FunTranscript
00:00They're watching you, hiding among leaves and stems, crevices and rocks, detecting way
00:05more colors than you do.
00:07These awesome creatures are jumping spiders, and scientists are mesmerized by their seemingly
00:12simple eyes that can do great things.
00:15This is the largest family of spiders, and they rely heavily on vision as their primary
00:20sense.
00:21That's why they have eyes that function like minuscule telescopes, allowing them to see
00:26with outstanding color and detail.
00:29Another amazing thing about their eyes is that they can move independently.
00:33This feature lets them estimate depth using just one eye.
00:37Among others, jumping spiders have six motion detection eyes, thanks to which they have
00:42an almost 360-degree view.
00:45This super ability helps spiders identify threats as well as prey in no time.
00:50Male jumping spiders are also excellent dancers, yeah!
00:54To attract the attention of females, they do a little dance involving beating their
00:58abdomens on the ground and moving their legs in the air.
01:02While doing it all, male spiders tap their feet against the ground so fast that the human
01:07eye can't detect it.
01:09Another surprising feature of these spiders that distinguishes them from other arachnids
01:13is that they don't use webs to trap their prey.
01:16The thing is, they just jump too well to even eat it.
01:20At the same time, it doesn't mean they can't produce silk.
01:23Female jumping spiders make tiny tents and shelters to hide from rain and nighttime predators.
01:28Plus, when a jumping spider, well, jumps, it anchors itself with a string, just in case
01:34it misses its target.
01:38Velvet worms might look harmless and gentle, but they're active and perilous carnivores.
01:44They prefer to feast on small invertebrates like termites, small spiders, and wood lice.
01:49But the coolest thing about these creatures is probably how they catch their prey – by
01:53throwing sticky slime from their oral tubes.
01:57Eww.
01:58This slime entangles the prey so effectively that it has no chance of escaping.
02:03Then the worm emits digested saliva that softens its future dinner.
02:07Afterward, it gradually bites off parts of its meal and pulls them into its mouth.
02:12If there are any undigested portions, they're removed through the rear of the worm's body.
02:18By the way, that yucky slime can also serve as a self-defense mechanism.
02:22Yeah, you just can't unsee this stuff, can you?
02:28Salamanders are truly remarkable creatures.
02:30If this amphibian loses a toe, it simply grows back.
02:34If something chops away a piece of its heart or even spinal cord, it will regenerate.
02:39One of the most well-known salamanders is the axolotl, which is found in lakes near
02:43Mexico City.
02:45This creature is a true Peter Pan of the salamander world.
02:48Even a 12-inch long reproductive adult has certain features of its youthful phase throughout
02:53its full life cycle.
02:55For example, these prominent gills protruding from the back of the animal's head are retained
03:00from its larval phase.
03:02Scientists are trying to unravel the mystery behind the incredible regenerative abilities
03:06of the salamander.
03:08They found out that its molecules somehow command cells inside the injured axolotl to
03:13develop and move, often restoring an entire limb in the right proportion and size.
03:19Such regeneration is possible as far as the shoulder, and it looks as if the animal is
03:23growing a limb for the first time.
03:28You probably know about lizards that shed their still-wriggling tails when threatened.
03:33They do it to distract predators.
03:35But sea cucumbers take the strategy to the next level.
03:38Even startled, some of these creatures shoot a sticky, silky substance out of their rear
03:43ends.
03:44And that substance is actually a whole organ.
03:47At first sight, this tangle of tubules looks like intestines.
03:51But it actually evolved from the creature's respiratory system.
03:55And just like a lizard's tail, it regenerates after the sea cucumber uses it.
04:00Researchers analyzed the entire genome of the sea cucumber to figure out the mechanism
04:04it uses to accomplish this outstanding feat.
04:07They believe that certain proteins might be responsible for expelling the organ.
04:12They also have concluded that the silk proteins of sea cucumber's tubules don't have the
04:16same sequence of amino acids as spider silk.
04:20On the other hand, they also are made up of long, repeated chains of amino acids.
04:25This discovery might mean that such long repeats are likely to be a shared structure in many
04:30silk-like proteins, even when they evolved independently.
04:36Can you imagine when I say shrimp?
04:38Right, a small and unassuming creature.
