occurred in 52% of the samples, and Carinaria cithara was found in 50% of samples.
Of the six most common prey items, Carinaria cithara had the highest percent sample volume, 43.8% of total sample volume.
An initial study of pelagic dive behavior of this species (Polovina et al., 2003) indicates that they regularly dive down to depths of 100 m and may also forage at those depths, which may account for the high frequency of occurrence and high total percent volume of the heteropod Carinaria cithara.
