An Australian reptile park is seeking the identity of an anonymous donor who mailed in the “BIGGEST” spider of its kind, with fangs powerful enough to “bite through a human fingernail.”

The funnel web spider has been named “Megaspider,” according to a press statement from the Australian Reptile Park. While normal funnel spiders are between 1 and 5 centimeters, the Megaspider, which is described as being the biggest known spider of its kind, measures in at about 8 centimeters and has fangs approximately 2 centimeters lengthwise.
