Feeding mechanics of teleost fishes (Labridae; Perciformes): A test of four‐bar linkage models
  • M. Westneat
  • Biology, Medicine
  • Journal of morphology
  • 1 September 1990
TLDR
A previously unidentified four‐bar chain was found to be an accurate model of the mechanism by which upper jaw protrusion, maxillary rotation, and gape increase occur in Cheilinus. Expand
A biomechanical model for analysis of muscle force, power output and lower jaw motion in fishes.
  • M. Westneat
  • Mathematics, Medicine
  • Journal of theoretical biology
  • 7 August 2003
TLDR
A lever model for the jaw of fishes that uses muscle design and the Hill equation for nonlinear length-tension properties of muscle to calculate dynamic power output and results show that simulations yield kinematics and timing profiles similar to actual fish feeding events. Expand
Exploring the radiation of a diverse reef fish family: phylogenetics of the damselfishes (Pomacentridae), with new classifications based on molecular analyses of all genera.
TLDR
A new classification scheme is provided wherein each subfamily is now monophyletic, and this reorganization is consistent with all previous molecular studies of the damselfishes. Expand
Phylogenetic relationships and evolutionary history of the reef fish family Labridae.
TLDR
A phylogenetic analysis of labrids was conducted to investigate relationships among the six classical tribes of wrasses, the affinities of the wrasses to the parrotfishes (scarines), and the broad phylogenetic structure among labrid genera, confirming the monophyly of a family Labridae that includes the parrots and butterfishes and strong support for many previously identified taxonomic subgroups.

Evolution of Levers and Linkages in the Feeding Mechanisms of Fishes1
  • M. Westneat
  • Biology, Medicine
  • Integrative and comparative biology
  • 1 November 2004
TLDR
This study examines the diversity of mechanical design of the oral jaws in 35 species of ray-finned fishes to analyze lower jaw lever models in a broad phylogenetic range of taxa and identify the origin and evolutionary patterns of change in the linkage systems that power maxillary rotation and upper jaw protrusion. Expand
EVOLUTIONARY HISTORY OF THE PARROTFISHES: BIOGEOGRAPHY, ECOMORPHOLOGY, AND COMPARATIVE DIVERSITY
TLDR
The phylogenetic results imply an East Tethyan origin of the Scaridae and the recurrent evolution of excavating and scraping feeding modes, and a two‐phase model of parrotfish evolution to explain patterns of comparative diversity. Expand
Mechanical performance of aquatic rowing and flying
  • J. Walker, M. Westneat
  • Medicine, Engineering
  • Proceedings of the Royal Society of London…
  • 22 September 2000
TLDR
A computer simulation to compare the mechanical performance of rowing and flapping appendages across a range of speeds proved to be more mechanically efficient than rowing appendages at all swimming speeds, suggesting that animals that frequently engage in locomotor behaviours that require energy conservation should employ a flapping stroke. Expand
Transmission of force and velocity in the feeding mechanisms of labrid fishes (Teleostei, Perciformes)
TLDR
The feeding mechanisms of four species of the teleostean family Labridae were modeled using four-bar linkage theory from mechanical engineering to calculate the capacity for transmission of force and velocity in musculoskeletal systems. Expand
Molecular phylogenetics of the butterflyfishes (Chaetodontidae): taxonomy and biogeography of a global coral reef fish family.
TLDR
The species-level phylogeny for the butterflyfishes is used to resolve long-standing questions regarding the use of subgenera in Chaetodon, to reconstruct molecular rates and estimated dates of diversification of major butterflyfish clades, and to examine global biogeographic patterns. Expand
A Functional morphospace for the skull of labrid fishes: patterns of diversity in a complex biomechanical system
TLDR
It is hypothesized that the functional and ecological diversity of labrids is due in part to a history of decoupled evolution of major components of the feeding system as well as among the muscular and skeletal elements of each component. Expand
