The Frigate Island caecilian (Hypogeophis rostratus) is a species of amphibians in the family Indotyphlidae, endemic to Seychelles, where it is the most widespread caecilian species. It is found on all the islands with amphibians, namely Mahé, Praslin, Silhouette, Ste. Anne, Curieuse, La Digue, Cerf, and Frégate. The Frigate Island caecilian skeletal structure said to resemble the Gegeneophis ramaswamii, an Indian direct-developing caeciliid (Müller, 2006). This discovery was made after many people questioned the original statements made regarding their skeletal structure and how it develops.
