Maldives - Ari Atoll south tip

Setting

Two dives at Ari's southern tip, and both extremes of reef drama in one morning.

General benthic features

Yet the reef shoulder still carries dense living coral thickets, anemone gardens with a crimson, balled-up showpiece hiding its anemonefish, a cruising sea turtle, and clouds of anthias along the drop (e.g., Image 3, Image 4, Image 6, Image 7, Image 16, Image 17, Image 18, Image 19, Image 21).

Coral cover

Coral cover: 19% — photo-derived, and the two methods broadly agree (19% vs 19%). This site's figure is the mean of two independent computer vision passes over Anderson's own frames: a DINOv3 calibrated point classifier reads 18.5% and a CoralSCOP computer vision reads 18.7%, a spread of 0.2 percentage points. The map publishes the mean so sites can be sorted against one another, but the honest statement of what is known here is the 19–19% range: the two products have different denominators and should not be treated as one measurement.

Stressors

Under the overhangs lurks the villain: crown-of-thorns seastars in their gothic blue-violet livery, wedged two to a crevice, and all around them the fresh white skeletons of staghorn and cauliflower corals eaten in the preceding days — the photographer bluntly labels it an outbreak (e.g., Image 1, Image 2, Image 5, Image 8, Image 9, Image 10, Image 11, Image 12, Image 13, Image 14).

Fish and other fauna

Then, on the second dive, the blue delivers a whale shark — first a ghostly bulk in the haze, then the full constellation of pale spots gliding along the slope while divers scramble (e.g., Image 15, Image 20, Image 23, Image 24, Image 25).
