Things that happen to spiders while on drugs
|
view preview
During this experiment, spiders were exposed to a variety of drugs to help determine their effect on the brain. Spiders who had been given marijuana started out well enough, but were unable to maintain focus. Benzedrine (speed) produced spiders who spun enthusiastically, though no great thought or care was put into the web design. Caffeine, one of the most common stimulants taken by humans, produced an erratic web. Chloral hydrate, an ingredient in sleeping pills, made the spiders doze off after barely getting started on the web. Though this 1995 experiment sought to determine toxicity of drugs, it was a continuation of experimentation of spiders on drugs that had started in 1948 by P. N. Witt. ...

Jumping spiders
|
view preview
Meet the green jumping spider ( Mopsus mormon), Australia’s largest—and perhaps cutest—jumping arachnid. These spiders hunt in the day time, moving fast to attack their prey, and camouflaging against green leaves. If you see one, leave it alone. Although their bite won’t kill you, it’s extremely painful.

Nature's gymnast lurking in the deserts of Morocco
|
view preview
Found in the deserts of Morocco, the cartwheeling spider ( cebrennus rechenbergi) uses all eight of its legs to cartwheel and roll away from predators. Using forward or backward flips, this movement effectively doubles its normal walking speed similar to acrobatic flic-flac movements used by gymnasts. Interestingly, C. rechenbergi is the only spider known to use this unique form of rolling locomotion!

Surfing spider discovered
|
view preview
The creature you see above is a spider that can actually surf on top of waves and hunt for a wide variety of animals including not only insects but also fish and toads. Dubbed the Dolomedes briangreenei, this species of spider floats on top of water and senses vibrations below to detect potential prey. The spider can even submerge itself underwater for up to an hour to hunt down prey, which makes it doubly frightening for any creatures caught in its path. The largest animals that the spider has been known to eat are cane toads, which can measure up to nine inches in length. For comparison, the D. briangreenei is about the size of a human palm. ...

Super strange spider found off Antarctica
|
view preview
Collected from the Ross Sea shelf in southern Antarctica, this 9.8-inch-long (25-centimeter-long) giant sea spider was one of 30,000 animals found during a 35-day census in early 2008. The marine arachnids, which prey on hydroids and bryzoans - branching, coral-like animals - are larger and more common in Antarctic waters than anywhere else on Earth. Cold temperatures, few predators, and high levels of oxygen in seawater could explain their gargantuan size.

As this tarantula matures, its abdomen changes from blue to red
|
view preview
As its scientific name suggests, the Antilles pinktoe tarantula ( Avicularia versicolor) changes color as it matures. The spider’s abdomen turns from blue to pink or red and the carapace becomes metallic green. Antilles pinktoe tarantulas are native to Guadeloupe, Dominica and Martinique in the Caribbean Sea. They are arboreal (tree-dwelling) species, and can spin elaborate funnel webs in which they spend most of their time. Though these tarantulas are naturally docile, they are quick and can jump up to 30 cm far or high! ...

Next time you experience acne, try not to remember this
|
view preview
Demodex folliculorum and Demodex brevisare are parasitic mites that particularly favour the hair follicles of eyebrows and eyelashes and measure a mere fraction of a millimeter long. They crawl about your face in the dark to mate and then crawl into the pores to lay their eggs and die. Healthy adults have around one or two mites per square centimetre of facial skin, though people with the condition rosacea can have 10 times more. Demodex does not have an anus and therefore cannot get rid of its faeces. Instead, their abdomen gets bigger and bigger, and when the mite dies it decomposes and releases its faeces all at once into the pore. ...
