--- Why do Jellyfish Sting?
Jellyfish sting to paralyze their prey. They use special cells called nematocysts. Jellyfish don’t have a brain or a central nervous system to control these stinging cells, so each one has it’s own trip wire, called a cnidocil.
When triggered, the nematocyst cells act like a combination of fishing hook and hypodermic needle. They fire a barb into the flesh of the jellyfish’s prey at 10,000 times the force of gravity – making it one of the fastest mechanisms in the animal kingdom. As the barb latches on, a thread-like filament bathed in toxin erupts from the barb and delivers the poison.
The nematocyst only works if the barb can penetrate the skin, which is why some jellies are more dangerous to humans than others. The smooth-looking tentacles of a sea anemone (a close relative of jellies that also has nematocyst cells) feel like sandpaper to the touch. Their nematocysts are firing, but the barbs aren’t powerful enough to puncture your skin.

With their probing paws and destructive behavior, the raccoon has gained a reputation as a garbage bandit, capable of finding a meal in any urban landscape. Yet despite their proximity to our homes and their evident resourcefulness, very few researchers have truly tested the problem-solving abilities of the “trash panda.” As part of a multi-year study exploring the cognition of raccoons, researchers at the University of Wyoming’s Animal Cognition Lab are pushing the limits of the species’ learning by providing both captivity and street-dwelling specimens with a variety of tests.

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

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.
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.

While known for being the world’s fastest bird–peregrines have been clocked at diving more than 200 miles per hour–these majestic birds were at risk for going extinct 50 years ago. Widespread use of pesticides such as DDT decimated native populations of peregrine falcons.
By 1970, California’s peregrine population had dwindled to only two known nesting pairs statewide. The federal government banned DDT in 1972. And successful restoration efforts spearheaded by organizations like The Peregrine Fund helped revive their numbers. By 1999, they were removed from the federal Endangered Species List. Recent surveys estimate that there are now 300 to 350 nesting pairs in California and more than 2400 pairs nationwide.

--- What’s the origin of the Peregrine Falcon's name?
Peregrine is Latin for "Peregrinus," which means “traveler” or “pilgrim.”
--- How many eyelids do raptors, or birds or prey, like peregrine falcons have?
They have three! Two eyelids are used for closing their eyes, while the third is used for blinking. It’s also called the nictitating membrane and helps to protect their eyes and keep them moist and clean. It’s semi-transparent, so they can actually still see through it when it’s closed.
--- Did you know they have a special bone to protect their eyes?
It’s called a sclerotic ring and helps support and secure their eyeballs within their skulls.

Alfalfa leafcutting bees are way better at pollinating alfalfa flowers than honeybees. They don’t mind getting thwacked in the face by the spring-loaded blooms. And that's good, because hungry cows depend on their hard work to make milk.

Sure, cows are important. But next time you eat ice cream, thank a bee.
Every summer, alfalfa leafcutting bees pollinate alfalfa in an intricate process that gets them thwacked by the flowers when they release the pollen that allows the plants to make seeds. The bees’ hard work came to fruition last week when growers in California finished harvesting the alfalfa seeds that will be grown to make nutritious hay for dairy cows.
This is how it works.
To produce alfalfa seeds, farmers let their plants grow until they bloom. They need help pollinating the tiny purple flowers, so that the female and male parts of the flower can come together and produce fertile seeds. That’s where the grayish, easygoing alfalfa leafcutting bees come in. Seed growers in California release the bees – known simply as cutters – in June and they work hard for a month.
Alfalfa’s flowers keep their reproductive organs hidden away inside a boat-shaped bottom petal called the keel petal, which is held closed by a thin membrane that creates a spring mechanism.
Cutter bees come up to the flower looking for nectar and pollen to feed on. When they land on the flower, the membrane holding the keel petal breaks and the long reproductive structure pops right up and smacks the upper petal or the bee, releasing its yellow pollen. This process is called “tripping the flower.”
When the flower is tripped, pollen falls on its female reproductive organ and fertilizes it; bees also carry pollen away on their hairy bodies and help fertilize other flowers. In a few weeks, each flower turns into a curly pod with seven to 10 seeds growing inside.
Cutters trip 80 percent of flowers they visit, compared to honeybees, which only trip about 10 percent.
---
--- What kind of a plant is alfalfa?
Alfalfa is a legume, like beans and chickpeas. Other legumes also hold their reproductive organs within a keel petal.
--- What do bees use leaves for?
Alfalfa leafcutting bees and other leafcutter bees cut leaf and petal pieces to build their nest inside a hole, such as a nook and cranny in a log. Alfalfa farmers provide bees with holes in styrofoam boards.

Salmon make a perilous voyage upstream past hungry eagles and bears to mate in forest creeks. When the salmon die, a new journey begins – with maggots.

For salmon lovers in California, October is “the peak of the return” when hundreds of thousands of Chinook salmon leave the open ocean and swim back to their ancestral streams to spawn and die. All along the Pacific coast, starting in the early summer and stretching as late as December, salmon wait offshore for the right timing to complete their journey inland.
In Alaska, the season starts in late June, when salmon head to streams in lush coastal forests. Although this annual migration is welcomed by fishermen who catch the salmon offshore, scientists are finding a much broader and holistic function of the spawning salmon: feeding the forest.
Millions of salmon make this migratory journey -- called running -- every year, and their silvery bodies all but obscure the rivers they pass through. This throng of salmon flesh coming into Alaska’s forests is a mass movement of nutrients from the salt waters of the ocean to the forest floor. Decomposing salmon on the sides of streams not only fertilize the soil beneath them, they also provide the base of a complex food web that depends upon them.
--- Why Do Salmon Swim Upstream?
Salmon run up freshwater streams and rivers to mate. A female salmon will dig a depression in the gravel with her tails and then deposit her eggs in the hole. Male salmon swim alongside the female and release a cloud of sperm at the same. The eggs are fertilized in the running water as the female buries them under a layer of gravel.
When the eggs hatch, they spend the first part of their lives hunting and growing in their home stream before heading out to sea to spend their adulthood.
--- Why Do Salmon Die After Mating?
Salmon typically mate once and then die, though some may return to the sea and come back to mate the subsequent year. Salmon put all of their energy into mating instead of maintaining the salmon’s body for the future. This is a type of mating strategy where adults die after a single mating episode is called semelparity.
