Balasa

Balasa is a genus of large sea snakes belonging to the subfamily Hydrophiinae. These snakes are found in the warm tropical waters of the Indian and Pacific Oceans. They are characterized by their flattened, paddle-like tails, which are used for propulsion through the water, and their ability to hold their breath for extended periods. Balasa sea snakes are highly venomous, possessing potent neurotoxic venom that they use to subdue their prey, which typically consists of fish. Despite their venomous nature, they are generally not aggressive towards humans and bites are rare, usually occurring when the snakes are accidentally caught in fishing nets.

There are several recognized species within the Balasa genus, each with slightly different geographical distributions and physical characteristics. These snakes are ovoviviparous, meaning they give birth to live young. They play a role in the marine ecosystem as predators, helping to regulate fish populations. Due to their aquatic lifestyle, Balasa sea snakes have specialized adaptations, including valved nostrils that can be closed to prevent water from entering, and their scales are not designed for terrestrial movement. Conservation efforts are important for these species as they can be vulnerable to habitat degradation and bycatch in fisheries.
