Goliath Birdeater

The Goliath Birdeater is one of the world's largest tarantulas, with a leg span reaching 25 to 30 cm. Its stocky body and thick legs give it a presence unlike almost any other pet. Despite its intimidating size, it tends to move at a deliberate pace, and feeding is simple — insects and mice. With a lifespan of 15 to 25 years, it's a long-term companion for keepers ready for the commitment. As a large venomous species, it calls for solid prior experience and is best suited to advanced keepers.

About Goliath Birdeater

Meet the Goliath Birdeater, one of the world's largest tarantulas — leg span 25 to 30 cm, lifespan 15 to 25 years. A guide for advanced keepers considering this striking species.

7 things to know before welcoming a Goliath Birdeater

  1. 1Best Suited to Advanced Keepers

    The Goliath Birdeater is considered a difficult species to keep and isn't recommended as a first tarantula. Prior knowledge of large venomous spiders and the composure to handle them calmly are important before bringing one home.

  2. 2An Imposing Adult Size

    As an adult, this species reaches a leg span of 25 to 30 cm. Choose an enclosure with generous floor space and height from the start, planning ahead for its full-grown size.

  3. 3A Long-Term Commitment

    With a lifespan of 15 to 25 years, this is a long-term commitment worth thinking through carefully before adoption. Females in particular tend toward the longer end of that range.

  4. 4A Large Venomous Species

    As a venomous tarantula, care should be handled calmly with tools rather than bare hands. If a bite occurs or you notice anything unusual, consult a specialist promptly.

  5. 5Simple Feeding Habits

    Its diet consists of insects and mice. It's normal to see cycles of strong appetite followed by periods of little to no eating, especially around molting.

  6. 6Molting Is a Critical Time

    As it grows, it molts periodically, and this is a especially delicate time. When signs of an upcoming molt appear, avoid disturbing it and keep the environment quiet.

  7. 7Prepare the Enclosure Before Arrival

    Before bringing one home, set up an enclosure, substrate, hide, and temperature/humidity controls sized for its eventual adult size. Having everything ready in advance reduces stress on the animal.
