Meeting Abstract 38.5  Saturday, Jan. 5  The Contributions of Sensory Morphology and Prey Detection Behavior to Trophic Niche Differentiation in Two Sand-Feeding Lake Malawi Cichlids SCHWALBE, M.A.B.*; WEBB, J.F.; University of Rhode Island; University of Rhode Island mbergstrom@my.uri.edu The adaptive radiations of African cichlids resulted in a diversity of feeding morphologies and strategies, but the role of […]

Meeting Abstract 38.3  Saturday, Jan. 5  Sensory switching in sharks: the role of multimodal stimuli in prey tracking and capture GARDINER, JM*; ATEMA, J; HUETER, RE; MOTTA, PJ; Mote Marine Laboratory; Boston University; Mote Marine Laboratory; University of South Florida jayne@mote.org Hunting involves a sequence of steps with increasing sensory information as the distance between predator and […]

Meeting Abstract 38.2  Saturday, Jan. 5  Sensory signals and predator search performance at the low prey density limit HEIN, A. M.*; MCKINLEY, S. A.; University of Florida; University of Florida amhein@ufl.edu Organisms of all types collect sensory measurements from their environments. In some cases, these measurements contain information about the locations of resources such as prey. We […]

Meeting Abstract 38.4  Saturday, Jan. 5  Coexpression of Spectrally Distinct Opsins: A Novel Mechanism of Photoreceptor Tuning? DALTON, B. E. *; CRONIN, T. W.; CARLETON, K. L.; University of Maryland, Baltimore County briand7@gmail.com Detection of predators is a critical task that many animals accomplish visually. Because predators often appear as dark objects, their detection can be facilitated […]

Meeting Abstract 38.7  Sunday, Jan. 5 09:30  Visual opsins in non-visual photoreceptors: A common solution for extraocular light detection KINGSTON, A*; CRONIN, T; Univ. of Maryland, Baltimore County; Univ. of Maryland, Baltimore County anahm1@umbc.edu Non-visual photoreceptors are common throughout the animal kingdom. Most previously described non-visual photoreceptors function using opsins that are not typically used for vision. […]

Meeting Abstract 38.1  Sunday, Jan. 5 08:00  The role of the lateral line system in foraging by zebrafish larvae CARRILLO, A.*; GARCIA, D.A.; MCHENRY, M.J.; Univ. of California, Irvine; Cerritos College; Univ. of California, Irvine andresc2@uci.edu Adult fish use the lateral line system to localize prey by sensing water flow, but it is unclear when this ability […]

Meeting Abstract 38.6  Sunday, Jan. 5 09:15  Seeing double: the ontogeny of light sensitivity in stomatopod crustaceans FELLER, KD*; COHEN, JH; CRONIN, TW; University of Maryland Baltimore County kfeller1@umbc.edu In addition to having unique adult visual systems, stomatopod crustaceans also undergo a unique process of eye development. Just prior to metamorphosis, an adult retina and associated neuropils […]

Meeting Abstract 38.5  Sunday, Jan. 5 09:00  Photoreceptors with dual sensitivity to UV and visible light are in the larval eyes of the basal arthropod Limulus polyphemus BATTELLE, B-A.*; KEMPLER, K.E.; PAYNE, R.; Whitney Lab. Univ. of Florida; Whitney Lab. Univ. of Florida; Univ. of Maryland, College Park battelle@whitney.ufl.edu Limulus is a classic model for studies of […]

Meeting Abstract 38.3  Sunday, Jan. 5 08:30  Morphology and ontogeny of multiple lateral line canals in the prickleback genus Xiphister (Cottiformes: Zoarcoidei: Stichaeidae) CLARDY, T*; HILTON, EJ; VOGELBEIN, WK; Virginia Institute of Marine Science tclardy@vims.edu Several members of the prickleback family Stichaeidae have multiple, complexly branching trunk lateral line canals that are supported by small, dermal, ring-like […]

Meeting Abstract 38.4  Sunday, Jan. 5 08:45  Energetics of active sensory and communication signals in the weakly electric fish Eigenmannia virescens: Organismal, cellular, and molecular perspectives. MARKHAM, M.R.*; SINNETT, P.M.; BAN, Y; AHADIZADEH, E.N.; Univ. of Oklahoma; Univ. of Oklahoma; Univ. of Oklahoma; Univ. of Oklahoma markham@ou.edu Electric fish generate brief electric organ discharges (EODs) for electrolocation […]
