A yellow-lipped sea krait swims to the reef after surfacing for
a breadth of air in the Bohol Sea, Apo Island, the Philippines.

water, it dives straight back down vertically after filling its lungs.
The species is said to be more venomous than a cobra but
it’s not aggressive.| PORTFOLIONATURE68 76 April 2017April 2017
