Worlds Most Massive Spider – Goliath Bird Eating Spider

The Biggest Spider in the World by mass is the Goliath Bird eating spider which can be found in the rain forest regions of Northern South America. Considered to be the second largest spider in the world, but may be the largest by mass.

Its name derives from Victorian era explorers who witnessed a spider eating a hummingbird.

Goliath Birdeaters mature in 3 to 4 years and have an average life span of 15 to 25 years as opposed to their male counterparts who only live three to six years.

The spiders lack tibial spurs, usually located on adult male spiders.

These spurs serve to keep the fangs of the female immobilized during mating, so the female cannot eat the male which the female birdeater is known to do.

With a leg span of up to 12 inches, these spiders can weigh over 6oz.

The spider does have fangs large enough to break the skin, but the venom is relatively harmless, comparable to a wasp’s sting.

Contrary to its name, the Goliath Bird-eating spider does not normally eat birds.

Its diet consists mainly of insects and other invertebrates, but has been seen feeding on rodents, frogs and lizards.

Although huge, hairy and filled with attitude. Their populations are jeopardized due to habitat destruction of the rainforests.
