The killer punch of the mantis shrimp is the fastest strike in the animal kingdom, a skill that goes hand in hand with its extraordinary eyesight. They can see an invisible level of reality using polarized light, which could lead to a breakthrough in detecting cancer.

Aggressive, reef-dwelling mantis shrimp take more than one first-place ribbon in the animal kingdom. Outwardly resembling their lobster cousins, their colorful shells contain an impressive set of superpowers.
There are two types of mantis shrimp, named for their attack mode while hunting prey: smashers and spearers. With their spring-loaded, weaponized legs, these predators can crack a snail shell or harpoon a passing fish in a single punch.
The speed of these attacks has earned the mantis shrimp one of their world records: fastest strike in the animal kingdom.
Scientists are finding that another of their special abilities -- incredible eyesight -- has potential life-saving implications for people with cancer.
Mantis shrimp can perceive the most elusive attribute of light from the human standpoint: polarization. Polarization refers to the angle that light travels through space. Though it’s invisible to the human eye, many animals see this quality of light, especially underwater.
But mantis shrimp can see a special kind of polarization, called circular polarization. Scientists have found that some mantis shrimp species use circular polarization to communicate with each other on a kind of secret visual channel for mating and territorial purposes.
Inspired by the mantis shrimp’s superlative eyesight, a group of researchers is collaborating to build polarization cameras that would constitute a giant leap for early cancer detection. These cameras see otherwise invisible cancerous tissues by detecting their polarization signature, which is different between diseased and healthy tissues.
--- How fast is the mantis shrimp punch?
Their strike is about as fast as a .22 caliber rifle bullet. It’s been measured at 50mph.
--- What do mantis shrimp eat?
The “smasher” mantis shrimp eat hard-shelled creatures like snails and crabs. The “spearers” grab fish, worms, seahorses, and other soft-bodied prey by impaling them.
--- Where do mantis shrimp live?
In reefs, from the east coast of Africa to the west coast of Australia, and throughout Indonesia. A few species are scattered around the globe, including two in California.

Every spring, keen-eyed biologists carrying fishing poles search the rolling hills near Los Banos, about two hours south of San Francisco. But they’re not looking for fish. They’re catching rock-paper-scissors lizards.
The research team collects Western side-blotched lizards, which come in different shades of blue, orange and yellow.
Barry Sinervo, a professor of ecology and evolutionary biology at UC Santa Cruz, leads the team. Their intricate mating strategies reminded the the researchers of the rock-paper-scissors game where rock beats scissors, scissors beats paper and paper beats rock.
It’s all about territories. Orange males tend to be the biggest and most aggressive. They hold large territories with several females each and are able to oust the somewhat smaller and less aggressive blues. Blue males typically hold smaller territories and more monogamous, each focusing his interest on a single female. Yellow males tend not to even form exclusive territories Instead they use stealth to find unaccompanied females with whom to mate.
The yellow males are particularly successful with females that live in territories held by their more aggressive orange competitors. Because the orange males spread their attention among several females, they aren’t able to guard each individual female against intruding yellow males. But the more monogamous blues males are more vigilant and chase sneaky yellow males away.
Their different strategies keep each other in check making the system stable. Sinervo believes this game has likely been in play for at least 15 million years.
--- How do side-blotched lizards choose a mate?
The males compete with each other, sometimes violently, for access to females. The females generally prefer males of their own color but also give preference to whichever color male is more rare that mating season.
--- Why do lizards do push up and down?
Male lizards do little pushups as a territorial display meant to tell competitors to back off. It’s best to use a warning instead of fighting right away because there’s always a danger of getting hurt in a fight. Some lizards like side-blotched lizards also use slow push ups to warn their neighbors of an incoming threat.
--- Why do side-blotched lizards fight?
Sometimes aggressive territorial displays are not enough to dissuade invaders so side-blotched lizards will resort to fighting. They have small sharp teeth and will lunge at each other inflicting bites and headbutts.

Cone Snails have an arsenal of tools and weapons under their pretty shells. These reef-dwelling hunters nab their prey in microseconds, then slowly eat them alive.

