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...
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...
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...
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...
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...
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, ...
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...
The release of heavy metals from commercial deep-sea mining is likely to be a long-term process lasting decade, and therefore fish communities are actually exposed to a chronic, ongoing stressor. Howe...
There is a common misconception among ocean scientists and policy makers that mesopelagic (200-1000 m) food webs are an unexploited "final frontier" of living marine resources. It is true that there a...
Marine hatchetfish (Stomiiformes: Sternoptychidae) are among the most abundant and diverse inhabitants of the mesopelagic zone. Despite their small size, they have a high global biomass and play a cru...
Microplastic contamination in aquatic ecosystems has emerged as a major environmental concern due to its potential impact on marine organisms and human health. The present study investigates the abund...
The effectiveness of passive acoustic monitoring (PAM) for studying marine biodiversity highly relies on comprehensive libraries of species-specific sounds. While sound production is well-documented i...
