Normally these snakes live in waters with temperatures between 11.7 and 36 degrees Celsius.

Reproduction: This snake reproduces sexually in water, usually near the surface. It breeds in water with a temperature greater than 20 degrees Celsius. This species is ovoviviparous, and gestation is thought to be 5 to 6 months. One to 10 young are born per litter, each 220-260 mm long at birth. Adult males grow to greater than 600 mm.

Lifespan / Longevity: In captivity 2.1 years.

Behavior: These snakes feed during the day and spend nights on the ocean bottom, occassionally rising to the surface to breath. They can dive to maximum depths of 6.8 m in the dry season, and 15.1 m during the wet season. Sea snakes can stay underwater between 1.5 and 3.5 hours. They are capable of cutaneous breathing, removing oxygen from the water and releasing carbon dioxide. The yellow-bellied sea snake has a salt gland under its tongue, which secretes salt taken in from the water. It swims on the surface by sideward undulations aided by the laterally compressed tail, which acts as a paddle.
