This OnLine laboratory manual  features original anatomical descriptions of 112 species for use in invertebrate zoology teaching or research laboratories in North America. The collection was prepared over a period of many years to facilitate and encourage the study of invertebrate animals.  It is a smorgasbord of species intended to provide a selection suitable for courses taught in most parts of North America. Many species,  or their close relatives, also occur in other parts of the world, especially Europe.  Although the chapters are written in laboratory manual format, they can also be used to support research or in other non-teaching situations as introductions to the anatomy of specific invertebrates .

Most of these descriptions are based on dissections of invertebrate animals collected in the Carolinas, Georgia, Florida, Maine, and Oregon beginning in 1980. A few are based on preserved material or commercially prepared slides. The collection is under ongoing revision and new species are added periodically.  The collection is sufficiently diverse to support undergraduate or graduate courses at most localities in North America. 

The anatomical descriptions are presented as laboratory exercises, many of which have been tested by my students in invertebrate zoology courses at Lander University, the Harbor Branch Oceanographic Institution, and the Duke University Marine Laboratory. These have benefited from numerous revisions based on many years of student use.

Emphasis is placed on the use of living anesthetized or freshly sacrificed, unpreserved specimens. Where possible species have been chosen that are readily available inexpensively and alive from supermarkets, bait shops, or seafood markets. Whenever possible  exotic (introduced) or commercially farmed species have been used in preference to natives.

Black and white line drawings are embedded in the texts.  Unless otherwise indicated the  illustrations are original. 

These accounts are copyrighted but unpublished. I would appreciate their receiving the same copyright considerations they would enjoy in print. You are encouraged to use them for your research or teaching but not for publication or commercial purposes.  I appreciate being informed and acknowledged when the exercises are used.  Email me at rsfox@lander.edu.

Terminology, phylogeny, and classification conform to usage in Ruppert EE, Fox RS, Barnes RB. 2004. Invertebrate Zoology, A functional evolutionary approach, 7th ed. Brooks Cole/Thomson, Belmont, CA. 963 pp + index. Page and chapter numbers in the following Table of Contents refer to this text. Pertinent figures from the text are indicated by callouts in the lab exercises.  In keeping with the incompatibility of Linnean categories with cladistics-based phylogeny, the use of those categories has been minimized, as it is in the aforementioned text.  For the benefit of those more comfortable with Linnean classifications, the traditional categories are indicated by superscript abbreviations (e.g. P = phylum, C = class, O = order, F = family, i = infra, s = sub, S = super) following the taxon name.
