Lembeh Strait (Indonesia: Selat Lembeh) is a narrow stretch of water between Sulawesi and Lembeh Island (Pulau Lembeh), Indonesia. Lembeh Strait is world-known for its extremely high density of rare and unusual marine life, in particular stingray and flying gurnard.
Stingrays are a group of sea rays, which are cartilaginous fish related to sharks and common in coastal tropical and subtropical marine waters throughout the world.
Stingrays are not usually aggressive and ordinarily attack humans only when provoked, they are progressively becoming threatened or vulnerable to extinction, particularly as the consequence of unregulated fishing.
Flying gurnard (Dactylopterus volitans) also known as the helmet gurnard, is a bottom-dwelling fish of tropical to warm temperate waters. Flying gurnard can reach up to 50 cm in length, its main diet consists of small fish, bivalves, and crustaceans.
Flying gurnard is variable in coloration, being brownish or greenish with reddish or yellowish patches.When excited, the fish spreads its "wings", which are semi-transparent, with a phosphorescent bright blue coloration at their tips.
The camouflage of this flatfish is excellent, you can barely see it on the ocean floor.
There are also many beautiful sea urchins on the seabed, but no one lays eyes on them since the other creatures here are more attractive.
