Banana Spiders


The Brazilian wandering spiders, armed spiders, as they are known in Brazilian Portuguese, or banana spiders appear in Guinness World Records from 2010 as the world's most venomous spider. Guinness World Records states that although the Brazilian wandering spider venom is the most toxic, an effective antivenom is available and few fatalities occur. The spiders in the genus can grow to have a leg span of 13 to 15 cm (5.1 to 5.9 in). Their body length ranges from 17 to 48 mm (0.67 to 1.89 in). Despite their reputation as the world's deadliest spiders, there are multiple studies that call into question their capacity for fatal human envenomation, though some of these are labeled with a level of uncertainty, as Phoneutria are often confused with other genera of ctenids, lycosids or other large labidognatha spiders. Of the eight described species, P. nigriventer and P. fera most frequently receive mention in mass-media publications. P. nigriventer is the species responsible for most cases of venom intoxication in Brazil because it is commonly found in highly populated areas of southeastern Brazil, such as the states of São Paulo, Minas Gerais, Rio de Janeiro and Espírito Santo. The species P. fera is native to the northern portion of South America in the Amazon of Brazil, Venezuela, Ecuador, Peru and the Guyanas.

Fastest bird swift

we have seen them flying at about 9000 feet. If they need to they can fly twice that high. It is reported to reach a top speed of 169km/hour. The needle-tailed swift or spine-tailed swift is commonly reported as the fastest bird in level flight. There's still an awful lot that we don't know about them, making them a real Mystery Bird. They feed, drink, mate and sleep on the wing, and only land to breed. So a young Swift will spend its first two or three years in constant flight before it nests. Because they never land on the ground, and are so fast and so totally aerial. Swifts are amazing, beautiful birds. Supreme aerialists, they spend almost all their life in the air, a lot of that at low level, feeding on airborne insects.

sweden Mine hotel

It is deepest hotel in the world. The Sala Silvermine hotel locted at Scandinavia, in Sweden, in the county of Vastmanland and in the town of Sala. Hitting rock bottom on vacation can be a very cool experience. For it is there that travelers can find the Sala Silvermine and can stay in the accommodations of its Mine Suite. At 155 meters (509 feet) below ground level. As early as the 1400s and as late as 1962, miners excavated silver, lead and zinc from beneath the ground here. The town of Sala was ordered built on its current site by King Gustavus Adolphus in 1624 and all the infrastructure around it. Today, precious metals are no longer being extracted from the mine; it is operating purely as a tourist attraction.
