Golia Bordi, Goliath bird-eating spider, is the world’s largest spider. The most heavily on record was the captive adult female named Rosie, who was at the top of 175 grams scales. It usually feeds on insects such as briars and beetles, but they eat small mammals, frogs and reptiles, poisoning them in its prey, with 20 mm fungs.

If that bite of these species is not obviously worse than the wasp sting. Young Theodora Blue spiders can take 2-3 years to mature and female mature can live for up to 20 years. They are often kept as pets. Like other titulos, theraophosas continue to proliferate in adult adults, which enables them to regenerate or regenerate any acquired or damaged organ. Species were first described by Pierre Andre Latterrell in 1804, a French arthropodologist.


Pet theraphosa blondi spiders require a tank or terrarium that’s at least three times larger than their leg span, and a lid that firmly locks in place. Depending on your spider’s size, you might need a habitat up to 30 gallons.

Supply the spider with at least 4 inches of substrate and preferably more so she can dig a burrow. Substrates such as bark, rain forest blend and vermiculate are usually available at pet stores. You also can provide your spider with a shelter, such as a log or a hollow aquarium rock, where she can hide aboveground. Finally, she needs a small, shallow water dish.


In the southwestern United States, species of the genus Aphonopelma can attain a body length up to 5 cm and a leg span up to 12.5 cm (almost 5 inches). The spiders, dark in colour and sluggish in movement, have a hairy body and hairy legs. The most common member of that genus is A. californicum, which is found in California, Texas, and Arizona. A 30-year life span has been recorded for one individual of that species.


Although called a ‘bird-eater’, Theraphosa blondi doesn’t normally eat birds.It usually feeds on insects such as crickets and beetles, but it will also eat small mammals, frogs and reptiles.Like most spiders, Theraphosa blondi has poor eyesight so it relies mainly on sensing ground vibrations.It will rush out of its silk-lined burrow when it detects potential prey, and subdues it by injecting it with venom though its 20mm long fangs.Although very formidable looking, a bite from this species is apparently no worse than a wasp sting.An adult female lays 50–150 eggs in a huge silk egg sac.

Diet /Feeding

Even though the Goliath Bird-Eater Spider got its name from eating a bird, they rarely are seen doing so. They typically will consume all types of insects. they are larger sized Spiders though so they will also eat rodents, snakes, bats, and lizards too. They will take the opportunity to eat whatever comes along.
