Elapidae ~ Venomous Snakes
97 terrestrial species, 31 sea snake species and 2 species of sea kraits.
Venomous front fanged snakes that dominate Australian snake fauna. The family consists of land snakes, sea snakes and sea kraits. They range from highly venomous land snakes of over 2.5M to weakly venomous burrowers of less than 30cm.
Sea snakes feed and breed entirely in the sea and never voluntarily venture onto land. Sea kraits taxonomically speaking fall between sea snakes and terrestrial elapids. They have a vertically flattened and paddle shaped tail like sea snakes and laterally positioned nostrils and broad laterally expanded ventral scales like terrestrial elapids.