04:41But there's one tiny wonder out there called the pistol shrimp that is so powerful it can
04:46annihilate its prey.
04:48Pistol shrimps are also known as snapping shrimps.
04:51They're pros at creating something seemingly childish and harmless as bubbles.
04:56But those aren't your ordinary bubbles.
04:58They produce a sound louder than a gun and generate enormous amounts of heat.
05:02The pistol shrimp can not only send fatal bubbles to eliminate its prey, but they also
05:07jackhammer into the rock to make burrows and protect these burrows from other shrimps.
05:12To do this magic, the creature uses one oversized snapper claw that often grows to be half the
05:18size of its body.
05:22Moisture-harvesting lizards, like the Australian thorny devil, have one remarkable ability
05:27that helps them survive in super-arid regions.
05:30They have a special skin structure with tiny capillary channels in between their overlapping
05:35scales.
05:36This allows the lizard to collect water into these capillaries and transport it to the
05:40mouth for ingestion.
05:42The animal can get water from any available source – rainfall, dew, puddles, moist sand,
05:48and even condensation on the skin.
05:50The amount of water the creature needs to fill the skin capillaries is just a bit more
05:54than 3% of its body mass.
05:59Wood frogs have an uncanny ability to freeze up to 60% of their bodies to survive winter.
06:05But that's not all.
06:06Alaskan wood frogs also stop breathing, and their hearts stop beating.
06:11Thanks to this, wood frogs can live through temperatures as low as 3 degrees Fahrenheit.
06:17And in the spring, they simply thaw out.
06:20To enter this semi-frozen state, wood frogs build up a high concentration of glucose in
06:24their tissues and organs.
06:26This glucose level can be 100 times the norm.
06:30Sugar acts as a cryoprotectant – it prevents ice crystals from forming in the animal's
06:35cells.
06:36Otherwise, they could puncture blood vessels and damage tissues.
06:41Some species of Antarctic fish have special antifreeze proteins in their blood.
06:47Without them, they wouldn't be able to survive in the frigid waters of the southern oceans
06:50surrounding Antarctica.
06:53No fish can live at temperatures of around 28 degrees Fahrenheit.
06:57But these antifreeze proteins bind to ice crystals in the fish's blood, which stops
07:01the crystals from growing there and harming cells and tissues.
07:05Scientists believe that after interacting with the proteins, ice crystals might travel
07:10to the fish's spleen, where they remain stored until the fish get rid of them.
07:14It's still unclear how it happens.
07:17Maybe these crystals melt?
07:19Such an extraordinary adaptation explains why these fish make up around 90% of the fish
07:24biomass in that region.
07:28Tubeworms are amazing creatures.
07:30They can thrive in a mix of ultra-hot water heated by magma and oxygenated seawater.
07:35Once, scientists thought that the deep ocean floor was totally devoid of life.
07:40But in 1977, they discovered giant tubeworms living along the Galapagos Rift, around 1.5
07:47miles below the ocean's surface.
07:49These creatures literally thrived in hydrothermal vents.
07:53Tubeworms live there, surrounded by total darkness.
07:56Their bases remain in hot hydrothermal fluid, water filled with dissolved elements and compounds.
08:02Meanwhile, their tops stretch into oxygenated seawater.
08:07Tubeworms can reach lengths of over 6 feet, and they have no digestive system.
08:11Their long white tubes end in red plumes.
08:14Those are full of hemoglobin.
08:16The plumes act like gills, circulating oxygen, hydrogen sulfide, and carbon dioxide.
08:21Inside tubeworms, there are bacteria producing carbohydrates and proteins.
08:26These bacteria feed both themselves and the worms.
08:32Pufferfish can inflate to enormous sizes, more than double their original size.
08:37You see, the problem is that slow-swimming fish can't always escape predators due to
08:41their speed limitations.
08:43Pufferfish have elastic stomachs that can be inflated with water if they feel threatened.
08:49Interestingly, pufferfish's cousins have spines instead of scales that pop up when
08:54they puff.
08:55It makes them look especially threatening.
08:57Anyway, sometimes pufferfish expand just to stretch their muscles.
09:01In any case, they can swell up to more than twice their original size.
09:07That's it for today!
