WILLIAMS, S.H.*; WALL, C.E.; VINYARD, C.J.; HYLANDER, W.L.; Duke University, Durham, NC; Duke University, Durham, NC; Duke University, Durham, NC; Duke University, Durham, NC: Jaw-muscle motor patterns in ungulates: is there a transverse pattern? Similarities in masticatory apparatus form and jaw movements in artiodactyls and perissodactyls have led to the idea that ungulate grinding is […]

O’NEILL, M.W.*; GIBB, A.C.; Northern Arizona University; Northern Arizona University: Feeding and Respiration in Trinectes maculatus: Half a head is better than one Flatfishes have evolved a benthic lifestyle, where both eyes are present on one side of the head as adults. This results in marked morphological asymmetry, especially in the head and mouth. Hogchokers, […]

MCCAY, M.G.*; WAINWRIGHT, P.C.; DWYER, H.A.; CHEER, A.Y.; Univ. of California, Davis; Univ. of California, Davis; Univ. of California, Davis; Univ. of California, Davis: New Insights Into Suction Feeding from a Computational Fluid Dynamic Model Suction feeding is the most commonly used mechanism of prey capture in fishes and other aquatic vertebrates, but little is […]

PADILLA, D.K.; State University of New York, Stony Brook: Inducible offenses in a marine snail: phenotypic plasticity in feeding structures, food preferences, and dispersal potential. Although the ecological and evolutionary consequences of inducible defenses have gained a great deal of attention by scientists, inducible offenses have had considerably less attention. Like inducible defenses, inducible offenses […]

DEAN, M.N.; MOTTA, P.J.; Univ. of S. Florida; Univ. of S. Florida: Hoover vacuums and scissor jacks: A novel jaw protrusion mechanism in batoids Protrusion of the jaws during feeding is common in members of the Batoidea (rays, skates, sawfishes and guitarfishes), members of which possess a highly modified jaw suspension. The lesser electric ray […]

BEATTY, B. L.; Howard University, Washington, DC: Cornwallius sookensis (Desmostylia, Mammalia): New Material and its Implications for Suction Feeding Cornwallius sookensis is one of the oldest known members of the extinct Order Desmostylia, a group traditionally interpreted as semiaquatic and hippo-like because of their resemblances to Hippopotamus and to their close tethytherian cousins, Moeritherium (a […]

CUNDALL, David; FORD, Neil; Lehigh University; University of Texas, Tyler: Xenopeltis unicolor: Evolution of Unilateral Jaw Motion and Macrostomy in Snakes. Xenopeltis, a snake with unusual skull and cephalic muscle forms, is currently hypothesized to be a basal macrostomatan. Clade membership of Xenopeltis is reassessed on the basis of prey capture and transport mechanics, manipulations […]

FERRY-GRAHAM, LA; WAINWRIGHT, PC; NEAR, TJ; UC Davis; UC Davis; UC Davis: Pharyngeal Jaw Form, Function, and Evolution in the Labroidei The teleost clade Labroidei (labrids, cichlids, pomacentrids + embiotocids) is characterized as having functional and morphological novelties associated with the pharyngeal jaw apparatus (PJA); most notably extension and fusion of muscles to form a […]

PRATT, M.C.; Duke University, Durham, NC: It�s where you put your mouth that matters: how the location of feeding zooids within a colony affects ingestion rate in bryozoans. While there is a wide diversity of colonial animals, very similar colony growth forms seem to have evolved convergently across taxa. Is there a functional reason why […]

WILGA, Cheryl/D.; Univ. of Rhode Island: Evolution of the Jaw Suspension in Lamniform Sharks Morphological characters of the jaw suspension and jaw muscles of lamniform sharks were mapped onto a cladogram to shed light on how changes in jaw suspension and protrusion may have evolved. Several evolutionary changes in the jaw suspension and protrusion mechanism […]
