The anomalous sea snake is a venomous snake that lives only in seawater. It inhabits coastal areas of Southeast Asia and almost never comes ashore.
The anomalous sea snake differs from related species by its special scale structure on the head. It is important for marine nature as a predator that controls the population of small fish and serves as food for large marine animals.
Legendary longevity: over 100 years. Galapagos tortoises, Greenland sharks, ocean quahogs celebrate with family once every 4 years
Immature form that undergoes metamorphosis before adulthood.
