The automatic monitoring of fish in underwater imagery plays a key role in marine ecology, fisheries management, and environmental monitoring, yet progress is limited by the lack of large, high-qualit...
Deep-diving surveys enable observations of new features of behavioural and functional dimensions of the fish that are typically missing from specimen-based taxonomy. This study documents three rare ar...
Evolutionary habitat transitions are known to drive rapid evolution. In fishes, switches between marine and freshwater can promote adaptation in sensory systems; in particular, the disparate visual en...
The dragonfishes and allies (Stomiiformes) are among the most species rich and ecologically important clades of deep-sea fishes. Within the Stomiiformes, the marine hatchetfishes (Sternoptychidae) are...
The deep sea hosts approximately 15% of all fish species, but the difficulty of sampling limits our knowledge, causing large gaps in geographic distribution, and many deep-sea fish groups still requir...
Knowledge on the ecology and life-history traits of coastal marine species is vital to inform their conservation and management, especially as their coastal habitats come under increasing threats. How...
Environmental DNA (eDNA) is increasingly used for assessing marine biodiversity, yet its potential for monitoring seasonal dynamics in tropical coral reef ecosystems requires further systematic invest...
Anglerfishes (Lophiiformes) have evolved diverse morphological solutions for life in the deep sea (>200 m). Previous studies have shown that the bathypelagic lineage (Ceratioidei) exhibits high evolut...
Ocean warming and acidification pose significant threats to marine biodiversity and human nutrition by fundamentally altering the biochemical composition of marine organisms. A primary concern is the ...
Oxygen levels in the ocean have decreased worldwide as a result of climate change and nutrient contamination, which has had a significant impact on marine ecosystems. Although deep-sea fish that resid...
The mesopelagic zone, between 100 and 1000 m depth, contains up to 90% of marine vertebrate biomass. Mesopelagic fishes are key components of these ecosystems through their feeding interactions and pl...
We investigated the metabolic rate of Western Atlantic hagfish (Myxine limosa Girard, 1859) in response to cold temperatures, time of day and conspecific defensive slime exposure. Closed-chamber respi...
Animals have evolved diverse mating strategies to cope with limitations on mate encounter and secure reproductive success. One of the most extreme examples is found in deep-sea anglerfishes, in which ...
Robust biodiversity monitoring is essential for the management of UNESCO World Natural Heritage Sites; yet, systematic assessments of ichthyofaunal communities remain limited. Here, we apply environme...
Mesopelagic fishes transport a vast biomass of organic material between surface and deep waters through diel vertical migration (DVM), which plays a crucial role in both food web functioning and deep-...
The University of Washington's marine field station, the Friday Harbor Laboratories (FHL), has been a center for diverse biological research for over 100 years. The facility is a complete mini-campus ...
The functioning of high-diversity ecosystems, such as coral reefs, is intrinsically tied to the integrity and efficiency of the trophic pathways within these systems. Coral reef productivity depends, ...
A new genus and species of Clavella-like specimens parasitic on Macrourus holotrachys, previously reported as a host for Clavella adunca, clearly differ from the latter in the position and condition o...
Members of the bacterial family Endozoicomonadaceae are ubiquitous marine symbionts associated with diverse hosts, including corals, sponges, molluscs, and fishes. Despite their ecological pervasivene...
The hagfish eye is highly reduced, lacking pigment and a lens, and covered by soft tissue. The timing and mode of this loss of complexity remain unknown. Here, we present high-resolution anatomical da...
