What is olive sea snake?

The olive sea snake (Aipysurus laevis) is a species of venomous sea snake found in the waters of Australia, New Guinea, and adjacent islands. It's a member of the family Elapidae, which also includes terrestrial snakes like cobras and taipans.

  • Description: Olive sea snakes have a robust body and a relatively small head. As their name suggests, they are typically olive-brown in color, but variations can range from dark brown to yellowish. They can grow up to 2 meters (6.6 feet) in length, although most individuals are smaller.

  • Habitat and Distribution: They inhabit coral reefs, rocky areas, and seagrass beds in tropical and subtropical waters. They are often found in relatively shallow areas, but can also be found at depths of up to 50 meters. Their range extends across northern Australia, including the Great Barrier Reef, to New Guinea and some nearby islands.

  • Diet: Olive sea snakes primarily feed on bottom-dwelling fish, crustaceans, and mollusks. They are known for their powerful bite, which they use to subdue their prey.

  • Venom: While venomous, olive sea snakes are generally not aggressive towards humans. Bites are rare, and fatalities are even rarer. Their venom is a potent neurotoxin and myotoxin, but the amount injected in a bite is usually small.

  • Reproduction: Olive sea snakes are viviparous, meaning they give birth to live young. Females typically give birth to between 2 and 25 offspring.

  • Conservation Status: The olive sea snake is listed as Least Concern by the IUCN. While they face some threats, such as habitat degradation and entanglement in fishing gear, their populations are currently considered stable.
