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

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

poison dart frog pictures and information
Poison dart frogs, like this sapphire-blue species, are highly toxic. Their brilliant colors serve as warnings to potential predators to keep away continue

Poison dart frogs, members of the Dendrobatidae family, wear some of the most brilliant and beautiful colors on Earth. Depending on individual habitats, which extend from the tropical forests of Costa Rica to Brazil, their coloring can be yellow, gold, copper, red, green, blue, or black. Their elaborate designs and hues are deliberately ostentatious to ward off potential predators, a tactic called aposematic coloration.
Some species display unusual parenting habits, including carrying both eggs and tadpoles on their backs. Although this "backpacking" is not unique among amphibians, male poison arrow frogs are exceptional in their care, attending to the clutch, sometimes exclusively, and performing vital transportation duties

Dendrobatids include some of the most toxic animals on Earth. The two-inch-long (five-centimeter-long) golden poison dart frog has enough venom to kill 10 grown men. Indigenous Emberá people of Colombia have used its powerful venom for centuries to tip their blowgun darts when hunting, hence the genus' common name.
Scientists are unsure of the source of poison dart frogs' toxicity, but it is possible they assimilate plant poisons which are carried by their prey, including ants, termites and beetles. Poison dart frogs raised in captivity and isolated from insects in their native habitat never develop venom.
The medical research community has been exploring possible medicinal uses for some poison dart frog venom. They have already developed a synthetic version of one compound that shows promise as a painkiller
