Figure 10. Grades 27 and 28. There are many different mygalomorphs today, characterized by the parallel, parasagittal (orthognath) alignment of their chelicerae. The Theraphosidae is the largest family in the group, including the largest of all spiders. In some countries, these are popularly known as tarantulas, and kept as low-maintenance pets. Filistatids like this Filistata are near the base of araneomorph evolution. Their anterior medial spinnerets have fused to form a cribellum with many small ducts. This produces a kind of kinky silk that entangles prey in the webs of these spiders.
