Full Answer

Another Goliath bird-eating spider, reared as a pet in Great Britain, also had an 11-inch leg span and weighed 6 ounces, as of 1998. An even heavier spider weighed 6.1 ounces.

Despite its name, this spider does not mainly eat birds. Its usual diet is insects, but it also eats frogs, small mammals and reptiles.
