Interactive Parasitology

Introduction Major Groups Credits More Information


The main objective of this multi-media program is to expose you in a novel and interactive manner to representative examples illustrating the rich diversity of parasitic organisms from the Pacific Northwest.

Lironeca californica

The still photograph and the video clip show the large parasitic isopod, Lironeca californica on the head region of its fish host, the shiner perch, Cymatogaster aggregata

The parasite species selected include primarily examples obtained using live video photomicroscopy. This footage was obtained by students during field trips to the Bamfield Marine Station or during parasitology/ invertebrate zoology laboratory classes in the Department of Biology at Malaspina University-College, Nanaimo, British Columbia.

Parasites: The Major Groups

When this program is complete it will include representatives of each of the major groups of parasitic organisms as illustrated on the button box. This Web summary is confined to the Arthropods group. The original presentation is on a CD-ROM, authored using Asymetrix Toolbook.

The Arthropoda constitute an enormous phylum. Thus it is not surprising that many groups have exploited the parasitic lifestyle, spending a portion of their life attached to a host. Familiar examples include representatives of the Arachnida (e.g. ticks and mites), the Insecta (e.g. fleas and lice) and the Crustacea (e.g. copepods, isopods and barnacles). We will focus on Crustacea, for it is among the ectoparasitic crustaceans infecting marine vertebrates and invertebrates that we see among the most highly modified and bizarre animals.

This chapter is designed to illustrate some of this diversity by examining the morphological and life-cycle adaptations of representative marine crustaceans found on, primarily, fish collected from the Bamfield Marine Station.
