Australia's fascinating spiders

Mygalomorph spiders have fangs that strike downwards. They also have 2 pairs of primitive lungs called book lungs. Their breathing system is not as efficient as Araneomorph spiders, and they are generally less active as a result. Most primitive spiders live in moist places such as burrows in the ground, and usually only venture out at night. This group also includes trapdoor spiders and tarantulas.

Araneomorph spiders are generally more active than their primitive cousins. They have one pair of book lungs and a more efficient breathing system; a spiracle. These spiders have fangs that oppose each other like pincers. They occupy a greater variety of habitats than Mygalomorphs – including our homes. This is a very diverse group of spiders and also includes huntsmen, orb-weavers, jumping spiders, water spiders, white-tailed spiders and the Redback.
