Killer whales of the Saint-Paul and Amsterdam islands (southern Indian ocean) - Photo-identification catalogue 2024

The photo-identification catalogue includes images and associated data for the killer whale individuals encountered around the Amsterdam and Saint Paul islands (French Southern Lands) between 2007 and 2024.Individuals are represented by the best quality and most up to date photographs of the dorsal fin, saddle patch and eye patches, both for left and right sides when available. Individuals and their associated photographs are displayed on a two-page spread alongside others in their social unit, if confirmed (for frequently encountered whales) or otherwise assumed (for infrequently encountered whales). Social units were designated by the ID of the oldest female of the group (whether still alive or historically used to designate the unit) for the frequently encountered subset, or by the ID of the first identified female for other units with multiple members, or, for lone individuals by the ID of that individual.Additional information provided alongside names and photographs include the sex of individuals (with symbols ♀ or ♂, when known) as well as maternal relationships inferred from observed associative mother-offspring behaviour (solid lines linking a female to its offspring). For frequently encountered individuals their birth years (known or expressed with symbols ≤ or ~) are provided. Information on whether the individual was biopsied is indicated with the symbol “●” next to the ID.The date at which each identification photograph used in catalogues was taken, as well as the name of the photographer, were added to a table at the end of the catalogue.
