Are there any records of dwarf sperm whales feeding on the surface? I recently saw them swimming in circles just outside a feeding aggregation of wedge-tailed shearwaters, strongly suggesting that they were also catching something (appr. 27.81N 141.78E). I looked through the few books I have and everything I could find on Kogia in Google Scholar, but didn't find any mention of surface feeding. Looks like everybody just assumes them to be obligatory deep divers, even though the list of known prey species on OBIS-SEAMAP page includes some squid species (i. e. Ilex argentinus) that are caught on surface by squid fisheries.
