Glowing bacteria on deep-sea fish shed light on evolution, 'third type' of symbiosis

Wed, 18 Jul 2018 14:30:50 EDT ~ For the first time, scientists have sequenced and analyzed the genomes of bacteria that live in anglerfish bulbs. The bacteria were taken from fish specimens collected in the Gulf of Mexico. Find out more...

Fish consumption may prolong life

Wed, 18 Jul 2018 08:21:38 EDT ~ Consumption of fish and long-chain omega-3 fatty acids was associated with lower risks of early death in a new study. Find out more...

Friendlier fish may be quicker to take the bait

Mon, 16 Jul 2018 11:45:46 EDT ~ The bluegill on your dinner plate might have been more social than the rest of its group, according to a new study, and its removal from the lake could mean major changes for the remaining population. Find out more...

The secret life of lobster (trade): Could we be in hot water?

Thu, 12 Jul 2018 10:05:57 EDT ~ In today's hyper-connected world, a growing number of nations are acting as 'middlemen' in the seafood supply chain. This makes it increasingly difficult to trace where seafood goes and difficult to anticipate changes in market demand. Find out more...

Moving fish farms enables seagrass meadows to thrive, study shows

Thu, 12 Jul 2018 10:04:57 EDT ~ Off the coast of Cyprus in the Mediterranean Sea, many fish farms have been moved into deeper waters -- and on the seabeds beneath their previous locations, the meadows are flourishing once again. Find out more...

Light receptors determine the behavior of flashlight fish

Thu, 12 Jul 2018 10:04:50 EDT ~ Biologists have characterized new, unknown photoreceptors from the bioluminescent flashlight fish Anomalops katoptron. The photoreceptors known as opsins allow the fish to detect light with a specific wavelength. Scientists found new opsin variants, which are specialized to detect low intensity blue light in the wavelength range of bioluminescent light emitted by the fish. The blue light can be used to influence the fish behavior. Find out more...

Eradicate rats to bolster coral reefs

Wed, 11 Jul 2018 13:12:01 EDT ~ New research has confirmed that invasive rats decimate seabird populations, with previously unrecognized consequences for the extensive coral reefs that encircle and protect these islands. Invasive predators such as rats -- which feed on bird eggs, chicks, and even adults birds -- are estimated to have decimated seabird populations within 90 percent of the world's temperate and tropical island groups, but until now the extent of their impact on surrounding coral reefs wasn't known.

A fish that subtracts its own electric signals to better 'see' through its murky habitat

Wed, 11 Jul 2018 12:24:05 EDT ~ The elephant-nose fish Gnathonemus petersii relies on electricity to find food and navigate through the obstacles riddling its native murky African rivers. Researchers have presented evidence that the fish's ability to accurately 'see' an 'electrical image' of its surroundings requires it to filter out its own electrical interference. Find out more...

The first endemic Baltic Sea fish species received its name

Wed, 11 Jul 2018 10:56:59 EDT ~ Researchers have discovered and named a new endemic fish species in the Baltic Sea, the 'Baltic flounder,' Platichthys solemdali. Find out more...

Ancient bones reveal 2 whale species lost from the Mediterranean Sea

Wed, 11 Jul 2018 09:32:27 EDT ~ Two thousand years ago the Mediterranean Sea was a haven for two species of whale which have since virtually disappeared from the North Atlantic, a new study analyzing ancient bones suggests. The discovery of the whale bones in the ruins of a Roman fish processing factory located at the strait of Gibraltar also hints at the possibility that the Romans may have hunted the whales.
