Kiwa are a genus of marine decapods that inhabit hydrothermal vents and cold seeps at deep-sea levels. They have three nicknames that are often used instead of their actual name – yeti crab, yeti lobster, or furry lobster.
The yeti crab farms its own food – on its arms
The hairy ‘arms’ of this tiny crab capture all kinds of bacteria that live and grow on the crab. To encourage growth, yeti crabs have been seen waving it’s arms back and forth in seeping vents.
As a result, the bacteria are the primary source of food for the yeti crab.
The yeti crab official name comes from mythology. The Polynesian goddess of shellfish was named Kiwa. -

A species endemic to North America, the asp caterpillar—Megalopyge opercularis—looks quite harmless. However, it should be treated with extreme caution as it has very powerful venom and is one of the most toxic caterpillars in North America. At the end of the fluffy hairs lie sharp, poisonous spines which pierce the skin and can cause extreme allergic reactions such as inflammation, blisters, headaches, nausea and breathing difficulties. These symptoms can last for days.
Many cases of injury have been reported in the United States over the years—the injuries occur mainly in children as they try to pick up these creatures. The asp caterpillar grows to two centimeters in length an the adult is the crinkled flannel moth, which also has a bizarre, yeti-like appearance. -

Relative to other insects, dragonflies have extraordinarily keen vision that helps them detect the movement of other flying critters and avoid in-flight collisions. Thanks to two huge compound eyes, the dragonfly has nearly 360° vision and can see a wider spectrum of colors than humans. Each compound eye contains 28,000 lenses or ommatidia and a dragonfly uses about 80% of its brain to process all of the visual information it receives.
Dragonflies are able to move each of their four wings independently. They can flap each wing up and down, and rotate their wings forward and back on an axis. Dragonflies can move straight up or down, fly backward, stop and hover, and make hairpin turns—at full speed or in slow motion. A dragonfly can fly forward at a speed of 100 body lengths per second (up to 30 miles per hour). -

The traditional appearance of the sea spider is that of long legs and a small body. Across the many species of sea spider, the leg count varies from 4 – 6 pairs. Sea spiders operate without the respiratory system that we are used to. Instead, they use their legs to take in vital gasses, such as oxygen. They also utilize a proboscis, which enables them to digest soft-bodied invertebrates via a sucking mechanism. Some species of sea spiders are so tiny that the muscles on their exoskeleton are made of just a single cell. The legs of sea spiders also contain their guts and genitals, which makes them very unique. -

Jumping spider eyes are, in a word, incredible. The spiders, despite their tiny size, are better at seeing patterns than elephants are. Their pair of central eyes, known as the principle eyes, are almost like a pair of tiny binoculars: They have a large outer lens, then a smaller inner lens that magnifies the image from the outer lens and projects it onto the retina. The spiders are also unusual in that they have muscles attached directly to their retinas. That means they can move retinas up and down, side to side, focusing on different segments of the world without a hint of movement on the outside — a handy ability for a hunter. Meanwhile, the spiders' secondary pairs of eyes are less acute, but they provide crucial peripheral vision, Live Science previously reported.
Most species of jumping spider can see ultraviolet light and blues and greens. Some species, though, have evolved special tricks to expand their color vision. These tend to be the flashier species, such as the paradise jumping spiders (genus Habbernatus), which are often decorated in shades of red and orange. In some species, a random genetic mutation has introduced an extra copy of the gene that makes the proteins that allow for blue/green vision. This extra copy has then acquired mutations capable of detecting red and orange. Similar mutations allowed primates to develop color vision.
Jumping spiders can live up to their name. These spiders don't hunt by snaring prey in a web, but rather they stalk their quarry and then leap. Despite their tiny body size, jumping spiders can leap up to 6.3 inches (160 mm), according to a 2018 paper in the journal Scientific Reports. The spiders often spin a little silk and set a thread-like "anchor" before they leap, which may help stabilize their flight and protect them in case their landing is off. Jumping spiders most often jump to catch their prey, but sometimes leap to flee danger. They can also be quite clever: Researchers in the 2018 study actually trained a jumping spider (Phidippus regius) to leap from platform to platform. -

Everyone loves the mantis shrimp, so here you go.
Mantis shrimp are either "spearers" or "smashers" depending on their claws and prey-killing tactics. Spearers have spiny appendages with barbed tips, that are used to stab soft-bodied prey, such as different types of worms and fish. Smashers have more developed club-like appendages that are used to bludgeon and smash their prey to pieces.
Smashers can punch at same velocity as a gunshot from a .22 caliber rifle. Smasher mantis shrimp have two raptorial appendages (called ‘dactyl clubs’) on the front of its body that it uses to punch its prey. These fists are spring loaded, able to accelerate from their body at over 50 mph, delivering a force of over 1,500 newtons, enough to smash through crabs and clam shells.
They can crack and punch holes in aquarium glass. While they are highly desired, they require special stronger aquariums. When they encounter an obstacle they wish to move, they often try and punch their way out. They have also been known to attack their own reflection through the glass.
Eyes of mantis shrimp are located on the long stalks that can move independently. Each eye has ‘trinocular vision’, which means it can gauge depth and distance on its own by focusing on objects with three separate regions. They are thought to have the most complex eyes in the animal kingdom and have the most complex visual system ever discovered They can see a special spiraling type of light called circularly polarized light that’s not been documented in any other animal. They also have a structure in their eyes that’s similar to technology found in DVD players, only much more advanced.
While they have significantly more color photo-receptors, research suggests they are actually worse at differentiating color than humans. However, scientists believe this is because their eyes are operating at a different level, functioning more like a satellite. It’s believed Mantis shrimp can take all visual information into their brains immediately without having to process it, allowing them to react instantly to the environment. -

