Lava Flow
The 1988 eruption of Gunung Api sent lava into the sea on the volcano's northern side and wiped out the reef there. Within a few decades a remarkably dense hard coral garden grew back on the cooled basalt: fields of staghorn and table coral in the shallows, cabbage coral deeper down, from about 3 m to 40 m. Reef fish are abundant, with clown and black triggerfish, Napoleon wrasse, batfish and cuttlefish; upwellings sometimes bring plankton, mobula rays, dogtooth tuna and bluefin trevally.
depth: 3–40 m
