“…Both are cold-water forms and appear clearly discontinuous in distribution. Differentiation is slight and examination of recent specimens suggests that distinguishing characteristics are not as clear as was once thought (Pike, 1953;Slipp and WVilke, 1953). When the full range of variation in arnuxi becomes known, it may prove to warrant no more than subspecific separation.…”

“…4 Squid was the most common, but mackerel, sardine, and flat fish were also prey for this species in the western North Pacific off northern Japan, and in the southern Sea of Okhotsk. [6][7][8] However, details of the feeding habits of Baird's beaked whales are still limited. 5 Balcomb summarized the prey listed in the literature: squids Gonatus sp., Onychoteuthis sp., Moroteuthis sp., skates Raja sp., rat-tails Coryphaenoides sp., rockfish Scorpaenidae, and octopi Octopus sp., Tremoctopus sp.…”

[6][7][8] However, details of the feeding habits of Baird's beaked whales are still limited. In this study, we recorded prey species and also analyzed the mass and abundance of prey items and determined prey size, feeding time, foraging depth, and prey selection for Baird's beaked whales in the H Ohizumi et al western North Pacific and the southern Sea of Okhotsk off Japan.…”

Feeding habits of Baird's beaked whale Berardius bairdii, in the western North Pacific and Sea of Okhotsk off Japan

We examined the stomach contents of 26 Baird's beaked whales caught off the coast of Japan by small‐type coastal whalers. The main prey for these whales was rat‐tails and hakes in the western North Pacific. Pollock and squids were also important food in the whales collected from the southern Sea of Okhotsk. The prey species found in the stomachs of the whales were almost identical to those caught in bottom‐trawl nets at depths greater than about 1000 m in the western North Pacific, which suggests that the Baird's beaked whale forages for prey at depths of about 1000 m or more. Baird's beaked whales in the western North Pacific migrate to waters of 1000–3000 m in depth, where demersal fish are abundant. This implies that Baird's beaked whales migrate to waters where demersal fish, especially rat‐tails and hakes, are abundant. Although there is limited information on the feeding habits of ziphiid whales, they are generally thought to prefer squid. The present data suggest that demersal fish are also important prey for ziphiid whales.
