Pet of the week: The Goliath Birdeater

(Alamy)

Who is this fearsome-looking beast? Theraphosa blondi, the largest mygalomorph there is, with a leg span equivalent to a small dinner plate (up to 12 inches). This is most definitely not an itsy-bitsy spider, climbing up the wall. In fact, he is so heavy that climbing up walls is probably not an option, being as he weighs more than your average mouse.

And does he really eat birds? No. The story goes that a Victorian explorer spotted one of these fellows on an Amazonian trip, watched it devouring a hummingbird and gave it its name. Generally, though, the Goliath sticks to crickets, insects and the occasional rodent.

Wouldn't want to find him in my sock drawer ... Most unlikely, as his natural habitat is the swamplands of northern South America. The natives consider these spiders a delicacy, but if they don't get eaten by humans, the males end up on the menu of their paramours.

Meaning? Meaning that once the male Goliath has done his family duty, he is usually killed or maimed by the female. New York divorce lawyers, take note.

Why would I want him as a pet? Well, they don't actually make good pets, as they are quite aggressive. But other species of tarantula are happy to be kept, and relatively easy to look after. Mature spiders (say, more than 3 years) will only need feeding on crickets (available from pet stores) once a week, and they don't need large terrariums. The Goliath is a burrower and would need an enclosed environment to mimic its habitat, but it's strictly for those with arachnid experience. Handling is proven to be more stressful for the spider than for the handler. Not that I'd ever have the guts to put that to the test.

Where can I find out more? If you are keen to own a tarantula, then there are many more friendly species, such as the Chile rose, the curly-haired and the Mexican red knee.
