Monroy, J.A.*; Nishikawa, K.C.: Aiming during prey capture in microhylid frogs Microhylid frogs have the unusual ability to aim their tongues independently of the head during prey capture. The tongue is elongated hydrostatically, which requires a novel protractor muscle (m. genioglossus) morphology. This novel morphology and demand for fine motor control raised the question: Are […]

HUSKEY, S.H.*; TURINGAN, R.G.: Variation in prey-resource utilization and oral jaw gape between two populations of largemouth bass, Micropterus salmoides. Ontogenetic changes in diet and jaw gape were compared between two populations of largemouth bass, Micropterus salmoides to test the hypothesis that ecomorphology varies among broadly distributed fish populations. Two hundred seventy-two temperate (southwest Michigan) […]

MCGOWAN, C.P.*; O’REILLY, J.C.; NISHIKAWA, K.C.: Scaling of the Feeding Mechanism in the Colorado River Toad There are several potential structural and functional consequences of an animal changing size. As the whole animal grows, individual components that make up complex functional systems, such as the feeding mechanism, may grow at varying rates. To explore this […]

DURIE, C.J.*; TURINGAN, R.G.: Relationship between durophagy and feeding functional design in marine fishes: intraspecific variation in ecological morphology The relationship between oral jaw biomechanics and consumption of hard prey was compared between populations of two perciform and five tetraodontiform species to examine intraspecific ecomorphological variation in marine fishes. Gut content analysis revealed that the […]

JANOVETZ, J.: Feeding in Serrasalmine Fishes: A Comparison of Suction and Biting Prey Capture Most fishes capture prey by suction feeding, rapidly expanding the oral cavity to create an inward flow of water that transports prey into the mouth. This type of prey capture is primitive for osteichthyes and has been the subject of considerable […]

Porter, H.T.*; Motta, P.J.: A Comparison of Prey Capture Behavior and Kinematics in Three Ram Feeding Fishes Ram feeding is the process by which a predatory fish uses a high-velocity lunge or chase to overtake its prey. This study compares the strike and prey capture behaviors and kinematics of three species of ram-feeding fishes: Florida […]

WILLINK, P.W.: The intertwining influences of prey, head shape, and attack behavior on gill raker morphology Gill rakers are believed to play a critical function during the feeding of fishes. The predominant view is that gill rakers strain prey from the medium. Long, closely-spaced gill rakers are correlated with feeding on small prey, whereas short, […]

CROLL, S.L.*; WATTS, S.A.: The effect of temperature on feeding characteristics in two sympatric crayfish species Crayfish are an integral component of many freshwater habitats. They often impact the environment through vegetative grazing, burrowing activities, and predation. The red swamp crayfish, Procambarus clarkii (PC), and the white river crayfish, P. zonangulus (PZ), are commonly found […]

Waltzek, T.B.*; Wainwright, P.C.: The Functional Morphology of Jaw Protrusion Among Neotropical Cichlids The evolution of protrusible upper jaws among acanthopterygian teleosts has long been argued a major factor contributing to the success of this extremely diverse group of fishes. Yet, few studies have investigated upper jaw protrusion in a comparative framework. Additionally, previously unstudied […]

SANDERSON, S.L.*; CHEER, A.Y.; GOODRICH, J.S.; GRAZIANO, J.D.; CALLAN, W.T.: How do gill rakers function in suspension-feeding fishes? Gill rakers have been assumed to serve as either (1) a sieve that accumulates particles larger than the mesh size or (2) a sticky filter that retains particles encountered via a hydrosol filtration mechanism. However, our video […]
