CARRENO, C. A.*; NISHIKAWA, K. C.; Northern Arizona University, Flagstaff; Northern Arizona University, Flagstaff: Does Xenopus laevis use suction for prey capture? Unlike most frogs, pipids are aquatic and capture prey underwater. For these aglossal frogs, the typical anuran mode of lingual prey capture is not possible. Because water is dense and viscous, suction feeding […]

RICE, Aaron N.; WESTNEAT, Mark W.; Univ. of Chicago; Field Museum of Natural History: Coordination of Feeding and Locomotor Systems in the Labridae To capture prey, fishes must coordinate complex movements of both the feeding and locomotor systems. Despite the extensive research on both systems in fishes, few studies have integrated these areas of study […]

Fundulus heteroclitus, a euryhaline teleost fish, inhabits marshes, bays, and estuaries along the Atlantic Coast of North America. Increases in the glucocorticoid hormone cortisol are thought to be […]
