List of mammals of Tuvalu


This is a list of the mammal species recorded in Tuvalu. There are three mammal species in Tuvalu identified in the IUCN Red List, all of which are marine mammals of the order Cetacea: ginkgo-toothed beaked whale, pygmy killer whale, and pantropical spotted dolphin.
The literature review by Miller found four additional cetaceans reported: orca or killer whale, spinner dolphin, bottlenose dolphin, and sperm whale. The pantropical spotted dolphin is found in the lists of both Miller and the IUCN.
A revision of the list of cetaceans reported in the ocean surrounding Tuvalu was carried out by Miller, who listed a "minke-like" whale and a diminutive sperm whale.
In 2010 a research voyage was conducted within the exclusive economic zones of Kiribati and Tuvalu. The survey confirmed the presence of seven species of cetaceans: sperm whale, killer whale, Bryde's whale, short-finned pilot whale, false killer whale, spinner dolphin, and striped dolphin.
The Pacific Ocean surrounding Tuvalu is within the range of these cetaceans although sightings of some of these species may be infrequent.
The following tags are used to highlight each species' conservation status as assessed by the International Union for Conservation of Nature:
