This Water Mite is probably a deutonymph rather than an adult. It was swimming in shallow water while being photographed. Could swim very fast. Part of its 'back' is above water in one photo. Ventral view is shown in one photo. Found with a dip net in the brook at Fogarty's Wetland. Before finding this, I never knew that aquatic arachnids existed.

I have been photographing bright orange/red versions of this in a large pond over several years. Would there be a place to look up the various species of these creatures?

There's a comprehensive list of Newfoundland's known water mite species listed in Chapter 14 of the NRCC publication "Assessment of Species Diversity in the Atlantic Maritime Ecozone". The relevant chapter is entitled, "Water mites (Acarina: Hydrachnidiae) of the Atlantic Maritime Ecozone". It begins on page 283. A portion of this publication is available on Google Books at:
