ABSTRACT
The subterranean mode of life always needs a high degree of biological adaptation. The cavernicolous species usually get selected from those which are preadapted with biological traits suitable for cave life and finally occupied a separate taxonomic status. With the ever going exploration of subterranean passages in Jaintia hills, till date several troglobitic species have been recorded from this particular area. Cave biota survey with respect to the explored subterranean passages of the area was conducted in February 2011. Krem Bylliat (cave) is one of them, measure horizontally 600 m having several openings. The cave is situated in the boundary of two major rock formations, nearer to one of the main tributary of river Kopili. Though, the cave is harbour of rich biodiversity, it was found to be relatively impoverished in terms of troglomorphic taxa. Possible factors, obviating the evolution of troglomorphy in this cave have been discussed.
