A legless lizard, which is also commonly known as a glass snake, is actually recognized as a species of lizard rather than as a snake.

In Thai, this reptile is referred to as jing lehn duang, which literally means ‘worm skink’, a compound of the words jing lehn and duang. This specific animal, overall grayish-black in colour, with a fine yellow line on its sides that run all along its length, was spotted in southern Vietnam, on the island of An Binh, and is known as the Yellow-striped Caecilian, which is scientifically referred to as Ichthyophis kohtaoensis.
