Karang Hatta
Karang Hatta (also Skaru/Sekaru, 'shallow area') is a submerged reef a couple of kilometres south of Pulau Hatta: a hard-coral plateau some 500 m wide slopes to about 40 m before dropping into the abyss. Southerly currents on the south-east side gather fish so thick it is hard to see past them — fusiliers, red-tooth triggerfish, snappers and surgeonfish — while dogtooth tuna, great barracuda, eagle rays, whitetip sharks, green turtles and occasionally mobulas or scalloped and great hammerheads patrol the blue.
depth: None–40 m
