Mesophotic coral ecosystems (MCEs; ∼30 to 150 meters) are major but poorly understood benthic habitats. We used Autonomous Reef Monitoring Structures (ARMS) and integrated metabarcoding (mtCOI and 18S...

A transparent goby fish drifted through the darkness, its skeleton visible through paper-thin skin. Nearby, a sea slug wore yellow polka dots like a party dress, while an orange fish with bulging…

A livestream of an undersea project has captivated Argentina as President Javier Milei wields a chain saw on the budget for science.

Genetic bottlenecks are evolutionary events that reduce the effective size and diversity of natural populations, often limiting a population's ability to adapt to environmental change. Given the accel...

Deep-sea hydrothermal vent ecosystems are sustained by chemoautotrophic bacteria that symbiotically provide organic matter to their animal hosts through the oxidation of chemical reductants in vent fl...

Corals and other marine invertebrates host diverse microbes that remain poorly characterized, especially in the deep sea. Here the authors discover a new clade of bacteria with uniquely streamlined ge...

The deep-sea benthos often exhibit exceptional biodiversity. The patch-mosaic hypothesis proposes that this deep-sea diversity arises from varied microhabitats with prolonged temporal persistence fil...
