Introduction to Assassin Spider
The Assassin Spider is a lesson in specialized strategy. It does not win by being general; it wins by being perfectly shaped for one difficult task.

Why Assassin Spider are interesting
- Assassin spiders were first known from fossils in Baltic amber; living ones were found later, in Madagascar in the 1880s.
- The neck is a lengthened part of the hard front body, not a joint, and the jaws hinge near its top.
- The species was described in 1956 by the arachnologist Ray Forster, at first under the genus Archaea.
- Many Australian assassin spiders are confined to a single mountain range or patch of wet forest.
- Members of the family are also called pelican spiders, from the outline of the neck and jaws.
