Brazilian wandering spider

The Brazilian Wandering Spider (Phoneutria fera) is an aggressive and highly venomous spider. It was first discovered in Brazil hence its name. However, this genus is known to exist elsewhere in South and Central America. The Brazilian Wandering spider is a member of the Ctenidae family of wandering spiders. The Brazilian Wandering spider appeared in the Guinness Book of World Records 2007 for being the most venomous animal. In this particular genus, there are five known similar species whose members are also highly venomous. They include some of the relatively few species of spiders that present a threat to human beings. Brazilian Wandering Spider Description The Brazilian wandering spider can grow to have a leg span of up to 4 – 5 inches. They are large hairy spindly-looking spiders who have eight eyes, two of which are large. Brazilian wandering spiders are fast-moving spiders, their legs are strong and spiny and they have distinctive red jaws which they display when angered. The Brazilian wandering spider is not a Tarantula. Brazilian wandering spiders are not even in the same family group. Tarantulas are harmless to humans and are mostly ambush killers who wait for prey to come to them. Brazilian wandering spiders are active hunters. Brazilian wandering spiders and Tarantulas do have one thing in common, however, they do not eat bananas. Brazilian Wandering Spider Habitat and Webs The Brazilian Wandering spider is so-called because it wanders the jungle floor, rather than residing in a lair or maintaining a web. This is another reason it is considered so dangerous. In densely populated areas, the Brazilian Wandering spider will usually search for cover and dark places to hide during daytime, leading it to hide within houses, clothes, cars, boots, boxes and log piles. This usually causes accidents when people disturb them. The Brazilian Wandering spider is also called the ‘banana spider’ as it is occasionally found within shipments of bananas. As a result, any large spider appearing in a bunch of bananas should be treated with due care. Brazilian Wandering Spider Diet Adult Brazilian Wandering spiders eat crickets, other large insects, small lizards and mice. Spiderlings of this species eat flightless fruit flies and pinhead crickets. Brazilian Wandering Spider Reproduction All spiders produce silk, a thin, strong protein strand extruded by the spider from spinnerets most commonly found on the end of the abdomen. Many species use it to trap insects in webs, although there are many species that hunt freely such as the Brazilian Wandering spider. Silk can be used to aid in climbing, form smooth walls for burrows, build egg sacs, wrap prey and temporarily hold sperm, among other applications. Brazilian Wandering spiders reproduce by means of eggs, which are packed into silk bundles called egg sacs. The male spider must (in most cases) make a timely departure after mating to escape before the females normal predatory instincts return. Mature male spiders have swollen bulbs on the end of their palps for this purpose and this is a useful way to identify the sex of a spider. Once the sperm is inside the female spider, she stores it in a chamber and only uses it during the egg-laying process, when the eggs come into contact with the male sperm for the first time and are fertilized. The Brazilian Wandering spiders life cycle is 1 – 2 years. Brazilian Wandering Spider Venom Bites from the Brazilian Wandering spider may result in only a couple of painful pinpricks to full-blown envenomed. In either case, people bitten by this spider or any Ctenid should seek immediate emergency treatment as the venom is possibly life threatening. The Phoneutria fera and Phoneutria nigriventer (two species of wandering spider) are the two most commonly implicated as the most vicious and deadly of the Phoneutria spiders. The Phoneutria not only has a potent neurotoxin, but is reported to have one of the most excruciatingly painful envenoms of all spiders due to its high concentration of serotonin. They have the most active venom of any living spiders. One of their members, the Brazilian Huntsman, is thought to be the most venomous spider in the world. Brazilian wandering spiders are certainly dangerous and bite more people than any other spiders.

Death Stalker Scorpion

Scorpions hunt, sting and kill their prey, and have been doing it for over 400 million years … since long before the age of the dinosaurs. Scorpions look like little lobsters, but they carry their curved tail above their head, and it’s a formidable weapon … it carries a stinger which they use to paralyze their prey. Some scorpions, like the Death Stalker pictured at the left, can kill humans.

There are more than 1500 species of scorpion; all are arthropods in the class ‘arachnida’, and so are closely related to spiders, mites and ticks. All scorpions are venomous, although most are not dangerously so. Most scorpions have a life span of two to six years.

Scorpions hunt at night; their prey includes insects, spiders, and other scorpions. Larger species also prey on small lizards, snakes and mice.

When a scorpion spots a victim, it will grab it with its claws, using its venomous tail stinger only if the prey is large or resists being eaten. If a human is stung by a scorpion, the usual symptoms are swelling, numbness and convulsions, as well as difficulty in breathing. Scorpion stings are rarely fatal to adults if medical attention is received. Children and older people are much more at risk of death, however.

The Death Stalker Scorpion
Lieurus quinquestriatus

Although it’s only a medium-sized scorpion, the Death Stalker is one of the most deadly scorpions on Earth. Its very potent venom helps it compensate for its smaller size and narrow, weak pincers; this scorpion’s sting injects extremely toxic venom (a neurotoxin) that can cause extreme pain, fever, convulsions, paralysis, and often coma or death in humans (by heart or respiratory failure). The Death Stalker Scorpion is found in North Africa and the Middle East. It prefers a dry climate, and makes its home in natural burrows or under stones.

The neurotoxins found in Death Stalker venom are being studied by scientists, who hope to find in them a treatment for some diseases, noteably some forms of brain cancer, and diabetes.
