Description
Holotype: ZMB, collection number unknown, “Seychelles Islands”, collected in 1913 by A. Mérian.

Approximately 200 mm in length; primary folds more numerous than secondaries; 5-6 premaxillary teeth, 8-11 maxillary teeth; small tentacle that is nearer to the eye than the nostril; circular gill clefts present in adults (modified from Taylor 1968).

Seychelles Islands: Mahé, Silhouette, Praslin, La Digue.

Typically all Grandisonia species are fossorial and can be found under leaves, stones, decaying wood, and in wet soil. G. larvata is known from sea-level to at least 260 m. Distribution is thought to be limited to the availability of moist habitat rather than elevation.

Life History, Abundance, Activity, and Special Behaviors
Grandisonia larvata is probably best considered uncommon.

All species of Grandisonia are believed to be oviparous. It has been reported that G. larvata has a larval stage.

Trends and Threats
A permit is required for their collection. They are potentially endangered by habitat destruction.

Possible reasons for amphibian decline

General habitat alteration and loss
Habitat modification from deforestation, or logging related activities
