The American pocket shark is the only known specimen of its kind to have ever been found. By Samantha Stocks.
The tiny shark, named the American pocket shark, was collected by chance in by a research team aboard a NOAA ship studying sperm whale feeding off the Gulf of Mexico. The shark was sent to the Tulane University Biodiversity Research Institute in for further investigation, where it was compared to a pocket shark found off the east coast of Chile — the only other similar specimen to have been found.
The original pocket shark was found in and was described as a new species in Until the American pocket shark was identified, it was the only pocket shark known to science.
Both species are types of kitefin shark, but with five key differences that classifies them as being separate species. Though both have small pocket glands behind each pectoral fin on either side of the body, the glands of American pocket shark produce a bioluminescent fluid, and photophores light producing organs cover much of its body, enabling it to glow in the dark.
Details of the American pocket shark are described in Zootaxa. Home News Scientists discover new shark species that glows in the dark.

I noticed that it seemed to tug on my face a bit more than the blades that I normally use. I didn't get any bleeders, but my AS gave me a bit more sting than normal. Overall, the shave wasn't as smooth as I would have liked, and didn't give me BBS after 3 passes on my neck. I'll give it another try tonight, but if it gets any worse, I'll switch it out. Nice review. Sharks work pretty well for me. They are two different blades I have a couple Super Chrome to give a try as well as the Lord line of the same blades.
Joe blow. I'm not a champion of these blades, but there is certainly nothing wrong with them, use them once, throw them out, they work great Bookworm said:. The Shark SS was my first blade buy. The blades are a good choice for the beginner which I was. I noticed that I can usually get shaves before the blade dulls. For the person that asked - They're supposedly Super Chrome, but here's a picture of the wrapper and the printing on the blade.
As you can see, they're Super Chrome Super Stainless. Thanks Bookworm It looks as though the one you have are the Super Chrome. I believe the blade itself is stainless but the edge on it and the plating is chrome. Yours is the 1st I've seen that have both stamped on the blade though I thought it was rather confusing, myself. Maybe they're trying to convince people they only have one line of blades?
Ironic I would see this post today. I was traveling overnight and this morning I used a Shark Chrome with a couple shaves on it that was in my travel kit with a pre-war Tech.
A nice, mild, and efficient shave. Bookworm How are you getting on with the Super Chrome blades? I have been testing one in my 37C, which I used this morning , and am 4 shaves in on it and am finding it to be pretty much in line with my experiences of the Super Stainless blades that I purchased of a while back I normally get really smooth shaves out of the SS blades and wondering if I will get the same from the SC Anyway, my very smooth shave this morning reminded me of this thread and was just wondering if you had any other thoughts to add from the original post?
Sorry for note updating. I did do another shave with the blade, and it was okay, but not quite as good as the first. That might more have been me than anything else. I'll try another one later, but I need to work through some of the variety of others I'm testing out. I think I have another 15 to test. I am a fan of the Shark blades. Either one. They give me a BBS shave with 3 passes. No irritation, just buttery smoothness. Dog Whiskerer.

Greenland sharks are absurdly slow and mostly blind, yet they may have spread far beyond the Arctic waters they are known from. They can be as big as great white sharks, but that's about as far as the comparison goes. Their maximum speed is a lethargic 1. They may be common throughout the ocean, but you've probably never heard of them. Meet the Greenland shark. Looking like nothing so much as a chunk of weather-beaten rock, Greenland sharks Somniosus microcephalus can grow up to 7.
But they prefer to live in deep, cold water, so humans rarely see them. Studies in the Arctic have revealed a few snippets of information about Greenland sharks, and more data is now starting to come in from elsewhere. It turns out that Greenland sharks are bizarre, and may be crucially important for the ocean ecosystem.
They are most easily seen around Greenland and Iceland. As a result, they were long thought of as purely polar animals, as were the closely-related Pacific sleeper shark and southern sleeper shark. Some researchers think they live in many other areas too but just haven't been spotted in them yet. The obvious way to see a Greenland shark in the wild is to dive into the deep sea. For instance, in a remotely operated vehicle in the Gulf of Mexico captured footage of either a Greenland shark or a sleeper shark in over 2, metres 8,ft of water.
Two years later, a pilot and a scientist from the Harbor Branch Oceanographic Institution in Fort Pierce, Florida, became the first people to come face to face with a Greenland shark in the deep sea.
The shark, which was five metres 16ft long, bumped into their submersible vessel 1, metres 3,ft down in the Gulf of Maine. But hardly anyone dives that deep. So these rare encounters can't tell us how widespread and important the Greenland sharks are. However, if the history of fishing is any guide, Greenland sharks are common as muck. The sharks were fished from the early 20th century until the s; mainly for their liver oil, which was used as lamp fuel and industrial lubricant.
In some years, over 30, were taken. That suggests a very healthy population. In line with that, a recent expedition used hooks on a longline, and caught 59 sharks. So what are all these Greenland sharks eating? To find out, scientists have to get their hands dirty - by cutting open the sharks' stomachs and pulling out the remains of their meals.
