Canadian Amphibian and Reptile Conservation Network - Réseau Canadien de Conservation des Amphibiens et des Reptiles
Key to Cheloniidae (Marine Turtles)

No sea turtle nests or spends much of its time in Canadian
waters.   
However a number of species may feed along the coasts of British
Columbia  
or the Maritimes.  It is possible that other species may occasional
swim   
into Canadian waters.  Such sightings (especially if photographs
are   
available) should be reported to a local museum.  
  
Choose the description that best fits the animal of interest.  
If none fit go back to previous page.