🚨 ARTHROPOD OF THE DAY 🚨
The coconut crab — sometimes called a robber crab — boasts powerful pincers, which are some of the most dangerous weapons in the animal kingdom. Experts say a pinch from this crab can rival a lion’s bite. So there’s no question that they can do some terrifying things with their claws.
But the good news for humans is that the crabs don’t usually use their claws on us. As the name suggests, the coconut crab’s main source of food is coconuts. And since most of these creatures live on islands in the Pacific and Indian Oceans, they usually have no trouble finding their favorite food.
As omnivorous creatures, coconut crabs are willing to eat both plants and animals. They’ve been known to kill birds, feast on kittens, and rip apart pig carcasses. Eerily, they’ve also been known to practice cannibalism — and they will rarely hesitate to eat other coconut crabs.
In short, almost nothing is off the menu for a robber crab. They’ll even eat their own exoskeletons. -

A brown recluse’s venom can destroy blood vessels, tissue, and nerves. As a result, the skin tissue can die, a phenomenon called skin necrosis.
In the mature brown recluse spider as well as some other species of recluse spiders, the dark violin marking is well defined, with the neck of the violin pointing toward the bulbous abdomen.
Brown recluses have six eyes instead of the usual eight. These eyes are arranged in a horizontal row of 3 pairs on the face.
Only a few other spiders have 3 pairs of eyes arranged this way, such as the Spitting Spiders (scytodids). Brown Recluse Spiders can be distinguished from scytodids as recluse spiders abdomens have no coloration pattern nor do their legs, which also lack spines. -

Saddleback caterpillars, Acharia stimulea, have a brown saddle-shaped spot on the middle of their green backs. They are called slug caterpillars because the abdominal legs lack tiny hooks that most other caterpillars have, and because the six jointed legs are so short. Saddleback caterpillars are one of the stinging caterpillars that bear urticating hairs on four prominent knobs at the front and rear as well as smaller knobs along the sides. These caterpillars are about 3/4 inch long when mature and spin tough silk cocoons in which they overwinter. Saddleback caterpillar moths are fuzzy and dark brown with some cinnamon spots and tiny white spots. These moths emerge from the cocoons the following spring and summer and lay 30 to 50 tiny, flat eggs that overlap like fish scales on the upper surface of leaves of various trees and shrubs. From the eggs hatch tiny, almost transparent caterpillars that already display yellow, spine-covered knobs around their bodies. Aside from tiny parasitic wasps that plague saddleback caterpillars, other mortality factors such as diseases and predators usually keep the numbers of these caterpillars low. -

Millipedes have hard, cord-like bodies made up of multiple segments; each segment has a pair of legs. Because of their many pairs of closely arranged legs, millipedes tend to move slowly, with their legs pushing in a wave-like pattern. When alarmed, millipedes coil up in a tight spiral shape. Size varies greatly by species, with the smallest millipedes measuring about 2 cm in length. While tropical millipedes may measure as long as 30 cm, most Canadian millipede species only reach a length of about 8 cm. Most millipedes are entirely black, though some species may appear dark brown or reddish. They have short but visible antennae made up of 7 segments.
Millipedes are ground-dwelling arthropods that live outdoors and thrive in dark habitats with plenty of moisture. Known to feed on decaying plant matter, millipedes often reside directly within sources of food, like piles of leaf litter or rotting logs. The arthropods also commonly burrow in areas where soil stays moist, like under rocks or piles of mulch. -

Although they look like really small scorpions, Pseudoscorpions lack a tail or stinger. They have venom glands in their claws meant to kill tiny mites and springtails. They are so small, however, they pose no threat to humans and would require a magnifying glass in order to get a really good look at them. Because they do not have wings, traveling long distances can be difficult. Their minute stature allows them to catch free rides on oblivious larger insects, like beetles and even flies. Some species are blind, but even those with sight are not able to see well. They use their claws like antennae, feeling and touching their surroundings to find their way around.
Pseudoscorpions can make their own silk, but they do not spin webs or use it to catch prey like a spider would. Instead, they build cocoons to shelter in during cold winters. Look for them in a variety of places: between book pages, at the water's edge, in caves, woods, under rocks, and maybe even in a house (bathroom, laundry room, etc.).©InsectIdentification.org -

An arthropod everyone hates - mosquitoes.
The slender, elongated body of the adult is covered with scales as are the veins of the wings. Mosquitoes are also characterized by long, fragile-looking legs and elongated, piercing mouthparts. The feathery antennae of the male are generally bushier than those of the female. The males, and sometimes the females, feed on nectar and other plant juices. In most species, however, the females require the proteins obtained from a blood meal in order to mature their eggs. Different species of mosquitoes show preferences and, in many cases, narrow restrictions as to host animals.
There are three important mosquito genera. Anopheles, the only known carrier of malaria, also transmits filariasis and encephalitis.
The genus Culex is a carrier of viral encephalitis and, in tropical and subtropical climates, of filariasis.
The genus Aedes carries the pathogens that cause yellow fever, dengue, Zika fever, and encephalitis. -
