Sea snakes, or coral reef snakes, are elapid snakes that inhabit marine environments for most or all of their lives. They belong to two subfamilies, Hydrophiinae and Laticaudinae.

Sea snake, any of more than 60 species of highly venomous marine snakes of the cobra family (Elapidae). There are two groups: the true sea snakes (subfamily Hydrophiinae) and the sea kraits (subfamily Laticaudinae). Although their venom is the most potent of …

Sea Snakes are only moderately large, rarely exceeding 2 metres in length, often with peculiarly small heads for their body size. Only genus ‘Laticauda’ (which includes the Black Banded Sea Krait) has the typical broad ventral scales of snakes and it is often considered the least advanced of the sea snakes.

Sea snakes are one of the few reptiles to live in a fully marine habitat. They are specially adapted to survive in saltwater, and have a number of traits to help them live a seagoing life. Overall, this type of snake is a diverse and interesting group of animals.

Sea snakes are a fascinating group of reptiles uniquely adapted to marine life. These serpents prefer warm tropical and subtropical waters worldwide. Sea snakes comprise two distinct groups: true sea snakes, which spend most of their lives at …

2024年5月27日 · The sea snake is incredibly venomous, even more than a cobra! There are over 60 species of sea snakes that belong to the same family as cobras, Elapidae.

The yellow sea snake, Hydrophis spiralis, is recognised as perhaps the longest living sea snake in the world, recorded at nearly 3 metres long. Most sea snakes feed on fish. Their predators include sharks, large eels, sea eagles and large bony fish such as groupers.

Sea snakes are fully aquatic creatures that have adapted well to life in the sea. They have a flattened tail and the ability to close their nostrils, allowing them to partially breathe through their skin (up to 20% O2 and 100% CO2). They excrete salt through a gland under their tongue.

2025年2月13日 · The most venomous species is known as the hook-nosed sea snake or beaked sea snake (Enhydrina schistosa). It is estimated that only 0.02 mg of its venom per kilogram is enough to kill its prey, a smaller amount than that required by the most lethal terrestrial snakes. The latter usually need between 0.03 and 0.04 mg to cause the same effect.
