Kloss's Sea Snake

Kloss's sea snake is a relatively small marine elapid found in the coastal waters of the Gulf of Thailand and adjacent parts of the South China Sea. It is named in honor of the naturalist Cecil Boden Kloss, who contributed to the documentation of Southeast Asian fauna.

As a member of the Hydrophis clade, it shares the fully marine lifestyle and paddle-tail adaptation typical of true sea snakes, and remains a relatively poorly studied species compared to more widespread relatives.

• Small to moderate-sized, slender body
• Pale grey to olive coloration with darker crossbands along the body
• Bands may be more pronounced on the back and fade toward the belly
• Smooth, overlapping body scales
• Narrow head not strongly distinct from the neck
• Laterally compressed tail adapted for swimming
• Adults typically reach 0.6-0.9 m in length

Inhabits shallow coastal waters over soft substrates within the Gulf of Thailand and nearby South China Sea coastal zones. Associated with estuarine influence and areas with abundant small fish prey.

Forages for small fish along the seabed, likely using both visual and chemosensory cues typical of the genus. Activity patterns are not extensively documented but likely include both diurnal and nocturnal foraging. Reproduction is ovoviviparous, with live young born at sea.
