“海蛇”并非單一物種的專屬名稱，而是對一類適應海洋生活的蛇類的統稱，其英文表達為“sea snake”，這類爬行動物屬于海蛇科（Elapidae），主要分布于熱帶至亞熱帶海域，尤其以印度洋-太平洋區域最為集中，多數海蛇終生棲息于咸水環境，僅少數種類偶爾進入淡水，它們具有特殊的生理適應性：尾部扁平似槳助游動，部分種類可關閉鼻孔防止海水涌入，且肺部結構優化以支持潛水，海蛇多為卵胎生，幼體直接在水中孵化，值得注意的是，許多海蛇攜帶劇毒，其毒性遠超陸生蛇類，但對人類威脅較小，因性情溫順且主動避讓，作為海洋生態鏈的重要環節，海蛇通過控制魚類種群維持生態平衡，同時自身也是鯊魚、大型魚類及人類活動的獵物，研究海蛇的進化機制與生存策略，對揭示爬行動物向海洋過渡的演化歷程具有重要意義

Sea Snakes: An Overview

Sea snakes (scientific name: Hydrophiinae) are a group of highly venomous marine reptiles adapted to aquatic life. They belong to the elapid family and are primarily found in tropical waters of the Indian and Pacific Oceans12. Notable features include:

• Physical Adaptations: Sleek bodies, paddle-like tails for swimming, and specialized glands to extract oxygen from water14.
• Venom: Potent neurotoxins used to immobilize prey (e.g., fish, eels), though most species are non-aggressive toward humans unless provoked15.
• Reproduction: Unlike most reptiles, many sea snakes are viviparous (giving birth to live young)12.

Taxonomy and Diversity

The subfamily Hydrophiinae includes over 60 species, divided into two main groups:

1. True Sea Snakes (Hydrophiinae): Fully aquatic, with flattened tails and salt-excreting glands23. Examples:
   • Hydrophis platurus (Yellow-bellied Sea Snake)2.
   • Aipysurus duboisii (Dubois Sea Snake, one of the most venomous)4.
2. Sea Kraits (Laticauda spp.): Semi-aquatic, return to land to lay eggs45.

---

Ecological Roles and Threats

• Habitat: Coral reefs, seagrass beds, and coastal waters16.
• Conservation: Some species (e.g., short-nosed sea snake) are critically endangered due to habitat loss and bycatch6.

---

Notable Species

1. Yellow-bellied Sea Snake (Hydrophis platurus)
   • Distinct black back and yellow belly; widespread in tropical oceans2.
2. Leaf-scaled Sea Snake
   • Rediscovered in Shark Bay, Australia, after being presumed extinct6.

---

Human Interaction

• Myth vs. Reality: Despite their venom, fatalities are rare due to their shy nature15.
• Research Importance: Studies on their venom contribute to medical advances (e.g., painkillers)4.
