About Black caecilian
The Black caecilian, scientifically known as Ichthyophis monochrous, is an amphibian species belonging to the family Ichthyophiidae. It is native to the island of Borneo, specifically found in the northern regions. Its known distribution encompasses western Kalimantan in Indonesia and Sarawak in Malaysia, with a probable occurrence in Brunei as well.
Description and Habitat
This species is characterized by its moderately slender body. The holotype specimen recorded a length of 232 mm (9.1 inches) and a width of approximately 10 mm (0.39 inches). It possesses a distinct, short tail and visible eyes on its head. The skin of the Black caecilian is notably glandular and features a significant number of ring-shaped folds, numbering around 247. When alive, specimens have been observed to have a violet-brown coloration.
The Black caecilian is presumed to inhabit tropical moist forests. As adults, they are believed to lead a subterranean existence, spending much of their time burrowed beneath the surface. Due to its elusive nature and limited specimens documented, it remains a little-known species within its habitat.

Ichthyophiidae
The Ichthyophiidae, also known as Asiatic tailed caecilians or fish caecilians, are a primitive family of caecilians found across South and Southeast Asia and in southernmost China. They are distinguished by their tails, numerous body scales, and mouths that are not recessed, setting them apart from more derived caecilian families. Ichthyophiidae reproduce by laying eggs in moist soil, with larvae that develop in water before metamorphosing into terrestrial adults, and females may exhibit parental care.
Ichthyophis beddomei
Ichthyophis beddomei, also known as the yellow-striped caecilian, is a species of caecilian found in the Western Ghats of southern India. This fossorial amphibian is characterized by its dark violet-brown body contrasted with a distinctive yellow lateral stripe that runs from its head to the tail tip.
