The Myriapods, the
World’s Leggiest Animals
Rowland M. Shelley, Ph. D.; North Carolina
State Museum of Natural Sciences
Introduction
The myriapods comprise four classes of
multi-legged arthropods with at least 18 legs (9 pairs) in adults. Two of the
classes, the
Diplopoda (millipedes) and
Chilopoda
(centipedes), include primarily relatively large-bodied, macroscopic organisms
that are readily seen by the general public and are addressed in this website.
The other two classes, Symphyla and Pauropoda, lack common names and are
microscopic organisms that are at most only a few mm in length; they are not
covered here. The Diplopoda and Chilopoda are ecologically important classes
that occur throughout the temperate and tropical zones of the world and have
been unintentionally introduced by man onto most oceanic islands. They are major
components of terrestrial ecosystems including even xeric (desert) environments,
yet they are poorly known and have been relatively ignored by past and present
biologists.
Despite this inattention
by professional biologists, myriapods attract considerable interest from the
general public on all continents. Amateur chat lines exist on the Web;
large-bodied millipedes & centipedes are imported from tropical regions of Asia,
Africa, and South America and sold in pet stores throughout the US; and a
substantial number of people engage in husbandry. If one searches for millipedes
or centipedes on a search engine, a host of websites turn up, but much of the
information on them is inaccurate or incomplete. A need exists for a
professionally run website with factually accurate information that is
retrievable by search engines, and this site is designed to fill this
void.
These pages provide general information on both millipedes & centipedes and
sections on past, present, and projected research projects. The latter involve
extensive collaborations with colleagues both in the US and other countries and
continents, and will be updated periodically as new information becomes
available. There is also a table of differences between millipedes & centipedes
(it's more than just the number of legs) with photos and accurate information on these organisms. The general information
concludes with family-level taxonomies, and photos of representatives of North
American taxa will be accessible by clicking on names in these classifications.
