Abstract

Oceanic ctenophores are widespread predators on pelagic zooplankton. This data describes the daytime and nighttime gut contents of a ubiquitous oceanic ctenophore, Ocyropsis spp. as a component for evaluating trophic impact of this and other oceanic ctenophores in planktonic communities. In situ imaging of Ocyropsis spp. were made via blue-water (daytime) and black-water (nightime) SCUBA diving from a small boat along the western edge of the Gulf Stream, 5 to 8 km off the coast of West Palm Beac...

In situ images of Ocyropsis guts were taken by SCUBA divers in order to quantify gut contents of live animals in situ. These images were taken at various depths within the upper 15 meters of the water column at various times of day, over the course of multiple dives.

The data table differentiates day vs night time collection. High-resolution images taken using a Nikon 750 DLSR camera allowed estimation of gut fullness. ImageJ software aided the standardization of the estimations made from these image files.
