Acoustic analysis of airborne, underwater, and amphibious mother attraction calls by wild harbor seal pups (Phoca vitulina)
International audience Pinnipeds have great potential for comparative studies of mother–pup recognition due to the contrasting maternal strategies adopted by otariids and phocids. Typically, otariid mothers perform foraging trips during lactation, leaving their pups in the colony, whereas phocid mot...

International audience Pinnipeds have great potential for comparative studies of mother–pup recognition due to the contrasting maternal strategies adopted by otariids and phocids.
