Abu Galawa-small centers on a heavily coral-colonized shipwreck - far more densely settled than either Saudi wreck in this set - whose Acropora and encrusting corals were found almost entirely bleached brilliant white against the rust-brown steel hull, with the adjacent natural Porites-and-Acropora slope also extensively pale. Published cover was 22% with 61.3% of coral tissue bleached; notably, the wreck itself is not mentioned anywhere in the site's existing description despite being its defining feature.
يتمحور موقع أبو جلاوة الصغير حول حطام سفينة استوطنه المرجان بكثافة — أكثف بكثير من أي من الحطامين السعوديين في هذه المجموعة — وقد وُجدت مرجانيات Acropora والمرجانيات المتقشرة عليه مُبيَّضة بالكامل تقريباً ببياض ساطع في مواجهة الهيكل الفولاذي البني الصدئ، كما كان المنحدر الطبيعي المجاور من Porites وAcropora شاحباً على نطاق واسع.

4 of these 50 photographs are shown beside the text that discusses them under "Site description" below.
The wreck is the site's defining feature and it is not mentioned anywhere in the site record. The frames show a substantial steel vessel lying over on the reef, its hull ribs and deck framing standing open like a cage, plating rusted to deep red-brown and orange, with the reef itself visible through the gaps.
It is far more heavily colonized than either of the Saudi wrecks in this set — coral has settled across the frames, the ribs, and the plating, in real density rather than as a scatter. Off the wreck, the natural reef is a slope of massive Porites and mixed Acropora over pavement, also extensively pale, running down onto sand (e.g., Image 1, Image 2, Image 3, Image 4).
Coral cover is 21.5% ± 17.5 across 192 photographs, quoted verbatim from Mayfield, A.B. (2025) Environments 12:248 — Red Sea 2023-24 bleaching; CoralNet point annotation, Appendix A — a manual, diver-annotated CoralNet point count from Anderson's own published work, not a computer vision output and not recomputed here.
The site record reports 61.3% of coral tissue bleached at about 21.8°C-weeks DHW. And nearly all of the coral on it is white. Half a dozen table and corymbose Acropora colonies growing directly on the wreck structure are bleached brilliant, uniform white, standing out against the rust-brown steel; the smaller encrusting and knobby colonies between them are pale blue-white.
