Ichthyophis longicephalus

Ichthyophis longicephalus, the long-headed caecilian, is known from Kerala, in Silent Valley National Park. The body is dark violet-brown and lighter underneath, with a yellow lateral stripe starting at the neck and reaching the tip of the tail, and small yellow patches on the sides of the neck (Wikipedia, general species account).

A midventral line formed by breaks in the annuli runs from the neck to the vent. The long head has distinct eyes and tentacles close to the lip and eye, and the nostrils sit at the snout tip, visible from above. The upper jaw overhangs the lower (Wikipedia, general species account).
