The Surprising Secrets of Australia's Cave Spiders

Facts about Australia’s Cave Spiders

Australia is known for its unique wildlife. Australian cave spiders are a perfect example. Australian cave spiders are not poisonous but aggressive and territorial, making them less appealing as pets. Australian cave spider populations can grow as large as 10,000 individuals per acre of land! This incredible density has led some scientists to study Australian cave spiders to better understand how humans might live on other planets with extreme climates such as Mars or the moon.

  • The Australian Cave Spider is an arachnid that lives in caves
  • They are most commonly found in the Northern Territory of Australia
  • These spiders have an extensive range, with colonies spanning from Western Australia to Queensland
  • One of their most attractive qualities is being able to live without oxygen for up to three weeks at a time by living off their fat reserves
  • Their diet consists primarily of insects and other small invertebrates they find on cave ceilings
  • They are also preyed upon by bats, birds, and lizards

Description of Cave Dwelling Spiders

The species has been identified as the Cave Dweller spider, an arachnid that typically lives in moist underground passages. It’s believed that recent construction works near these tunnels have disturbed both the spiders and their habitats, which has forced them to move into homes in search of food and water.

How Giant is a Tasmanian cave spider?

The question of just how big the Tasmanian cave spider is has been the subject of some controversy. Some say it’s as big as your hand, while others say it’s only the size of a nickel.  If you believe everything you read on the internet, you might think this spider is more significant than your face. 

There are several different troglobitic spiders in Tasmania, but their size varies depending on whether they live in the north or south of the island and how deep into the ground they are found. The Tasmanian cave spider that lives the furthest south is found up to 100m below the surface, while those in the north of Tasmania are located only about 25m underground.

People who claim to have seen these spiders say they can be anywhere from 10cm long up to 30cm. The Tasmanian Parks and Wildlife Service says that individual spiders might get bigger than this, but “spiderlings” (immature spiders) are much smaller. A newly hatched spiderling might only be 0.5mm across – 1000 of these would fit on a penny.

The size of a Tasmanian cave spider is debatable, but it’s tiny and harmless to humans. If you see one, admire it from a distance and don’t touch it or try to catch it.

Cave spiders are usually found in small groups, but more enormous cave spider nests have been discovered with over 100 cave spiders – which is extremely dangerous for experienced adventurers.

. However, cave spiders are dangerous because they are so small and hard to see in their natural environment – which is dark cave systems. This means that cave spiders often attack people when they least expect it!

Most cases have been reported to have involved cave spiders biting someone’s leg, with the poison working its way up into the heart.

These are often found in dark niches and hollows within buildings or other structures and inside logs. They like to make their homes in crevices or voids of African caves, where they get their name.
