An unusual nursing interaction between two adult Cape fur seals Arctocephalus pusillus pusillus
Item type: Journal Article • Journal: African Journal of Marine Science • Authors: SP Kirkman --- Animal Demography Unit, Department of Zoology, South AfricaGiven 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... -
Recolonisation of the Robberg Peninsula (Plettenberg Bay, South Africa) by Cape fur seals
