Fiddler ray snouts are translucent. The fiddler rays are also distinguished from other guitarfishes in that the anterior nasal flaps of their nostrils are expanded backwards and fused together into a nasal curtain that reaches the mouth. Fiddler rays feed on bottoms shellfish, crabs, and worms, which they crush between their jaws. The eastern fiddler ray is known to scavenge from fish traps. Like other guitarfishes, fiddler rays are ovoviviparous. The egg capsules of the southern fiddler ray are reported to be golden in colour, containing three embryos each. It gives birth to litters of four to six young per breeding cycle.

This species is commonly referred to as the eastern long-tailed hermit, but it is likely, following recommendations from Gary Stiles in February 2006, that the new name will be adopted by most authorities. The taxonomic history of this group is complicated, with similar hermit populations from both sides of the Andes being originally classed as a single long-tailed hermit species. The western population was then split as the western long-tailed hermit, "P. longirostris", leading to the renaming
