R. Aidan Martin and Anne Martin

R. Aidan Martin and Anne Martin are a husband-and-wife team of marine biologists based in Vancouver, Canada. Aidan, who specializes in the behavioral ecology of sharks and rays, is director of the ReefQuest Centre for Shark Research (www.elasmo-research.org); a research associate in the zoology department of the University of British Columbia, in Vancouver; and an adjunct professor at the Oceanographic Center of Nova Southeastern University, in Dania Beach, Florida. He is the author of Field Guide to the Great White Shark (ReefQuest Centre for Shark Research, 2003) and is at work on a book about shark behavior for Cambridge University Press. Anne, a salmon biologist with Fisheries and Oceans Canada, is also an underwater and topside photographer and videographer. She assists Aidan in his field research, lends a hand when he teaches field courses in shark biology and coral reef ecology, prepares graphics for his scientific and educational presentations, edits his writings, and permits him to dissect sharks in their kitchen.
