Giant Spiders to Freak You Out: Photos

You almost feel for them, spiders. They can't help being what they are, and yet almost no one is happy to see them. Especially true when they have exceedingly long legs, thick bodies and a general mien that makes you turn quickly in some other direction.

Photos don't bite, though, so let's take a look at some honking-big spiders to start freaking ourselves out.

1. Brazilian wandering spider

Shown above is the Brazilian wandering spider (a.k.a. Phoneutria), a feisty and venomous crawler from South America. Just four years ago it took home an award from the Guinness World Record people for the title of "most venomous" spider.

This spidey's legs can span nearly 6 inches, its body just shy of 2 inches. It gets its name thanks to its preference for strolling along the tropic floor at night seeking out prey, rather than building webs or hiding out someplace waiting to strike. During the day, it lays low wherever it's convenient - even inside banana plants, which is how it get its nickname "banana spider."


2. Goliath bird-eater

Not to be outdone is a spider that's been making a big splash of late, with an entomologist's blog about his encounter with one. It's called the Goliath bird-eater (a.k.a., Theraphosa blondi), the world’s largest spider according to the Guinness World Record. It can weigh in at almost 6 ounces and it's been known to reach nearly a foot in leg-span.

The "bird eater" moniker must be there to warn birds away, though, because this spider doesn't typically eat birds as a matter of, er, course. It will regularly eat small land animals such as frogs, lizards, and snakes, however.


3. Golden-silk orb weaver spider

Meet the golden-silk orb weaver spider. Step into its parlour, if you must.

Don't be fooled by its deceptively gentle-sounding name. The female golden-silk orb weaver's body alone can reach 2 inches, its legs can stretch to more than 5 inches, and it's even been observed killing and eating tree snakes. What's more, a study published earlier this year found that these spiders, when living in urban areas, are growing even bigger than usual.

Interesting side-note: The golden-silk orb weaver also belongs to the oldest surviving genus of spiders, Nephila, which has a fossil in the record that dates to 165 million years ago.


4. Brazilian salmon pink bird-eating tarantula

The Brazilian salmon pink bird-eating tarantula has a leg-span that can reach 11 inches and weight that can tip the scales (well, for a spider) at about 3.5 ounces.

Despite its name, it's not confirmed that they actually eat birds any more than do the Goliath bird-eaters. Instead, they dine on insects or the random small amphibian or reptile. Instead of making a web, it takes its prey by quick-strike ambush in the open.


5. Giant huntsman spider

The giant huntsman spider is so big it even took the trouble to have a size descriptor built into its name (given that Goliath was taken). The huntsman is neck and neck, or leg and leg, with the Goliath bird-eater for the title of biggest spider, by leg-span (in sheer body mass, though, the Goliath is more like an offensive lineman, while this spider is a lanky cornerback). A giant huntsman's legs can stretch out to 12 inches, and its speedy, crab-like gait makes it a fast hunter that excels at chasing down its meals. It hails from caves in Laos.
