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.

A new type of bee is buzzing through California's orchards. And researchers are hoping that the iridescent, greenish insect may help provide a more efficient way to pollinate nuts and fruits in an era when traditional honeybees have struggled.

Unlike honeybees, blue orchard bees don’t sting humans. And instead of building large colonies with thousands of worker bees caring for eggs laid by a queen bee, female blue orchard bees work alone to build their nests and stock them with food. They’re solitary bees, like most of the 4,000 species of bees in North America.

Blue orchard bees, which are native to the United States, are of increasing interest to scientists, government agencies and farmers for their ability to pollinate almonds, sweet cherries and other tree fruits more efficiently than honeybees.

“This is, I think, the moment for these bees to shine,” said entomologist Natalie Boyle, who studies blue orchard bees at the United States Department of Agriculture in Logan, Utah.

Boyle works with almond growers in California, whose crop is worth $5.2 billion a year and who rely heavily on honeybees to pollinate their orchards every February. Research has found that 400 female blue orchard bees are as effective at pollinating almonds as the more than 10,000 bees in a honeybee hive, said Boyle.

Between 40 and 50 percent of honeybee colonies die each year around the country, according to the yearly National Honey Bee Survey, carried out by universities with the sponsorship of the USDA and the California Almond Board, among others.

Finding other bees that could work side by side with honeybees could offer what Boyle calls “pollination insurance.”

--- What is a mason bee?
The blue orchard bee is a mason bee. Females build their nests out of mud that they collect with two huge pincer-like tools on their face called mandibles. In nature, they build their nests in places like hollow twigs. But they will also build them in pencil-wide drill holes in a wood block.

--- What makes blue orchard bees good pollinators?
One thing that makes blue orchard bees good pollinators are hairs on their abdomen called scopa, on which they collect and spread pollen. Blue orchard bees are particularly good at pollinating almonds and tree fruits like cherries and apples because they love foraging in their flowers. And they’re particularly well-suited to pollinate almonds, which are in bloom in February, when it’s chilly in California’s Central Valley, because they will fly around and forage at a cooler temperature than honeybees.

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.

--- How do some insects breathe underwater?

Air-breathing aquatic bugs and beetles don’t hold their breath the way sea mammals do, nor do they have gills like fish.

So how do they do it? The answer lies in their small size. Insect scuba strategies hinge on a property of water that relative giants like us usually overlook: surface tension.

People first crossed the line between land and sea to become scuba divers more than 70 years ago, when Jacques Cousteau pioneered the Aqua-Lung in Nazi-occupied France.

But some species of aquatic insects have been doing it for millions of years.

“Water beetles have been breathing underwater since before the dinosaurs existed,” said Crystal Maier, an entomologist at The Field Museum in Chicago. “It has evolved at least 10 times across the insect tree of life.”

--- What is surface tension?

Surface tension is the property of any liquid that describes how its particles stick together. In the case of water, surface tension is especially strong, enough to form a kind of film where it meets the air, whether at the surface or in a bubble.

The film is so strong, in fact, that a paper clip, which should sink because of its density, will float.

Surface tension is a delicate force, vulnerable to changes temperature, turbulence or the introduction of contaminants, like soap. A sudden drop in surface tension can drown a whole insect community in an instant.

Though it might not seem to affect our world to the same degree, surface tension is active all around us. It allows raindrops to form, trees to bring water to their leaves and ice to float. So in a sense, we too live on a thin boundary, ruled by the same subtle properties of water.

--- How do beetles use surface tension to breathe underwater?

If you’re a bug the size of a paperclip, in other words, surface tension makes a difference. Harnessing it, some aquatic beetles carry the oxygen they need underwater in the form of a temporary bubble, sort of like a natural scuba tank. Others encase themselves in a layer of air and draw oxygen from it their whole lives.

“It’s a pretty successful group of insects. They’re on every continent, except Antarctica,” said Cheryl Barr, collection manger emeritus at the Essig Museum of Entomology at UC Berkeley.
