环纹海蛇游向水面，安达曼海，泰国

d sea krait (Laticauda colubrina) lifts off an Andaman Sea reef and swims upward into open water, leaving the coral structure below as it heads toward the surface, illustrating natural sea snake behaviour and reef predator movement. Sea kraits must periodically surface for air despite hunting underwater, and unlike fully aquatic sea snakes that never leave the water, this species also returns to land to digest food and lay eggs. 4K, wide angle, vertical wide shot, scuba diver POV. Andaman Sea, Krabi Province, Thailand.
