Yellow-lipped sea krait

The yellow-lipped sea krait (Laticauda colubrina) is a venomous amphibious sea snake of tropical Indo-Pacific waters, recognized by its yellow snout and dark-banded body.

Laticauda colubrina: A sea krait species with a yellow snout and banded body, distributed across the tropical Indo-Pacific. This is the scientific species name for the yellow-lipped sea krait.
Counterillumination: Camouflage that reduces an animal's visible silhouette by matching the light from its underside to the surrounding background. The pale underside may reduce contrast when the snake is viewed underwater.
Coral reef: A marine ecosystem built largely by reef-forming corals and supporting diverse communities of organisms. The snake hunts and shelters around coral reefs.
Banded sea krait: A sea krait species, Laticauda semifasciata, with dark bands and a range in the western Pacific. It is a close relative with overlapping habitat and similar amphibious habits.
Sea snake: A venomous snake adapted to marine life, including fully aquatic hydrophiines and amphibious sea kraits. The yellow-lipped sea krait belongs to the broader group of marine snakes.
Lateral undulation: A form of locomotion in which waves of side-to-side bending travel along an animal's body. Body undulation propels the sea krait through water and across land.
Moray eel: A family of predatory reef fishes with elongated bodies and jaws adapted for catching prey in crevices. Moray eels are among the fishes this sea krait hunts.
Blue-lipped sea krait: A sea krait species, Laticauda laticaudata, distinguished by blue coloration around the mouth and dark bands. This related species shares the genus but differs in coloration and distribution.
Elapidae: A family of venomous snakes that includes cobras, kraits, mambas, and coral snakes. Its venomous ancestry places the species within this snake family.
Paddle-shaped tail: A flattened tail that increases surface area for propulsion through water. Its laterally compressed tail provides thrust during swimming.
