Rare Goblin Shark Caught in Gulf of Mexico

Commercial fisher Carl Moore wasn’t sure what he had netted last week just south of Key West, Florida (map), when he saw the fish’s flat, blade-like snout. Only after the Georgia angler photographed and released his catch was its identity confirmed: It was a goblin shark, a rare deep-sea shark, and it’s believed to be only the second such specimen ever caught in the Gulf of Mexico.

These sharks are so rarely encountered that any information about them is eagerly devoured by researchers, says John Carlson, a research biologist for the U.S. National Oceanic and Atmospheric Administration (NOAA) Fisheries Service. After Moore examined his curious catch and took a series of photos of it, he released it back into the ocean and contacted NOAA. Moore’s photos were referred to Carlson, who specializes in sharks and was excited to get more data on this rare one.

“We don’t know how long they live; we don’t know how often they reproduce, or even how big they are when they reproduce,” Carlson says. “They’re a mystery.”

Moore had told NOAA he thought the shark he released was about 18 feet (5.4 meters) long. When Carlson and colleagues analyzed Moore’s photographs, they gauged the length to be more like 15 feet (4.5 meters) long. And they made an educated guess about the shark’s sex.

Carlson says male sharks have external sexual characteristics called claspers, two fin-like appendages near the tail that males use to hold on to females while mating. “From the photographs, we don’t see those, so we’re suspecting it’s a female,” he says.

Life in the Dark

Moore caught the goblin shark at around 2,000 feet (610 meters) deep. That’s on the shallower end of the average depth range for this species, Carlson says: They’re usually found between 2,000 and 3,000 feet (610 and 914 meters) deep. That makes it one of the deepest occurring species among sharks and their relatives—and many of the shark’s unusual features probably are adaptations to its habitat, he says. (Read about other animals with weird snouts.)

Sharks have a series of sensors in their head called ampullae of Lorenzini, which enable them to pick up the electrical signals of animals around them. The goblin shark’s unusually shaped head may provide an advantage in the gloomy deep, Carlson says, as the distribution of those sensors along the long, flat blade would extend the radius in which the sharks could detect prey. ”It’s the same sort of thing with hammerhead sharks,” he says, with the ampullae found along the edge of the animal’s distinctively shaped head.

Once a goblin shark locates its prey, that’s where its needle-like teeth come in. Carlson says the teeth act like knives, impaling and holding on to soft-bodied prey such as fish and squid.

Shrouded in Mystery

The first recorded appearance of a goblin shark in the Gulf of Mexico was fairly recent, in 2000. Before that, the last time anyone reported seeing a goblin shark in the North Atlantic was in the 1970s off the Bahamas, says Carlson.

They’ve been found in the waters off Brazil, French Guiana, Colombia, and the Indo-Pacific, but ”probably 80 percent of known records [of these sharks] occur off Japan,” the research biologist says. (See “Rare ‘Prehistoric’ Goblin Shark Caught in Japan.”)

Carlson and colleagues are working on a paper describing this latest goblin shark sighting in the Gulf of Mexico, and are trying to figure out if there are hot spots for this animal around the world. The scientists aren’t sure whether goblin sharks are just more abundant around Japan or if the lopsided sightings are a consequence of uneven sampling by researchers.

To build his knowledge of goblin sharks, Carlson says, he would have loved to have seen the specimen Moore pulled up. But he’s glad that Moore was able to release it alive, to resume its mysterious life in the deep.

    sharks and most fish are known to blend with their environment ,the brown color doesnt meant the goblin is dead but keeping it out of water for a long while without keeping it wet will make it lose its slime and surely die. even if it doesnt die immediately,it would be prone to infections.Moreover,hanging it upside down would kill it within a short while.

    Clearly the sharks intestines would have fallen out of his mouth when they put it upside down. The shark is dead, another piece of by-catch.

