THE BARKING SPIDER By Ethan Haigh

STRUCTURAL FEATURES/ADAPTATIONS AND BEHAVIOURAL FEATURES/ADAPTATIONS Some structural features/adaptations of the barking spider is it’s spinneret for sometimes making webs. Also it’s palps which are used for brushing dirt to get somewhere to live in. Their claw tufts are used to slowly dig though rocks. Some of the barking spiders behavioural features/adaptations are it’s bark which is used to scare it’s predators away. Another behavioural feature/adaptation is the film of oil that they grow so it is able to climb mountains. The next one is it’s suction caps that are above the oil it is connected to it’s lungs but a whole new muscle. It’s final behavioural feature/adaptation is it’s special lungs which are designed that the barking spider can breath in cold and hot and humid environments. The lungs have been designed that when the spider breathes it breathes in humid oxygen.

ADAPTATIONS • Some of the barking spiders adaptations is it’s ability to create a bark by rubbing it’s rows of spines on their Palaps against the spines on their lower jaw. Another adaptation of the barking spider is it’s gill-like lungs which require humidity. They have adapted to digging and spend most of their life in the moist underground. The deserts usually have flash floods and the barking spider lives in leaky roof burrows, the hairs on their bodies trap air bubbles which stop the spider from drowning. The barking spider also has brush feet with claw tufts and a film of oil which is produced from a special gland which gives them a suction cup ability to climb smooth vertical surfaces.

PREDATORS • The barking spider has 4 different predators they are red fox's, dingos, feral cats and owls. These 4 species have be growing in population super fast and also killing many barking spiders. This is the barking spiders real 1 threat on it’s survival. The barking spider uses it’s bark to evade/escape from it’s predators.

ENVIRONMENT • The barking spider are ground dwellers. Adult females live in a wed-lined burrows while younger spiders and males use flimsy silk retreats under rocks and logs. They live in mulga country deserts and in tropical rainforests of Queensland also in Alice spings desert.

Where the barking Spider lives.

GLOSSARY Flash floods- flash floods is a sudden flood, typically due to heavy rain. Film- A thin flexible strip of plastic or other material coated with light-sensitive emulsion. Spinneret- any of a number of different organs through which the silk, gossamer, or thread of spiders, silkworms, and certain other insects is produced. Theraphosidae- A family of very large chiefly tropical spiders with four spinnerets and the eight eyes in a compact group

FUN FACTS • Did you know the barking spider is know as Australia's tarantulas, as they belong the family Theraphosidae. The barking spider also has no teeth so they rely on their venom to kill their prey. They are also know as bird eating spiders as they have sometimes eaten small birds from nests that are on the ground. They also use their sucking stomachs to suck up their prey.
