List of mammals of Heard Island and McDonald Islands

This is a list of the mammal species recorded in Heard Island and McDonald Islands. There are approximately 29 mammal species in Heard Island and McDonald Islands.This list is derived from the IUCN Red List which lists species of mammals and includes those mammals that have recently been classified as extinct (since 1500 AD). The taxonomy and naming of the individual species is based on those used in existing Wikipedia articles as of 21 May 2007 and supplemented by the common names and taxonomy from the IUCN, Smithsonian Institution, or University of Michigan where no Wikipedia article was available.

The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature:Unless stated otherwise the IUCN statuses for each species are based on global assessments. Many of the species (especially whales and dolphins) are migratory. EX Extinct No reasonable doubt that the last individual has died. EW Extinct in the wild Known only to survive in captivity or as a naturalized populations well outside its previous range. CR Critically endangered The species is in imminent risk of extinction in the wild. EN Endangered The species is facing an extremely high risk of extinction in the wild. VU Vulnerable The species is facing a high risk of extinction in the wild. NT Near threatened The species does not meet any of the criteria that would categorise it as risking extinction but it is likely to do so in the future. LC Least concern There are no current identifiable risks to the species. DD Data deficient There is inadequate information to make an assessment of the risks to this species.
