Tarantula. The body length of the largest tarantulas is about six centimeters, excluding the paw span. But with a relatively modest body size, the tarantula's paw span can reach 20-25 centimeters. All tarantulas are poisonous, but their venom is not capable of killing a person. In terms of toxicity and consequences, a tarantula bite for humans is comparable to a bee sting.
