Site summary

Read this summary in:

Komodo's dedicated night-dive and critter site, visited four times in six days, where the sand turned up flying gurnards, iridescent and tiny crinoid-dwelling cuttlefish, ornate ghost pipefish, bobtail squid, a possibly new octopus, and crabs living on fire urchins. Coral is a backdrop here rather than the draw, with beautiful soft corals on the slope.

Max. depth dived

20.4 m

deepest of 4 logged dives

Water temp. during survey

26.1°Cⁱⁱ

-2.1°C vs the 2019 mean sea temperature (28.2°C)

ii Dive-computer reading of 79°F, converted; reported to one decimal because the instrument resolved whole degrees Fahrenheit.

Site description

Fish and other fauna

Mating crabs, first flying gurnard, tiny cuttlefish, serpentine eels, nudibranchs, crocodilefish, cool, black, and white striped crab living on fire urchins, Halimeda crab, gorgeous, large, red nudibranch (e.g., Image 2).

Saw a new species of octopus scurrying across the sand. Got a decent picture. Iridescent cuttlefish (saw two and got good pictures). Ornate ghost pipefish, regular-sized cuttlefish, great critter hunting dive. Not as interesting as the previous two visits, but still saw some cool stuff: bobtail squid, shrimp, crab, flying gurnard, eels, nudibranchs, decorator crabs, cuttlefish (small), fire urchins with commensal crabs, and beautiful soft corals (e.g., Image 3, Image 4, Image 5).

Wasn’t the most interesting of the lot, but we still saw some cool stuff, including some never-before- seen lionfish, and small alligator or crocodilefish. Tiny cuttlefish living within crinoids (got decent pictures). Eel. Burrowing shrimp in perfectly cylindrical burrow (seen on another night dive).

Independent surveys nearby

Within 5 km, 1 independent survey station recorded hard coral cover in 2016. The most recent nearby survey is from 2016, so these values predate recent heat stress.

Collected by other programs using different methods, so these are context for the figures above, not a like-for-like comparison. Where a station was surveyed more than once the range is shown. Station names are not dive-site names.
