The aquarium facility for housing adult and juvenile mussels in my laboratory:

Description: \\acfiles\www-home\Aquarium3.jpgDescription: \\acfiles\www-home\Aquarium4.jpg

Chambers housing juveniles in a down-welling system (left) and adult U.imbecillis releasing glochidia larvae (visible as mucous strands from exhalant siphons).

Glochidia larvae of the mussel Utterbackia imbecillis with the adductor muscle stained with a fluorochrome that binds to actin filaments. The valves are fully open. Larvae are about 280 microns in length (axis parallel to the hinge).

Description: \\acfiles\www-home\juvie10.jpg

Larva at day-4 of metamorphosis (upper left), with adductor muscle gone. Juvenile (upper right) 7 days post-metamorphosis showing new anterior and posterior adductor muscles. The first 3 pairs of gills filaments are partially visible (especially to the right of the mid-central foot). Lower image is of a juvenile 10 days post-metamorphosis, showing brightly fluorescing adductor muscles, some pedal musculature (center) and the heart within the pericardial sinus (toward 4 o'clock, just right of center of image, near posterior adductor).

3-week old juvenile Pyganodon cataracta : anterior to the right, total length about 450 microns; subtriangular part of shell is original larval shell; brownish-green is silt and algae in stomach and digestive glands.

Description: \\acfiles\www-home\Juvies.jpg
Juvenile P. cataracta : about 5 weeks old. Individual on right is about 700 microns. Note new shell growth flanking foot on animal at right.

Description: \\acfiles\www-home\cat4a.jpg
10 week old P. cataracta approximately 3.5 mm long, showing well developed inhalant and exhalant siphons. Animal is in process of rejecting a mass of yellow latex beads that it has filtered out of suspension.

Same juvenile as above showing a plume of latex beads in the flow from the exhalant siphon.

Web site devoted to Arachnology which of course includes the study of the Acari, the Order of mites, ticks, etc.
 

Mussel/mollusc related web sites:
 

Check out UNIO, a Listserver for anyone interested in the biology of freshwater mussels.

The Freshwater Mussel Conservation Society web site is an excellent source of information, with a lot of great links to useful resources on the web.

A nice molluscan resource site developed by Deborah Wills

A terrific gallery of mussel images maintained by Chris Barnhart, Unio Gallery

Home Page of the American Microscopical Society AMS, a great place for Invertebrate Biologists to gather.
