A night dive at Pulau Misool (18 October 2018, 65 minutes, to 17.7 m): strobe-lit close-ups of a banded coral shrimp, a green-polyped laminar coral, feather stars and a sea squirt, and two walking (epaulette-type) sharks resting on rubble. No coral-cover figure is published for this site.

Site description

Setting

Anderson's night dive at Pulau Misool on 18 October 2018 entered the water at 18:40 and lasted 65 minutes, to a maximum depth of 17.7 m; the dive computer recorded a single water temperature of 27.5°C. The five frames described here are close, strobe-lit night shots rather than wide reef views.

General benthic features

A laminar coral colony with evenly spaced green polyps, compatible with Turbinaria, overhangs a dark recess beside a lilac encrusting sponge (e.g., Image 2).

A wider frame crosses a pale slope of coral rubble and broken framework, with a mottled, well-camouflaged animal at left that the frame does not resolve (e.g., Image 3).

Another shows a rocky outcrop crowded with orange and black feather stars, a yellow sea squirt, small green bubble algae, finger-like branching coral, and soft corals (e.g., Image 4).

Coral cover

Stressors

Anderson took no notes on this night dive (18 October 2018); the log lists only fauna (mating walking sharks, shrimp, walking brittle stars, nudibranchs, and ghost pipefish), so no bleaching, disease, crown-of-thorns starfish, or other stressor is recorded.

Fish and other fauna

A banded coral shrimp (Stenopus hispidus) stands among red encrusting growth with its long white antennae spread (e.g., Image 1).

Two walking sharks of the epaulette type (Hemiscyllium) rest together on the rubble (e.g., Image 5).
