"The findings break from the traditional interpretation of marine ecology found in textbooks, which states that nearly all sunlight in the ocean is captured by chlorophyll in algae. Instead, rhodopsin-equipped bacteria function like hybrid cars, powered by organic matter when available — as most bacteria are — and by sunlight when nutrients ...
It can be found free-swimming in tropical marine waters, commensally in the gut microflora of marine animals, and as both a primary and opportunistic pathogen of a number of marine animals. [151] It is thought to be the cause of the milky seas effect , where a uniform blue glow is emitted from seawater during the night.
There are only 11 known "supergiant" and nine "giant" Bathynomus species, and this is only the second supergiant to be found in the South China Sea. A view of the Bathynomus vaderi from the top ...
The most abundant concentrations of salps are in the Southern Ocean [4] (near Antarctica), where they sometimes form enormous swarms, often in deep water, and are sometimes even more abundant than krill. [5] Since 1910, while krill populations in the Southern Ocean have declined, salp populations appear to be increasing.
Giant isopods have been recorded in the West Atlantic from the US state of Georgia to Brazil, including the Gulf of Mexico and the Caribbean. [1] The four known Atlantic species are B. obtusus, B. miyarei, B. maxeyorum, and B. giganteus, and the last of these is the only species recorded off the United States.
