Ecology of Ocythoe tuberculata
| Main Ref. | Cardoso, F. and C. Paredes, 1998 |
|---|---|
| Remarks | Female Ocythoe sp. typically occupy near-surface waters, having been encountered in the upper 10 m and captured in plankton hauls and on hook and line. While male Ocythoe sp. have been collected in pelagic tows at the sea surface, they are not restricted to surface waters, having been collected in closing nets at 100 to 200 m. Species are reported to feed on pteropod and heteropod mollusks, sardines, and crustaceans (Ref. 96968). |
