List of mammals of Tuvalu

Pantropical spotted dolphins porpoising

This is a list of the mammal species recorded in Tuvalu. There are 3 mammal species in Tuvalu identified in the IUCN Red List, all of which are marine mammals of the order Cetacea: Ginkgo-toothed Beaked Whale (Mesoplodon ginkgodens), Pygmy Killer Whale (Feresa attenuata) and Pantropical Spotted Dolphin (Stenella attenuata).[1]

The literature review by Miller (2006) found 4 additional cetaceans reported: Orca or Killer whale (Orcinus orca), Spinner Dolphin (Stenella longirostris), Bottlenose Dolphin (Tursiops truncatus) and Sperm Whale (Physeter macrocephalus ).[2][3] The Pantropical Spotted Dolphin (Stenella attenuata) is found in the lists of both Miller and the IUCN. The Pacific ocean surrounding Tuvalu is within the range of these cetaceans although sightings of some of these species may be infrequent.

A revision of the list of cetaceans reported in the ocean surrounding Tuvalu was carried by Miller (2009),[4] who listed ‘minke-like’ whale (Balaenoptera sp.) and diminutive sperm whale (Kogia sp.).[4]

The following tags are used to highlight each species' conservation status as assessed by the IUCN:

DD Data Deficient There is inadequate information to make an assessment of the risks to this species.

Some species were assessed using an earlier set of criteria. Species assessed using this system have the following instead of Near Threatened and Least Concern categories:

LR/cd Lower Risk/conservation dependent Species which were the focus of conservation programmes and may have moved into a higher risk category if that programme was discontinued.
LR/nt Lower Risk/near threatened Species which are close to being classified as Vulnerable but are not the subject of conservation programmes.
LR/lc Lower Risk/least concern Species for which there are no identifiable risks.

Subclass: Theria

Infraclass: Eutheria

Order: Cetacea (whales)

Pantropical Spotted Dolphin

The order Cetacea includes whales, dolphins and porpoises. They are the mammals most fully adapted to aquatic life with a spindle-shaped nearly hairless body, protected by a thick layer of blubber, and forelimbs and tail modified to provide propulsion underwater.
