Caprella suprapiscis sp. nov. (Crustacea: Amphipoda: Caprellidae) from the Pacific coast of Mexico.
A new species of caprellid, Caprella suprapiscis sp. nov., is described based on several specimens collected from Bahía Chamela, Jalisco, Mexico.

The species is distinguished by head with a short dorsal projection, eyes distinctive, body slender and smooth, peduncu...
متن کاملSAR Data Help Improving the Monitoring of Intertidal Flats on the German North Sea Coast
Synthetic Aperture Radar (SAR) data have been included into an existing monitoring system to complement the classification of sediments, macrophytes, and mussels in the German Wadden Sea. Whereas the use of satellite-borne optical sensors in northern latitudes is strongly limited by clouds and haze, SAR data allow earth observation that is independent of cloud coverage and daytime. SAR data acq...

متن کاملIs the Japanese skeleton shrimp Caprella mutica a filter feeder? I. Head morphology and kinematics
An active filter feeding organism strains suspended matter from the surrounding water using a sieving structure. Small marine filter feeders however, have to cope with the physical problems of the high viscosity as indicated by the low Reynolds number. In a highly viscous regime, organisms' appendages are surrounded by a thick boundary layer, which makes movement and filter feeding difficult. I...
