Morphology, biology, and distribution of Ichthyophis kodaguensis (Amphibia:Gymnophiona), a rare caecilian from the Western Ghats, India

Abstract

Of the amphibian orders, the Gymnophiona (caecilians) have the lowest number of species and are the least known. We report new information on the morphology, biology, range, and distribution of Ichthyophis kodaguensis, a striped ichthyophiid caecilian from the Western Ghats, India that shows the first evidence of possible sexual-dimorphism in this species. Based on the clutch size, limited range, relatively low fecundity, and agricultural practices in their habitats, we consider that I. kodaguensis is highly threatened when compared to other striped ichthyophiids from the Western Ghats, a biodiversity hotspot.
