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.
Great-billed hermit Great-billed hermit The great-billed hermit ("Phaethornis malaris") is a species of hummingbird in the family Trochilidae. It is found in Bolivia, Brazil, Colombia, Ecuador, French Guiana, Peru, Suriname, and Venezuela. Its natural habitat is subtropical or tropical moist lowland forest. The taxonomy of this species and the long-tailed hermit is confusing. Most taxa previously consider subspecies of the latter ("insolitus", "moorei", "ochraceiventris", "bolivianus" and "margarettae") are now considered subspecies of the former. A satisfactory taxonomic treatment of the entire "P. longirostris/P. superciliosus/P. malaris" group is still lacking according to some Neotropical ornithologists. Additionally, the taxon "margarettae" of the Atlantic Forest
