The terms poisonous and venomous are often interchanged. Letâ??s begin by distinguishing poison and venom.
A poison is something that is absorbed or ingested. Thus a poisonous animal can only deliver toxic chemicals if another animal touches or eats it. On the other hand, venom is always injected. Venomous animals have a mechanism to inject toxins to other animals via teeth, spines, spikes or harpoons.
According to Kyle Hill, a science writer, these are the most poisonous creatures on Earth:
The Golden Poison Frog is one of the most poisonous creatures on earth. They are also called as the Golden Dart Frog. This type of frog is an amphibian; it is carnivorous since it only eats meat. It has a life span of 10 years. Its size is only 1 inch (2.5 cm) or its size is relative to a paper clip. The golden poison frog has a congested skin that is coated with alkaloid poison which is one of the poisons that is common to dart frogs.
Sydney Funnel Web Spider is one of the most venomous creatures on earth. It is usually found in Sydney, New South WalesÂ AustraliaÂ within a 100Â km (62Â mi) radius. Sydney funnel-webs have sizes that range from medium to large, and its body length is 1 to 5 cm (0.39 to 2.0 in). The colors range from black-blue, to brown and dark-plum hues. The carapace that is covering the anterior partÂ ofÂ theÂ body is almost smooth and hairless, glossy and darkly colored in appearance.
Sydney Spiders live in moist sand and clays. They are mostly land or earth spiders, most of them can build a silk-lined hole or a tunnel that causes collapsing of the grounds. A Funnel-web spider contains venom which is known asÂ atracotoxin compound, anÂ ion channel inhibitor that blocks the charge particle to move the inhibitor, which produces highly toxic venom for humans and other animals like monkeys. Inspite of that, the venom does not affect the other mammalâ??s nervous system.Â When spiders bite they deliver the entire poisonous material in your body, many times striking again and again, due to their largeÂ fangs. A female funnel-web spider has no record of extreme poison which validates the fact that the female specimen has lesser venom than their male counterparts..
These are just two of the most poisonous creatures on earth. Run for your life whenever you see one of these.
