Meet the Mantis Shrimp: The Ocean’s Technicolor Boxing Champion

If you crossed a heavily armored tank, a kaleidoscopic rainbow, and a professional heavyweight boxer, you would get the mantis shrimp. These aggressive, highly intelligent crustaceans are easily one of the most ridiculous and fascinating creatures in the sea.

Here is everything you need to know about the ocean’s most beautifully dangerous resident.

1. They Punch with the Speed of a Bullet

Mantis shrimp do not play with their food (mainly small fish, molluscs, and other crustaceans)—they obliterate it. Depending on the species, they are equipped with one of two built-in weapons on their second pair of legs:

• The “Spearers”: Armed with spiny, barbed claws used to impale prey like a kabob.
• The “Smashers”: Armed with club-like appendages used to literally batter their targets into submission.

The smashers are famous for striking with an acceleration of up to 23 meters per second—roughly the speed of a .22 caliber bullet. But the physical punch is only half the problem. They hit so hard and fast that the water around their claws vaporizes. This creates a cavitation bubble that immediately implodes, producing a sharp bang, intense heat, and a literal flash of light. Even if the shrimp misses, the resulting shockwave is enough to stun or kill their prey. Unsurprisingly, these guys have been known to shatter aquarium glass!

2. The Most Over-Engineered Eyes in the Animal Kingdom

Their boxing skills are impressive, but their eyesight is basically alien technology. They possess arguably the most complex eyes in the entire animal kingdom.

Their eyes sit on stalks and operate completely independently, giving them a massive, 360-degree view of their surroundings. Even wilder: each individual eye is divided into three parts, meaning a mantis shrimp has depth perception in just one eye (trinocular vision).

Scientists believe this hyper-advanced vision serves a few very specific, highly awesome purposes:

• Secret Spy Communication: They can see polarized light, allowing them to send secret signals to other mantis shrimp that clueless predators can’t intercept.
• Seeing the Invisible: Their UV vision acts like a cheat code to spot camouflaged prey hiding on coral reefs.
• Lunar Romance: They glow with special fluorescent colors during mating that match what their eyes can see. They might even use their vision to track the phases of the moon to perfectly time their reproduction.
• Outsourcing Brain Work: Processing all these colors normally takes a lot of brainpower. Instead, the mantis shrimp’s eyes do the “thinking” first. This hardware shortcut allows them to react at lightning speed, which is incredibly handy when you’re a highly territorial fighter.

3. Lovers, Fighters, and Cartwheelers

Despite their violent hunting methods, mantis shrimp are surprisingly highly intelligent and social creatures. They have a great capacity to learn, retain knowledge, and even recognize their neighbors. They exhibit complex behaviors like ritualized fighting (essentially an underwater Fight Club) and protective activities.

When it comes to romance, some of them are absolute players, mating up to 30 times over their lifespan. Others, however, are monogamous and will mate for life. The female lays the eggs and keeps them safe in burrows or under her tail. Depending on the species, both parents will share babysitting duties, or the male will go out to hunt while the female stands guard. Once the babies hatch, they spend three months floating around as plankton before leveling up into full-fledged punchers.

Oh, and if all of this wasn’t weird enough: while they usually move like typical crustaceans, there is one specific species of mantis shrimp known to casually travel by doing cartwheels.

4. The XXL Edition

Think these are just tiny, inch-long aquarium oddities? Think again. While many are small, the largest recorded mantis shrimp was a terrifying 46 centimeters (18 inches) long. Imagine a foot-and-a-half-long crustacean swinging sledgehammers at you. No thank you!
