In total, ~ 80 hrs of stereo-video footage were collected during the benthic transect surveys, which were subsequently processed using annotation software in order to evaluate benthic biodiversity and community composition. Here, we present a photographic guide for the visual, <jats:italic>in situ<\/jats:italic> identification of reef benthos encountered, including corals, sponges and other invertebrates that inhabit Maldives\u2019 nearshore habitats. We hope that this identification guide will aid future imagery-based surveys or observations of organisms during fieldwork.<\/jats:p>\n          <jats:p>A total of 283 morphotypes were identified, including those belonging to Octocorallia (61), Scleractinia (57), Porifera (38), Asteroidea (22), Antipatharia (15), Decapoda (13), Hydrozoa (12), Holothuroidea (10), Actiniaria (9), Echinoidea (8), Annelida (6), Chlorophyta (5), Gastropoda (4), Bivalvia (4), Ascidiacea (3), Crinoidea (3), Bryozoa (2), Cyanobacteria (2), Zoantharia (2), Cephalopoda (1), Ceriantharia (1), Corallimorpharia (1), Ctenophora (1), Ophiuroidea (1), Rhodophyta (1) and to an unknown category (1). Out of these, we identified 40 to species level, 120 to genus, 47 to family, 14 to order and suborder, 58 to class and subclass, two to phylum and one was of unknown phylum. This represents the first attempt to catalogue the mesophotic and deep-sea benthic megafaunal diversity in the Maldives using underwater imagery.<\/jats:p>","DOI":"10.3897\/bdj.12.e120128","type":"journal-article","created":{"date-parts":[[2024,6,18]],"date-time":"2024-06-18T18:22:03Z","timestamp":1718734923000},"source":"Crossref","is-referenced-by-count":1,"title":["An
