Cameras or Divers? How Baited Remote Underwater Videos and ‘Long Swims’ Underwater Visual Census Complement Each Other on Coral Reefs

open access: yesEcology and Evolution, Volume 16, Issue 4, April 2026.
This study compares baited remote underwater videos (BRUV) and a rapid timed long swim (LS) UVC method to evaluate their ability in assessing relative abundance and diversity of large predatory reef fish from nine selected families. BRUVs were more effective in detecting mobile and bait‐attracted taxa such as Carangidae and recorded up to 28 unique ...

Structure of Mesophotic Reef Fish Assemblages in the Northwestern Hawaiian Islands.

open access: yesPLoS ONE, 2016
Mesophotic coral ecosystems (MCEs) support diverse communities of marine organisms with changes in community structure occurring along a depth gradient. In recent years, MCEs have gained attention due to their depths that provide protection from natural ...

Marine Heatwaves Have Increased in Frequency, Duration, and Depth Across Southeast Asia

open access: yesJournal of Geophysical Research: Oceans, Volume 131, Issue 4, April 2026.
Abstract Southeast Asia supports high marine biodiversity that is increasingly exposed to intensifying marine heatwaves (MHWs). Despite the ecological and socio‐economic consequences of thermal anomalies, the regional spatio‐temporal dynamics and vertical structure of MHWs remain poorly constrained. Here, we use satellite‐derived surface and reanalysis

Cover Image

open access: yesEcosphere, Volume 17, Issue 6, June 2026.
COVER PHOTO: Red gorgonians (Paramuricea clavata) and black corals (Antipathella subpinnata) form dense animal forests on mesophotic reefs (40–100 m) of the Aegean Sea. The diversity and distinctiveness of fish communities found in these mesophotic animal forests were investigated through visual census and collection of cryptic species by rebreather ...

An underwater imagery identification guide for shallow, mesophotic and deep-sea benthos in Maldives [PDF]

open access: yesBiodiversity Data Journal
During the 2022 Nekton Maldives Mission, we deployed a variety of platforms (snorkelling, remotely-operated vehicles and manned submersibles) to conduct video surveys of the biodiversity and composition of shallow (< 30 m), mesophotic (30-150 m ...

A new species of Litarachna (Acari, Hydrachnidia, Pontarachnidae) from a Caribbean mesophotic coral ecosystem

open access: yesZooKeys, 2014
Hydrachnidia) from the Caribbean island of Puerto Rico are presented. Litarachna lopezae sp. n., from substrata collected from Bajo de Sico, a mesophotic coral reef ecosystem in Mona Passage off Puerto Rico, is described as new to science. The new species was collected from nearly 70 m depth, the greatest depth from which pontarachnid mites have been ...

SubCAS: A Portable, Submersible Hyperbaric Chamber to Collect Living Mesophotic Fishes

open access: yesFrontiers in Marine Science, 2018
Accompanying the recent technological innovations in remotely operated vehicles (ROVs), submersibles, technical SCUBA, and closed-circuit rebreather diving gear, new discoveries are being made on mesophotic coral ecosystems around the world.

A Rare Benthic Ctenophore, Lyrocteis cf. imperatoris, at Mesophotic Depths off Réunion Island

open access: yesDiversity
Closed-circuit rebreather diving has opened new opportunities for direct observation of the rich biodiversity of unexplored mesophotic coral ecosystems. We recently encountered four specimens of a rare benthic ctenophore genus, Lyrocteis.
