Site summary
Read this summary in:

A colorful late-day wall dive built around crevice life rather than coral gardens — scarlet sponge and orange cup corals lit by dive lights, a big speckled moray, compatible with a giant moray, being cleaned, and a shift-change cast of lionfish, coral shrimp, and a thorny oyster.

Site description

Setting

A late-day wall dive that trades coral gardens for pure color: panels of scarlet sponge, yellow crusts, and orange cup corals compatible with Tubastraea that ignite under a dive light as the sun drops (e.g., Image 3).

Feydoo Wall is a crevice-hunter's dive.

Coral cover

Stressors

During a crown-of-thorns removal survey in May 2017, divers from Coral Reef CPR and Carpe Diem Maldives removed five crown-of-thorns starfish from this reef (Coral Reef CPR 2017).

Fish and other fauna

The dive's headline act is a big speckled moray — compatible with a giant moray — hanging head-down from its hole while bluestreak cleaner wrasses groom its jaws, orange basslets crowding the salon (e.g., Image 2, Image 5).

Look under the ledges for banded lionfish dangling upside-down, a coral shrimp waving long white antennae, a thorny oyster gaping its zigzag smile from a sponge-red wall, a spotted little puffer parked on a shelf, and a triggerfish already tucked into its bedroom crack for the night — the whole reef caught mid-shift-change between day and night crews (e.g., Image 4).

Comparisons with other data

Coral Reef CPR and Carpe Diem Maldives surveyed this site for crown-of-thorns sea stars in May 2017. Within 5 km, one independent station, WCS via MERMAID (MERMAID bleaching-protocol quadrats) at Villingilli, 4.36 km away, read 8.8% in 2016.

Coral cover score card

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 (MERMAID is a data platform: each MERMAID row names the organization that did the survey, and its method is in the row's hover text), so these are context for the figures above, not a like-for-like comparison. Where a station was surveyed more than once, the cell shows either the range of its values or, as a single value, the mean of surveys made in one year. Station names are not dive-site names.
