Navigation Menu. McGrew-Hill Book Company ]. Chitons are classified in the Order Polyplacophora. More than species are grouped into approximately 10 Families, depending on which classification you subscribe to.

Most Chitons live in intertidal zones, but some species dwell in rather deep water. Chitons are distributed in all oceans from the polar regions through the tropics. The greatest concentration of species, though, is along the west coast of North America and in Australia, where at least 50 percent of the know species are found. Unlike many of the drab-colored, cold-water gastropods and bivalves, Chitons often exhibit beautiful colors and striking patterns in these cold regions.

An outstanding characteristic of Chitons is the variability of color and pattern that can be exhibited by one species. The polymorphic nature of many Chitons has made the group a growing favorite of collectors. Displaying a series of color forms can elicit a gasp of "wow" from even the most staid individuals. It is a rarity to find a Chiton with only 7 valves instead of the typical 8, and even more unusual is one with 9 valves.

Chitons that have aberrant numbers of valves are highly prized by collectors and command very high prices. Another rarity are Chiton hybrids.

I know of one Chiton population that hybridizes , and I suspect that others may eventually be found. Two important factors to be considered when preparing chitons for a collection. First, a Chiton must be properly collected, and secondly, undergo a special preservation process that will prevent it from curling up into a permanent pillbug-like ball.

When properly collected and preserved, Chitons will last a lifetime in a collection. Preserving Chitons Flat as a Board , is an article that will take you step-by-step through the process of Chiton preservation. It is available to read here on worldwideconchology. The article first appeared in Volume 26, No. Keeping the girdle intact for display is far more desirable than having a specimen with disarticulated valves. Chiton girdles are, in many cases, as fascinating as the often beautifully ornamented valves.

Some girdles have snakeskin-like scales , or are covered with shaggy hairs. Others have sharp spicules of varying length. Many though, are papers published in scientific journals such as an important series of revisions to various Chiton Families and Genera, as well as geographical treatments, authored by the late Antonio J.

Slieker pages, hardcover. L''Informatore Piceno, Ancona, Italy. ISBN - has brought together the large body of scientific literature on Chitons into one popular tome. More than species are covered and illustrated in color, with illustrations of 61 type specimens. The book arranges the species by faunal provinces, helping narrow down the identification of well-documented specimens.

This is an important publication recommended for anyone interested in collecting and identifying Chitons. The page book contains a wealth of information on all of the known Chiton species from this region. Catalogue of the Living Chitons Mollusca, Polyplacophora Second, revised edition. Backhuys, Rotterdam is a checklist of Chiton species, each with an original citation and current classification. The first volume appeared in , and to date five volumes have been published.

The treatise is rather scientific and uses high-quality line drawings instead of photographs to illustrate the species. Long out-of-print, but important regional literature dealing with the Polyplacophora are, A Monograph of the Australian Loricates Iredale, T. Hull Cotton , p. Special Publication No. The classic antiquariun work on worldwide Chitons is Pilsbry, H. Academy Natural Sciences, Philadelphia. These two volumes are part of a larger series of monographs on marine and land mollusks.
