How do sea snakes resemble their relatives on land?

Sea snakes resemble their land relatives, such as cobras and other elapids, through their elongated bodies and similar head shapes, which facilitate their predatory lifestyle. Both groups possess highly venomous fangs, adapted for subduing prey. Additionally, like some terrestrial snakes, sea snakes have a flattened tail that aids in swimming, showcasing a shared evolutionary adaptation to their respective environments. Despite their aquatic lifestyle, their physiological traits reflect their common ancestry with land-dwelling snakes.
