The luminescence comes from symbiotic bacteria, which are thought to be acquired from seawater, [2] [3] that dwell in and around the sea. Some anglerfish are notable for extreme sexual dimorphism and sexual symbiosis of the small male with the much larger female, seen in the suborder Ceratioidei, the deep sea anglerfish.
A very rare fish sighting is making a splash on social media. A deep-sea anglerfish, with its mouthful of sharp teeth, was spotted near the surface of the water near the Canary Islands off the ...
For the deep-sea ecosystem, the death of a whale is the most important event. A dead whale can bring hundreds of tons of organic matter to the bottom. Whale fall community progresses through three stages: [32] Mobile scavenger stage: Big and mobile deep-sea animals arrive at the site almost immediately after whales fall on the bottom.

Many eels, both reef, benthic, and deep-sea, nocturnally migrate to the surface layer as larvae. [64] But while the ocean's surface may seem like an odd habitat for larval deep-sea fish, they are far from the most unusual. Diverse fish that migrate into freshwater as adults (either as a habitat or spawning ground) rely on the neuston when young.
A team led by scientists at Lancaster University in the UK found that the fish are becoming more scared of humans and spending less time on courting behavior, with potentially important impacts on ...
There is a two-way interplay between human attitudes, beliefs, and symbols concerning fish, such as in Christianity, and people's practical use of and dependency on fish: "Fish not only guarantee the necessities of human life as food for the world, but they also establish human and fish relationships that link social, cultural, traditional, and ...
