| evolution and mechanics of long jaws in butterflyfishes (family chaetodontidae). | we analyzed the functional morphology and evolution of the long jaws found in several butterflyfishes. we used a conservative reanalysis of an existing morphological dataset to generate a phylogeny that guided our selection of seven short- and long-jawed taxa in which to investigate the functional anatomy of the head and jaws: chaetodon xanthurus, prognathodes falcifer (formerly chaetodon falcifer), chelmon rostratus, heniochus acuminatus, johnrandallia nigrirostris, forcipiger flavissimus, and ... | 2001 | 11304744 |
| sound pressure enhances the hearing sensitivity of chaetodon butterflyfishes on noisy coral reefs. | butterflyfishes are conspicuous members of coral reefs that communicate with acoustic signals during social interactions with mates and other conspecifics. members of the genus chaetodon have a laterophysic connection (lc) - a unique association of anterior swim bladder horns and the cranial lateral line - but the action of the lc system on auditory sensitivity is unexplored. here, we show in baseline auditory evoked potential threshold experiments that forcipiger flavissimus (which lacks swim b ... | 2015 | 25722003 |
| specialist corallivores dominate butterflyfish assemblages in coral-dominated reef habitats. | this study examined the dietary habits and functional composition of butterflyfishes in the chagos archipelago, central indian ocean. eighteen species of butterflyfishes were recorded in chagos, including six obligate corallivores (chaetodon bennetti, chaetodon guttatissimus, chaetodon meyeri, chaetodon trifascialis, chaetodon trifasciatus and chaetodon zanzibarensis), five facultative corallivores (chaetodon auriga, chaetodon falcula, chaetodon interruptus, chaetodon kleinii and chaetodon madag ... | 2013 | 23557298 |
| a new species of aponurus looss, 1907 (digenea: lecithasteridae) in butterflyfishes (perciformes: chaetodontidae) from new caledonia. | aponurus chelebesoi n. sp. is described from chaetodon auriga, c. citrinellus, c. ephippium, c. flavirostris, c. lineolatus, c. melannotus, c. mertensii, c. pelewensis, c. lunulatus, c. vagabundus, coradion altivelis, forcipiger flavissimus, heniochus acminatus, h. chrysostomus and h. monoceros from the southern coast of new caledonia. it is distinguished from most species in the genera aponurus (synonym brachadena) and lecithophyllum by its claviform (as opposed to oval to subglobular) vitellin ... | 2000 | 10845650 |
| diversity and evolution of sound production in the social behavior of chaetodon butterflyfishes. | fish produce context-specific sounds during social communication, but it is not known how acoustic behaviors have evolved in relation to specializations of the auditory system. butterflyfishes (family chaetodontidae) have a well-defined phylogeny and produce pulsed communication sounds during social interactions on coral reefs. recent work indicates that two sound production mechanisms exist in the bannerfish clade and that other mechanisms are used in the chaetodon clade, which is distinguished ... | 2015 | 25805700 |
| sound production in the longnose butterflyfishes (genus forcipiger): cranial kinematics, muscle activity and honest signals. | many teleost fishes produce sounds for social communication with mechanisms that do not involve swim bladder musculature. such sounds may reflect physical attributes of the sound-production mechanism, be constrained by body size and therefore control signal reliability during agonistic behaviors. we examined kinematics of the cranium, median fins and caudal peduncle during sound production in two territorial chaetodontid butterflyfish sister species: forcepsfish (forcipiger flavissimus) and long ... | 2011 | 22031748 |
