About Jahir

Jahir is a black sand muck site on the Sulawesi side of the Lembeh Strait, a gentle slope of sand, rubble and coral blocks known for frogfish: giant, warty and hairy frogfish, often four or five of them in one dive on a good day.

Jahir is one of the Lembeh Strait's best known frogfish sites. On the Sulawesi mainland side, a gentle slope of black volcanic sand runs down past patches of rubble and coral blocks, the kind of cover frogfish like to sit on.

Giant and warty frogfish are the regulars, and hairy frogfish turn up among the long-spined sea urchins. On a good day divers find four or five frogfish of different species on a single dive, and courting pairs have been watched here. The rest of the strait's muck life, from shrimps and crabs to nudibranchs, fills in between.

It is a shallow, easy dive with little current, suited to beginners with steady buoyancy.
