Periclimenes dardanicola chiefly white, with red along the edges of the carapace and the abdominal somites. The legs are transparent yellow, with red bands. "P. dardanicola" is associated with the sea anemone "Calliactis", which is carried by hermit crabs of the genus "Dardanus", including "Dardanus arrosor", "D. crassimanus", "D. lagopodes" and "D. pedunculatus". This is one of the few examples of ecological associations between two species of decapod crustaceans. Specimens of "Periclimenes dardanicola" have been collected from various locations in the western Pacific Ocean, namely Suruga Bay (Japan), Vietnam, and Borneo (Indonesia). Although only formally described in 2006, this species has been
Hermit (hummingbird) very decurved bills. Many species, including the rufous-breasted hermit, also use the heliconias for nesting, attaching their conical nest to the underside of one of the plant's broad leaves. The taxonomy of some groups has changed significantly in recent years. Apart from those issues discussed at "Phaethornis", a taxonomic problem occurs with the "Threnetes leucurus"/"T. niger" complex. Schuchmann & Hinkelmann (1999) considered the sooty barbthroat a melanistic variant of the "T. leucurus", but as it was described first, its scientific name was adopted for the entire species; pale-tailed barbthroat ("T. niger"). This, however, has not been accepted by all authorities,
