Mygalomorphae
The Mygalomorphae, or mygalomorphs, are an infraorder of spiders, and comprise one of three major groups of living spiders with over 3000 species, found on all continents except Antarctica. Many members are known as trapdoor spiders due to them forming trapdoors over their burrows. Other prominent groups include Australian funnel web spiders and tarantulas, with the latter accounting for around one third of all mygalomorphs. Description This group of spiders comprises mostly heavy-bodied, stout-legged spiders including tarantulas, Australian funnel-web spiders, mouse spiders, and various families of spiders commonly called trapdoor spiders. Like the " primitive" suborder of spiders Mesothelae, they have two pairs of book lungs, and downward-pointing chelicerae. Because of this, the two groups were once believed to be closely related. Later it was realized that the common ancestors of all spiders had these features (a state known as symplesiomorphy). Following the branching ...

Actinopodidae
Actinopodidae ( Mouse spiders) is a family of mygalomorph orb weaver spiders found in mainland Australia and South America usually in open forest. Species are most common in Queensland, Australia. It includes mouse spiders, whose bites, though rare, are considered medically significant and potentially dangerous. Description Actinopodidae has wider vision then most other Australian mygalomorphs and have a wide front to there carapace. Mouse spiders are stout black with species size varying from 10 mm-35 mm in length. Species have distinctively bulbous heads and jaw regions. Mouse spiders are oftentimes confused with funnel-web spiders. Depending on the species, the abdomen is black or dark blue with a light grey to white patch top. Legs are dark and may appear thin and the head is shiny black. Female of the family are stockier and larger. Burrow Mouse spiders live in soil covered burrows with a hinged top. Burrows can extent to a depth of 30 cm (12 inches). The ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Spiders Described In 1961
Spiders ( order Araneae) are air-breathing arthropods that have eight legs, chelicerae with fangs generally able to inject venom, and spinnerets that extrude silk. They are the largest order of arachnids and rank seventh in total species diversity among all orders of organisms. Spiders are found worldwide on every continent except for Antarctica, and have become established in nearly every land habitat. , 50,356 spider species in 132 families have been recorded by taxonomists. However, there has been debate among scientists about how families should be classified, with over 20 different classifications proposed since 1900. Anatomically, spiders (as with all arachnids) differ from other arthropods in that the usual body segments are fused into two tagmata, the cephalothorax or prosoma, and the opisthosoma, or abdomen, and joined by a small, cylindrical pedicel, however, as there is currently neither paleontological nor embryological evidence that spiders ever had a separate t ...
