These Lizards Have Been Playing Rock-Paper-Scissors for 15 Million Years | Deep Look

Male side-blotched lizards have more than one way to get the girl. Orange males are bullies. Yellows are sneaks. Blues team up with a buddy to protect their territories. Who wins? It depends - on a genetic game of roshambo.

* NEW VIDEOS EVERY OTHER TUESDAY! *

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.

Turret Spiders Launch Sneak Attacks From Tiny Towers | Deep Look

There are strange little towers on the forest floor. Neat, right? Nope. Inside hides a spider that's cunning, patient and ruthless.

Most Bay Area hikers pass right by without ever noticing, but a careful eye can spot tiny towers rising up from the forest floor. These mysterious little tubes, barely an inch high, are the homes of a particularly sneaky predator -- the California turret spider.

“To me, the turrets look just like the rook in a chess set,” said Trent Pearce, a naturalist for the East Bay Regional Park District, as he scanned the terrain at Briones Regional Park. “The spiders themselves are super burly – like a tiny tarantula the size of your pinky nail.”

Turret spiders build their towers along creek beds and under fallen trees in forested areas throughout Central and Northern California. They use whatever mud, moss, bark and leaves they can find nearby, making their turrets extremely well camouflaged.

They line the inside of their tiny castles with pearly white silk, which makes the structure supple and resilient

Each turret leads down to a burrow that can extend six inches underground. The spiders spend their days down there in the dark, protected from the sun and predators.

As night falls, they climb up to the entrance of the turrets to wait for unsuspecting prey like beetles to happen by.

Turret spiders are ambush hunters. While remaining hidden inside their turret, they’re able to sense the vibrations created by their prey’s footsteps.

That’s when the turret spider strikes, busting out of the hollow tower like an eight legged jack-in-the-box. With lightning speed the spider swings its fangs down like daggers, injecting venom into its prey before dragging it down into the burrow.

“It’s like the scene in a horror movie where the monster appears out of nowhere – you can’t not jump,” Pearce said.

--- What do turret spiders eat?
Turret spiders mostly ground-dwelling arthropods like beetles but they will also attack flying insects like moths that happen to land near their turrets.

--- Are turret spiders dangerous to people?
Turret spiders are nocturnal so it’s rare for them to interact with humans by accident. They tend to retreat into their underground burrow if they feel the vibrations of human footsteps. They do have fangs and venom but are not generally considered to be dangerous compared to other spiders. If you leave them alone, you shouldn’t have anything to fear from turret spiders.