    They said this type of shark is still rare, what’s the color matter? We don’t have all the facts on this type of shark yet. Why accuse this man of killing a rare breed shark? I’m pretty positive if the shark was dead they would have kept it, maybe make money off it, maybe have an article written about them catching the shark in Nat geo. Endless possibilities of what they could have done with the rare shark breed. But instead, he released it. The shark was probably stunned that it got dragged up in a net. Just because a still picture doesn’t show the sharks movements, it doesn’t mean it’s dead.

    it should be called an Alien shark, or Area 51 Shark, maybe it looks dead in the picture because it never had its picture taken before, and give the fisherman a break, he is hunting shrimp not Goblins.

Ok I jest about the baby seal but the ‘outrage’ over the death of the shark is pathetic considering the number of things killed on your behalf daily, including clothing, food, makeup, etc..

    I agree that Shark is long gone. Not only did that idiot hang it upside down ( who wouldn’t that kill?) but he also caught it in a fishing net. So common logic will tell you that the shark was immobile for some part of time which means death for a shark. and sorry but if you caught something that rare. Would you catch and release? I think not.

    this is what I think:
    1.the shark is dead
    2.based on a previous comment from the author of this article there was no pics of the shark being released
    3.sharks are brown after being preserved in alcohol
    4.hanging sharks like that kills them

    its dead.

    Yes, a living being that was pulled up from 2000 feet under water is still alive and just swam right back down. Do people hear themselves talk? Do you realize the pressure change involved? The weight of water? Of course, the ones making these comments are the same ones who say hunting and fishing is bad. Why can’t you just buy your meat from the store and not participate in such savagery?

    Sharks and Skates are two animals that can survive the massive pressure changes from depths. meaning the shark was probably alive when it came up out of the water.

    They bring Squid up from the very deep and they live. So I think the Shark may have survived this. And for being in a net and drowning doubt it there is water going through the gills from the motion of the net being brought up!

    This responsible fisherman didn’t have to share this information with anybody, but he chose to record the data and report the interaction with an endangered species. Well done! With that in mind, if it was dead, it is logical to assume that the shark would have been put on ice for the researchers.

    First of all, the goblin shark is alive, just because it’s upside down, doesn’t mean that it’s dead. And it does not have ‘bright colors’ when it’s alive, it’s brown. There would be no point in a -2000 foot sea level predator, to be bright colors. And the reason why nobody cares about the shrimp, is because their lives don’t matter as much to us a bigger animal. They don’t have as much of an impact. They don’t know the difference between human and shark. Their is practically no soul leaving this earth, when it dies.

    I believe they released it back to the water. To those people looking for photos showing the release, sharks aren’t like dolphins, especially that goblin shark. The people who caught it weren’t like some of us who like to take pictures of everything (selfies as examples).

    Looks dead hanging limply. Would shark suffocate to death in a shrimp net? With the late annoucement of the find, the ‘released it back’ story sounds like a cover to keep the shark; stuff and preserve it. Sell it on perhaps?

    I agree with many of you about the status of this shark: It’s dead, even before reaching the deck of the boat. Even if it could be alive for 1 or 3 minutes. The fisherman intentions maybe were good. He tried to release the shark on time. We can not be sure about it

    I am curious what the implications are of bringing the shark from 2000 ft to the surface and then leaving it on deck long enough for staging and photos. Is it possible that it could survive those pressure changes and return to depth?

  61. Jane J. Lee

    May 6, 9:45 am

    I’m not sure why this particular goblin shark looks more brown than pink. NOAA researcher John Carlson did mention that they’re usually pink.

    As for barotrauma, I asked about that. Carlson said that since goblin sharks don’t have swim bladders, that’s one less thing to worry about re getting pulled up from the depths too quickly.

    He said the fisher (Moore) described the shark as being very active on deck. Moore wanted to measure the shark, but because it was moving around so much and the teeth looked pretty scary, he didn’t want to approach the animal.
