Journal ArticleDOI
Aquatic–terrestrial transitions of feeding systems in vertebrates: a mechanical perspective
TL;DR: Any aquatic vertebrate aiming for a terrestrial lifestyle must change from its aquatic to a terrestrial feeding mechanism, and the mechanical challenges associated with such aquatic–terrestrial transitions in vertebrates are synthesized.
Journal ArticleDOI
Conserved spatio-temporal patterns of suction-feeding flows across aquatic vertebrates: a comparative flow visualization study.
Corrine N. Jacobs,Roi Holzman +1 more
TL;DR: Flow visualization reveals that suction flow speeds increase with mouth diameter, whereas other flow characteristics remain conserved across aquatic vertebrates, and concludes that trophic diversity is not supported by variation in suction flows.

Food Capture in Vertebrates: A Complex Integrative Performance of the Cranial and Postcranial Systems
TL;DR: The goal of this chapter is to inspire and promote future research on integration in order to extend the concept of food capture, and feeding behavior in general, beyond the cranial system in a more holistic approach to function.
Journal ArticleDOI
Functional morphology of terrestrial prey capture in salamandrid salamanders.
TL;DR: Functional trade-offs of the hyobranchial apparatus result in lower tongue-projection distance, velocity, acceleration and power in semi-aquatic and aquatic salamandrids compared with terrestrial specialists.
Journal ArticleDOI
Thermodynamics of the Bladderwort Feeding Strike—Suction Power from Elastic Energy Storage
TL;DR: Estimates of elastic energy storage and frictional losses during suction events support the hypothesis that small suction feeders convert a large proportion of the elastic energy stored in the trap walls into kinetic energy of the inspired water, with little energy thermalized due to friction.

Suction feeding mechanics, performance, and diversity in fishes
Peter C. Wainwright,Andrew M. Carroll,David C. Collar,Steven W. Day,Timothy E. Higham,Roi Holzman +5 more
TL;DR: The model indicates that the pressure gradient in front of a fish that is feeding by suction, associated with the gradient in water velocity, results in a force on the prey that is larger than drag or acceleration reaction, even when other features of the suction flow are held constant.

Tongue evolution in the lungless salamanders, family Plethodontidae. II. Function and evolutionary diversity.
R. Eric Lombard,David B. Wake +1 more
TL;DR: A recently presented model of tongue projection dynamics is used to generate a series of predictions concerning morphologies to be expected under selection for increased distance of projection, increased speed of projections, and increased directional versatility.
Journal ArticleDOI
Multidimensional analysis of suction feeding performance in fishes: fluid speed, acceleration, strike accuracy and the ingested volume of water
TL;DR: A multidimensional perspective on suction feeding performance is presented and it is suggested that species that generate high fluid speeds in the earthbound frame of reference will commonly exhibit small mouths and a high capacity to deliver force to buccal expansion, while species that ingest a large volume of water and generate high volumetric flow rates will have larger buCCal cavities and cranial expansion linkage systems that favor displacement over force delivery.
Journal ArticleDOI
Spatial and temporal patterns of water flow generated by suction-feeding bluegill sunfish Lepomis macrochirus resolved by Particle Image Velocimetry.
TL;DR: Comparison of the time-resolved fluid velocity measurements to gape kinematics demonstrate that peak fluid speed occurs simultaneously with 95% of peak gape, showing that the bluegill maximizes nearly simultaneously both the generated forces and size of the region over which these forces act.

Functional morphology of the feeding mechanism in aquatic ambystomatid salamanders
TL;DR: This study addresses four questions in vertebrate functional morphology through a study of aquatic prey capture in ambystomatid salamanders: how does the feeding mechanism of aquatic salamander function as a biomechanical system, what are the major structural and functional patterns in the evolution of the lower vertebrate skull?
