Land Mammals

A Unique Biodiversity

Unlike any other U.S. National Park, the biota of Samoa stands apart, offering a unique glimpse into its vibrant and diverse ecosystems. While a few wide-ranging seabirds and marine fishes share similarities with other regions, the majority of the park’s species are strikingly different.

Native Land Mammals: A World of Bats

Samoa’s native land mammal population is limited to just three species of bats, which are integral to the health of the park’s ecosystems. These species include:

• Samoan Fruit Bat (Pteropus samoensis), a large, charismatic species often seen roosting in trees or soaring through the skies.
• White-naped Fruit Bat (Pteropus tonganus), another important pollinator and seed disperser for native plants.
• Sheath-tailed Bat (Emballonura semicaudata), a smaller, lesser-known species that plays a critical role in controlling insect populations.

For those used to encountering squirrels, deer, or other familiar mammals in mainland parks, the absence of these animals and the presence of bats as the sole native mammals offer a striking contrast. These bats are essential to the health of Samoa’s forests, acting as pollinators and seed dispersers that help maintain the park’s rich plant diversity.