So far this kind of work suggests the menu of the Greenland shark is highly varied. As well as fish, they eat just about anything that might fall off the ice, including reindeer and polar bears.
Given a chance it seems they will even try to eat moose. Last November, a man in Newfoundland found a Greenland shark gagging on a piece of moose hide, which had probably been thrown into the water by a hunter. He and another man decided to save the shark from choking on the hunk of moose. It seems the sharks aren't too concerned about the freshness of their meals. Researchers have found small crustaceans called amphipods in their stomachs. These critters swarm over dead bodies in deep waters, so finding them hints that the sharks sometimes eat carrion.
View image of "My eye! It's on my eye! That would make sense, because it's hard to understand how a Greenland shark could ever catch living prey. For one thing they are absurdly slow, moving more sluggishly than any other shark. One satellite tagging study found that they usually meander about at around 0. Others say they can reach 2. Regardless, many of the things they might want to eat can swim faster.
If that wasn't enough, many Greenland sharks appear to be almost blind. The shark that rammed the Harbor Branch submersible had them dangling from its eyes. So how do Greenland sharks catch anything? It has been suggested that the parasitic crustaceans might be bioluminescent , and that the light they give off attracts fish for the shark. He says the scientific literature on the sharks is "contaminated" with unsubstantiated claims like this.
Benz thinks the sharks are more likely to be ambush predators. For example, Arctic seals sometimes sleep in the water to avoid polar bears, potentially allowing Greenlands to sneak up on them. The seals also have to poke their heads through ice holes to breathe, giving the sharks an opportunity to catch them unawares. No one has directly observed Greenland sharks catching seals in this way, but there is some circumstantial evidence.
Large numbers of dead seals with "corkscrew" wounds have been recovered at Sable Island off the coast of Nova Scotia. Some were bitten in half, while others had the skin and blubber stripped from the lower halves of their bodies. Others are unconvinced, arguing the seals were chopped up by propeller blades. Whether or not the Greenland shark is the "Corkscrew Killer", Fisk has evidence that the species eats seals aplenty. He knew that seals in Svalbard have a short average lifespan despite seemingly ideal conditions: humans don't hunt them, they have few known predators, they aren't being accidentally caught by fishermen, and the area is not polluted.
Wondering what was killing the seals, his team carried out stomach analyses on 45 Greenland sharks, and found that about a third contained the remains of seals. That was enough to explain the shorter lifespans. View image of Even belugas Delphinapterus leucas may be on the menu Credit: E. Fisk's stomach analyses showed that they eat the discarded leftovers from Norwegian whale hunts.
And it's not just dead whales they'll go after. Fisk has photographs of a group of beluga whales that came to a grisly end after becoming trapped by shifting ice off Baffin Island, northern Canada. All this suggests Greenland sharks are playing a big role in the Arctic food web.
If they are as common as everyone now suspects, they would have a big impact on other animals, says Fisk. That may also be true in their deeper habitats, even if they get most of their food from sinking corpses. Benz says the sharks could be helping provide food for a wide range of other animals by breaking up these larger chunks of flesh. If Greenland sharks are so important to the waters they live in, it would be good to know what is going to happen to them. However, fishing seems unlikely to pose a major threat to the sharks.
For one thing their meat is toxic, because it is rife with unsavory organic contaminants. So Greenland sharks are not regarded as a good dining option. In , a group of sled dogs was fed Greenland shark flesh. Reportedly they were left walking stiffly, hyper-salivating and vomiting - not to mention having muscular convulsions, respiratory distress, and explosive diarrhoea. Some died. The meat is detoxified through a multi-week rotting process. Others have described it as a contender for the most disgusting food on the planet.
It probably won't catch on enough to threaten the species. Fishermen might catch the sharks by accident, though. From the late s, the Inuit returned to fishing for Greenland halibut as a means of preserving their culture. Greenland sharks try to snatch free meals from the fishing hooks, and can get wrapped up in the lines. Coast Guard, CC by 2.
That leaves climate change. Perhaps its most dramatic effect is the rapid retreat of the Arctic sea ice, particularly in the summer. What will that mean for the sharks? As the summer ice levels decrease, the window for fishing grows larger. So while the halibut fishing has been limited so far, that could soon change. Large commercial fishing operators are well aware of this opportunity.
But the effects of the retreating ice go far beyond a few fishing boats. The entire Arctic ecosystem revolves around the sea ice. For the Greenland sharks, ice acts as a food delivery device.
It's what keeps seals over open water, and as it melts it delivers dead animals as potential meals. That food source could be drastically cut as the ice shrinks ever further.
But other animals, particularly fish from further south, are migrating into the Arctic. Might the Greenland sharks start eating them? As so little is known about the sharks, it's difficult to say what will happen. All we can say for sure is that the Greenland sharks will be living in a very different Arctic in a few decades' time.
