Overview
Stokes's Sea Snake is among the heaviest-bodied of all sea snakes, with a girth that can exceed that of many terrestrial venomous snakes despite its moderate length. It inhabits coastal and reef waters across the tropical Indo-Pacific.
Its stout build and large fangs allow it to subdue armored or spiny prey such as catfish, and it possesses a comparatively large venom yield among sea snakes.
