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.
Hermit (hummingbird) notably SACC, which consider both "T. niger" and "T. leucurus" as valid species. Additionally, Mallet-Rodrigues (2006) suggested the taxon "loehkeni" should be considered a valid species, the bronze-tailed barbthroat. Three additional species, the tooth-billed hummingbird ("Androdon aequatorialis"), the green-fronted lancebill ("Doryfera ludovicae") and the blue-fronted lancebill ("D. johannae"), have been included in this subfamily in the past, but are now placed in "Trochilinae". Hermit (hummingbird) The hermits are tropical and subtropical hummingbirds in the subfamily Phaethornithinae, comprising 30–40 species in six genera. They occur from southern Mexico, through Central America, to South America as far south as northern Argentina. Their
