Galapagos land snail  (Bulimulus akamatus)

This Galápagos land snail species is one of many tiny endangered bulimulid snails endemic to the Galápagos Islands, which often go unnoticed due to their small size (the largest species only reaching 25 mm in length) and dull brown colours (2) (3). This species has a reddish-brown, conical, spiralled shell.

Confined to the Galápagos Island of Santa Cruz, Ecuador (1). The species' range is restricted to the arid and transition vegetation zones of this island (4).

This species is mostly found under lava rocks and under the bark of Opuntia cacti (4).

Nothing is known of this Galápagos land snail's biology.

Since their colonisation, the Galapagos Islands have experienced a dramatic decline of suitable habitat for land snails, as farming, road and house construction, and eventually tourism, grew (1) (2) (3). Several species are now extinct and, of those remaining, many are endangered (2). Grazing livestock (goats, pigs) and invasive alien plants have also altered the snail's habitat (3) and, occasionally, the islands have suffered from uncontrolled fires, destroying habitat and snails alike (2). Additionally, introduced predators such as black rats (Rattus rattus) and little fire ants (Wasmania auropunctata) have had a direct impact on land snail populations by feeding on them and destroying their eggs (2).

There are currently no conservation measures targeting this species.
