Description – Galapagos land snail
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 dark brownish-black, conical, spiralled shell, tinted with red.
Habitat – Galapagos land snail
Found in arid to transition zones, typically under rocks or on tree trunks (1).
Biology – Galapagos land snail
Nothing is known of this Galápagos land snail’s biology.
Threats – Galapagos land snail
Since its colonisation in 1920, the human population on Santa Cruz has multiplied dramatically, leading to the decline of suitable habitat for land snails as farming and road and house construction grew (1) (2). In addition, habitat alteration and introduced species of plants and animals are also thought to have had a negative impact (1) (3).
Conservation – Galapagos land snail
There are currently no conservation measures targeting this species.
