Relevant Information:

Differs from from other species in this genera by having three pairs of barbels, one pair of maxillary and two pairs of mandibular. Inhabits fast flowing river, canals and streams (mostly hides in holes on rocks) where it feeds on small fishes and crustaceans (Arunachalam et al. 2000). It is nocturnal and highly reclusive during the day hiding in pools (Gopi and Radhakrishnan 2001). During its spawning seasons (monsoon months), the fish often comes to shallow water in submerged cultivable fields amidst the riparian vegetation for spawning during night and returns to the stream habitats before dawn (Gopi and Radhakrishnan 2001). Remarks: Pterocryptis wynaadensis is assessed as Endangered and is on the IUCN Red List of Threatened Species in view of an inferred 50-60% decline in the overall population over the past 10 years resulting from habitat loss, destructive fishing practices and pollution from domestic and agricultural sources.
