Vintage cased entomology Goliath Bird Eating Spider from Peru. This spider is a member of the tarantula family (Theraphosidae) and is native to the northern areas of South America. The species is the world's largest spider (by body size and mass), and only second to the Giant Huntsman Spider in leg span. Nicely cased and ready to display. One of a small collection of entomology creatures that we have recently acquired (see other listings).
