What Is The Largest Shrimp Ever Caught

Let’s talk about shrimp. You know, the little pink curled-up things you dip in cocktail sauce at holiday parties. Well, I’m here to ruin that innocent image forever, because someone, somewhere, pulled a monster out of the ocean that looked less like a snack and more like a deep-sea dragon.

The largest shrimp ever caught wasn’t a shrimp at all in the scientific sense. It was a mantis shrimp, specifically a Lysiosquillina maculata, and it measured a jaw-dropping 18 inches long. That’s the length of your forearm. A shrimp you could use as a self-defense weapon.

First, Let’s Get the Nitty-Gritty Straight

Most people think a “shrimp” is just a tiny, pink ocean bug. Biologists, those party poopers with clipboards, will tell you that true shrimp belong to the Caridea group. But the colossal beast we’re talking about is a stomatopod—a completely different branch of the crustacean family tree.

Does that matter to us? No. If it looks like a shrimp, tastes vaguely like a shrimp, and scares you more than a shrimp, we’re calling it a shrimp for the purposes of this story. The Guinness World Records officially recognizes a 46-centimeter (18.1-inch) mantis shrimp caught in the waters of Okinawa, Japan, as the largest “shrimp” ever recorded. It was a female, by the way. Of course she was—bigger, stronger, and probably annoyed at being measured.

A Shrimp That Could Punch Through Glass

Here’s where it gets hilariously terrifying. This wasn’t just a big shrimp; it was an arsenal. Mantis shrimp have two specialized appendages called dactyl clubs. They use them like biological jackhammers to smash open crab shells. The strike is so fast it vaporizes water, creating cavitation bubbles that generate a second shockwave.

Seriously. This shrimp punches at 50 miles per hour with the force of a .22 caliber bullet. If this giant mantis shrimp had tiny little boxing gloves, it could knock out a goldfish from three feet away. Aquariums literally have to keep them in plastic tanks because they crack glass for fun.

Could You Eat It?

Let’s answer the only question that matters: would you put this thing on a grill? Technically, yes. People do eat mantis shrimp in parts of Asia. But imagine trying to wrestle an 18-inch, bullet-punching crustacean onto a plate.

You’d need a flamethrower and a suit of armor. And once cooked, the meat is reportedly sweet and delicious, like a cross between lobster and crab. But you’d be eating a creature that could have punched your hand off five minutes earlier. That’s a power dinner.

The Runner-Up: A True Monster

If you insist on a “true” shrimp from the Caridea family, the record goes to a beast known as Heterocarpus ensifer or something similarly boring. But the real champ among regular shrimps is the tiger prawn.

In 2014, a fisherman off the coast of Alabama pulled up a tiger prawn that was 13 inches long and weighed nearly a pound. That’s the size of a small cat. A meaty cat. It’s also an invasive species, likely escaping from a flooded aquaculture farm, so it was basically a fugitive shrimp on the run.

Why Don’t We See Giant Shrimp at Red Lobster?

Simple: money and logistics. Giant shrimps are usually individuals that have avoided death for a very long time. To catch a mantis shrimp that size, you need specialized traps, a strong net, and a willingness to possibly lose a finger.

Plus, the big ones are territorial loners. They don’t swim in schools like pathetic little cocktail shrimps. They sit in burrows on the ocean floor, plotting their next punch. Commercial fishing boats don’t want to deal with that attitude. They want the hundreds of tiny, cooperative shrimp that don’t try to break the boat in half.

The Visual You Can’t Unsee

Imagine this: you’re snorkeling in Okinawa. The water is clear. You see a beautiful, colorful creature with iridescent green spots and bright red claws. You think, “Oh, pretty!

Then it turns to look at you. Its eyes—which have 16 types of photoreceptor cells (we have three)—are mounted on stalks that move independently. It sees colors you cannot even imagine. It perceives your soul. And in that moment, you realize: you are not the top predator here. You are just prey with a snorkel.

The Takeaway

The largest shrimp ever caught is a 48-centimeter mantis shrimp, a creature that could break your thumb, see into ultraviolet dimensions, and would cost you $200 at a fancy sushi bar. It’s a delicious nightmare.

So next time you peel a little pink shrimp at a buffet, take a moment to respect it. That tiny, curved body is just a baby version of a pugilistic ocean gladiator. And somewhere, in a hole off the coast of Japan, its 18-inch cousin is waiting to punch its way into the record books again.

Just don’t order it with cocktail sauce. You’ll need a stronger dip. Like concrete.