DEEP LOOK is a ultra-HD (4K) short video series created by KQED San Francisco and presented by PBS Digital Studios. See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small.
New research shows that cone snails — ocean-dwelling mollusks known for their brightly colored shells — attack their prey faster than almost any member of the animal kingdom.
There are hundreds of species of these normally slow-moving hunters found in oceans across the world. They take down fish, worms and other snails using a hollow, harpoon-like tooth that acts like a spear and a hypodermic needle. When they impale their prey, cone snails inject a chemical cocktail that subdues their meal and gives them time to dine at their leisure.
Cone snails launch their harpoons so quickly that scientists were previously unable to capture the movement on camera, making it impossible to calculate just how speedy these snails are. Now, using super-high-speed video, researchers have filmed the full flight of the harpoon for the first time.
From start to finish, the harpoon’s flight takes less than 200 micro-seconds. That’s one five-thousandth of a second. It launches with an acceleration equivalent to a bullet fired from a pistol.
So how do these sedentary snails pull off such a high-octane feat? Hydrostatic pressure — the pressure from fluid — builds within the half of the snail’s proboscis closest to its body, locked behind a tight o-ring of muscle. When it comes time to strike, the muscle relaxes, and the venom-laced fluid punches into the harpoon’s bulbous base. This pressure launches the harpoon out into the snail’s unsuspecting prey.
As fast as the harpoon launches, it comes to an even more abrupt stop. The base of the harpoon gets caught at the end of the proboscis so the snail can reel in its meal.
The high-speed action doesn’t stop with the harpoon. Cone snail venom acts fast, subduing fish in as little as a few seconds. The venom is filled with unique molecules, broadly referred to as conotoxins.
The composition of cone snail venom varies from species to species, and even between individuals of the same species, creating a library of potential new drugs that researchers are eager to mine. In combination, these chemicals work together to rapidly paralyze a cone snail’s prey. Individually, some molecules from cone snail venom can provide non-opioid pain relief, and could potentially treat Parkinson’s disease or cancer.
--- Where do cone snails live?
There are 500 species of cone snails living in the Indian and Pacific Oceans, the Caribbean and Red Seas, and the Florida coast.
--- Can cone snails kill humans?
Most of them do not. Only eight of those 500 species, including the geography cone, have been known to kill humans.
--- Why are scientists interested in cone snails?
Cone snail venom is derived from thousands of small molecules call peptides that the snail makes under its shell. These peptides produce different effects on cells, which scientists hope to manipulate in the treatment of various diseases.

Kidnapper ants raid other ant species' colonies, abduct their young and take them back to their nest. When the enslaved babies grow up, the kidnappers trick them into serving their captors – hunting, cleaning the nest, even chewing up their food for them.

DEEP LOOK is a ultra-HD (4K) short video series created by KQED San Francisco and presented by PBS Digital Studios. See the unseen at the very edge of our visible world. Explore big scientific mysteries by going incredibly small.
A miniature drama is playing out on the forest floor in California’s preeminent mountain range, the Sierra Nevada, at this time of year. As the sun sets, look closely and you might see a stream of red ants frantically climbing over leaves and rocks.
They aren’t looking for food. They’re looking for other ants. They’re kidnappers.
“It’s hard to know who you're rooting for in this situation,” says Kelsey Scheckel, a graduate student at UC Berkeley who studies kidnapper ants. “You're just excited to be a bystander.”
On this late summer afternoon, Scheckel stares intently over the landscape at the Sagehen Creek Field Station, part of the University of California’s Natural Reserve System, near Truckee, California.“The first thing we do is try to find a colony with two very different-looking species cohabitating,” Scheckel says.
“That type of coexistence is pretty rare. As soon as we find that, we can get excited.”
--- How do ants communicate?
Ants mostly use their sense of smell to learn about the world around themselves and to recognize nestmates from intruders. They don’t have noses. Instead, they use their antennae to sense chemicals on surfaces and in the air. Ants’ antennae are porous like a kitchen sponge allowing chemicals to enter and activate receptors inside. You will often see ants tap each other with their antennae. That behavior, called antennation, helps them recognize nestmates who will share the same chemical nest signature.
---Can ants bite or sting?
Many ants will use their mandibles, or jaws, to defend themselves but that typically just feels like a pinch. Some ants have a stinger at the end of their abdomen that can deliver a venomous sting. While the type of venom can vary across species, many ants’ sting contains formic acid which causes a burning sensation. Some have special glands containing acid that can spray at attackers causing burning and alarming odors.
