Spiders of family Liphistiidae are burrowing spiders characterized by the trapdoor-like structures on their burrows. The only family in this group is Liphistiidae, members of which are found in Southeast Asia. Due to this characteristic, spiders in this group are also known as segmented spiders. The spiders in Mesothelae have a segmented abdomen, which is a characteristic not seen in spiders that evolved later. The very first spiders, which are thought to have appeared in the Carboniferous period, tens of millions of years before the dinosaurs, may have resembled living Mesothelae spiders. Spiders belonging to each of these groups are listed further down the page. Opisthothelae is split into two infraorders, Mygalomorphae and Araneomorphae.
Mesothelae is the most primitive group of spiders, and it contains only a relatively small number of species (around 170 of the around 50,000 known spider species). The order Araneae, which contains all spiders, is divided into two suborders: Mesothelae and Opisthothelae.
The spiders on this page are separated into the three main spider groups, Mesothelae, Araneomorphae and Mygalomorphae. orb-weavers, tarantulas, huntsmen spiders, funnel-web spiders, etc., together with at least one example species from each group. On this page are listed many of the main types of spiders, e.g. The European garden spider Araneus diadematus is an orb-weaver. The three main types of spiders are: the suborder Mesothelae, which contains a relatively small number of primitive spiders, all of which are found in Southeast Asia the infraorder Mygalomorphae, which contains tarantulas and other spiders with downwards-facing fangs and the infraorder Araneomorphae, the largest group, which contains orb-weavers, jumping spiders, recluse spiders and many others. Scroll down to see other tarantulas, and many other types of spiders. Types Of Spiders The Mexican redknee tarantula belongs to the infraorder Mygalomorphae.
