An unusual nursing interaction between two adult Cape fur seals Arctocephalus pusillus pusillus

Abstract

Given the high costs of lactation and the importance of milk for pup growth and survival in pinnipeds, nursing behaviour directed by a lactating female towards another adult is unexpected. Here, details were noted of a nursing interaction that occurred between two Cape fur seal Arctocephalus pusillus pusillus adults. After discussing the event in the light of various hypotheses that have been previously proposed to explain uncharacteristic nursing behaviour in pinnipeds, a mother–son relationship between the interacting pair was considered to be the most likely explanation.
