Mediterranean Black Widow
The black widow boasts a venom 15 times stronger than that of a rattlesnake. On the other hand, the Mediterranean black widow is more lethal than the common black widow and packs a venom that acts ten times faster than its famous cousin. This deadly arachnid is specifically toxic to humans, insects, and small mammals. Their tiny hour-glass frame often fools most people, but this spider is far from your friendly neighborhood spider.
