Understanding the Bird Eating Goliath Tarantula
When people hear “bird eating,” it often conjures images of spiders hunting birds, which sounds almost mythical given the typical prey size of spiders. The bird eating goliath tarantula earned its name not because it regularly preys on birds, but because it is capable of doing so. Its immense size and strength allow it to subdue small vertebrates including birds, frogs, and rodents, but its diet primarily consists of insects and other invertebrates.
Size and Appearance
The bird eating goliath tarantula is truly a giant among spiders. It can have a leg span of up to 12 inches (30 cm), making it roughly the size of a dinner plate. Its massive body can weigh over 6 ounces (170 grams), heavier than most small birds. The tarantula’s body is covered in dense, brownish hairs that provide camouflage in the forest floor’s leaf litter. These hairs also serve a defensive purpose; the spider can flick urticating hairs into the air to irritate potential predators.
Habitat and Distribution
This tarantula thrives in the humid, tropical rainforests of South America, where dense foliage and moist soil create an ideal environment. It typically resides in burrows on the forest floor, which it either digs itself or occupies after other animals have abandoned them. The burrow provides shelter from predators and harsh weather, as well as a strategic vantage point for hunting prey.
