Throughout the world, they are considered as a popular exotic pets, as most of the tarantulas are non-poisonous to humans. In Sri Lanka, the largest known specimens are size of a dinner plate, [1] or size of the palm.
While roughly 3,000 species of spiders are found throughout the U.S., very few pose a direct threat to humans. Spider bites are rare, and medically significant incidents are even less common ...
