Hook-Nosed Sea Snake

Hook-Nosed Sea Snake's coloring acts as a countershading method of camouflage, in which its dark dark upper sides match the shade of the ocean depths it's at, and lighter undersides help it avoid looking dark against the bright sea surface.

The Hook-Nosed Sea Snake is grey on the upper half, with whitish or yellowish sides and lower half and grey-blue bars.

The long nose and shape gives the Hook-Nosed Sea Snake a beak or hook-like appearance.
