What arachnologist worth his salt could forget the arachnid with a two-foot legspan?

Otherwise known as whipspiders, these creatures appear to have been formed in the deep recesses of a human nightmare, and yet are the only large arachnids that are entirely harmless to humans. Predatory whipspiders display advanced social behaviors and externally visible reproductive biology of immense complexity. This text presents cutting edge biological...

The pillbug and its relatives are beloved the world over by children-in this text they get their due for adults. Spectacular cultivars and amazing species represent an often forgotten group of backyard arthropods. In recent years the beautiful peach pillbug, zebra armadillo-bug, and Dalmatian isopod, among others, have burst on the scene in a growing hobby.
