Uraeotyphlus interruptus

Asia·Oviparous with terrestrial eggs and aquatic larvae·Not Evaluated·Western Ghats, southern India (Kerala)

Uraeotyphlus interruptus, also known as the Chengalam caecilian, is a medium-sized caecilian species endemic to the Western Ghats of southern India. It is distinguished by its slaty violet coloration with white lines marking its body folds and its specific pattern of dorsal and ventral annuli. This fossorial species is primarily found in loose soil, likely within moist evergreen forests, and is presumed to have a reproductive strategy involving terrestrial eggs and aquatic larvae.

Key Facts

  • Endemic to the Western Ghats of southern India, specifically the Chengalam village in Kerala.
  • Measures approximately 185 MM (7.3 inches) in length.
  • Features 162 body folds, with primary annuli crossing the dorsum only on the posterior half and venter only in front of the vent.
  • Has a slaty violet coloration above, becoming slightly lighter on the underside, with conspicuous white lines on body folds.
  • Presumed to be oviparous with terrestrial eggs and aquatic larvae that inhabit streams.
  • Associated with loose soil and a subterranean (fossorial) lifestyle, likely within moist evergreen forests.

Habitat

Moist Evergreen Forest, Loose Soil, Subterranean

Physical Description
Uraeotyphlus interruptus is a medium-sized caecilian, reaching a length of approximately 185 mm (7.3 inches). It possesses 162 distinct body folds. The primary annuli, which are characteristic rings around the body, extend across the dorsum only in the posterior half and on the venter only anterior to the vent. The collar region is slightly broader than the head, with the two collars completely fused dorsally but separate ventrally. The eyes are clearly visible, and the ventral tentacle is situated below the nostril. Its coloration is a slaty violet on the upper side, becoming slightly lighter on the underside. The body folds are accentuated by white lines, which are particularly noticeable on the posterior one-third of the ventral side of the body.

About Uraeotyphlus interruptus

Uraeotyphlus interruptus: The Chengalam Caecilian

Uraeotyphlus interruptus, commonly referred to as the Chengalam caecilian, is a species of caecilian belonging to the family Ichthyophiidae. It is a fascinating amphibian endemic to the Western Ghats mountain range in southern India, with its known existence currently confined to the type locality of Chengalam village in the state of Kerala.

Description and Habitat

This medium-sized caecilian typically measures around 185 mm (7.3 inches) in length and is characterized by its distinctive slaty violet coloration, which is slightly lighter on its underside. White lines mark its numerous body folds, numbering 162, and are particularly conspicuous on the posterior ventral third of its body. Uraeotyphlus interruptus is a subterranean, or fossorial, species, meaning it lives a life largely beneath the surface in loose soil. While the specimens were collected in a rubber plantation, it is presumed that its natural habitat consists of moist evergreen forests. The species exhibits specific patterns in its body annuli, with primary rings crossing the dorsum only on the posterior half and the venter only in front of the vent. The collar region is slightly wider than the head and is fused dorsally but distinct ventrally. Its eyes are clearly discernible, and a ventral tentacle is located below the nostril.

Reproduction and Conservation

The reproductive strategy of Uraeotyphlus interruptus is not fully documented but is presumed to be oviparous, involving terrestrial eggs and aquatic larvae that inhabit streams. Specific threats to this species are currently unknown, and it is noted for being somewhat adaptable, suggesting it may not face significant threats from habitat alteration. However, it is not known to inhabit any protected areas, which could pose a future risk to its survival. Further research is needed to fully understand its ecological role and conservation needs.
