Polarization vision and its role in biological signaling (2003)

Cronin, Thomas W., Shashar, Nadav, Caldwell, Roy L., Marshall, Justin, Cheroske, Alexander G., Chiou, Tsyr-Huei

Visual pigments, the molecules in photoreceptors that initiate the process of vision, are inherently dichroic, differentially absorbing light according to its axis of polarization. Many animals have...

Two living species of coelacanths?

Holder, Mark T., Erdmann, Mark V., Wilcox, Thomas P., Caldwell, Roy L., Hillis, David M.

During the period of September 1997 through July 1998, two coelacanth fishes were captured off Manado Tua Island, Sulawesi, Indonesia. These specimens were caught almost 10,000 km from the only other...

Individually Unique Body Color Patterns in Octopus (Wunderpus photogenicus) Allow for Photoidentification

Huffard, Christine L., Caldwell, Roy L., DeLoach, Ned, Gentry, David Wayne, Humann, Paul, MacDonald, Bill, ...

Studies on the longevity and migration patterns of wild animals rely heavily on the ability to track individual adults. Non-extractive sampling methods are particularly important when monitoring...
