We've got some seriously bad news for fish-lovers. According to a report from nonprofit Oceana, over 20% of 449 fish that they tested were mislabeled, exposing some pretty serious "fish fraud." This is a staggering percentage, especially when considering that less than 1% of fish is tested for fraud. There's a huge chance that the expensive fish you're ordering while dining out is cheap - or even, according to this related Twitter thread from a biology professor, dangerous. There are fish out there that will hurt you to eat. And, as @AwesomeBioTA's class discovered, some of this "fish" is almost too disgusting for words.

With its gaping mouth, needle-sharp teeth, and slightly startled expression, the black sea devil anglerfish seems tailor-made for the spotlight.
And in fact, one particular female got her close-up on November 17 when researchers got footage of this rare anglerfish—the first time this species has been filmed alive and in its natural habitat—off of central California

With some help from a robotic fish, scientists have discovered that zebrafish are much like humans in at least one way – they get reckless when they get drunk. OK, "drunk" might not be technically accurate, but when exposed to alcohol, the fish show no fear of a robotic version of one of their natural predators, the Indian leaf fish. When they're "sober," they avoid the thing like crazy.

A clever fish has figured out that if it produces sounds in an oyster shell, the noises will carry over long distances, according to new research. The study, published in The Journal of Experimental Biology, is just the latest to show that fish are far from being silent. Many can produce sounds by vibrating their swimbladders and, like a fishy form of Morse Code, they can create different meanings based on the sounds.

A mysterious pulsating hum has been keeping people in the British town of Hythe awake at night, and scientists say there's definitely something fishy about it.
Residents have complained to the local council, saying they've had to leave the area just to sleep. Some people have even gone to the doctor, suspecting they had tinnitus.
Blame has been placed on everything from industrial noise to passing cargo ships, but the Scottish Association for Marine Science thinks it's found the answer: male midshipman fish.
The newly discovered spider called the dolomedes briangreenei hails from, you guessed it, Australia. One of it's species, whose name is Brian, was presented at the World Science Festival in Brisbane.
He was named after Professor Brian Greene, cofounder of the World Science Festival and a string theorist. 
Brian (the spider, not the string theorist) uses vibrations in the water to fish. Robert Raven, Principal Scientist of Arachnology at the Queensland Museum told Mashable:
These spiders sit there on the water and then all of a sudden an insect will hit the water and the spider races out to get it, grabs it, dives under the water and then swims back to the shore and starts eating it.
It eats insects, fish and toads up to three times it's own size. Apparently its bites aren't that dangerous but the fact remains; now even the water is not safe from spiders.

The Helicoprion was a shark-like fish that arose in the oceans of the late Carboniferous 280 million years ago, and eventually went extinct during the early Triassic some 225 million years ago.
