The whale's diet preferences has been determined from stomach analyses, direct observation of feeding behavior, and analyzing fecal matter collected near them, which appears as a dilute brown cloud. It's likely that some whales' diets depend on food availability. The whale uses its large tongue to force water out through the baleen plates which act as a sieve, and leave the prey trapped in the hairy fringes of the plates. It swims in small pods of 3-5 whales but larger groups may form at rich feeding grounds. Sei Whale. A marked The Sei Whale is a migratory species and is a fast swimmer that can reach speeds of 25 km/hr (Jefferson et al. Hirako S, Suzuki M, Kim H, Iizuka I, Matsumoto A, Wada N, Okabe M, Takenoya F, Yasunaga G, Yamanaka S, Miyazaki A, Shioda S. Hepatic lipid accumulation is ameliorated in obese KK mice by dietary sei whale … FOOD OF SEI WHALE TAKEN BY JAPANESE WHALING EXPEDITIONS IN THE ANTARCTIC SEASON 1967/68 AKITO KAWAMURA INTRODUCTION The comprehensive study on the food of baleen whales caught in the Antarctic by ... chaudii, and Drepanopus pectinatus were added to the diet list of baleen whales in the Antarctic.

They can dive 5 to 20 minutes to feed on plankton (including copepods and krill), small schooling fish, and cephalopods (including squid) by both gulping and skimming. The Sei Whale is among the fastest of all cetaceans and can reach speeds of up to 50 kilometres per hour (31 miles per hour) over short distances. Primary Diet fish The sei It is thickset and has small paddlelike flippers and a series of rounded humps on its back. Right whales are skimmers; bowheads and sei whales are skimmers some of the time. In order to maintain a healthy diet, pandas must consume 26 to 84 pounds of bamboo every day. The Sei Whale is a migratory species and is a fast swimmer that can reach speeds of 25 km/hr (Jefferson et al. Small fish and squid can also pass through Sei Whales’ baleen plates and thus also contribute to their diet. The sei whale (Balaenoptera borealis) is a dark-gray, stream-lined baleen whale that is found worldwide except in polar waters. Endangered Species.

The third largest whale species after blue whales and fin whales, sei whales are one of the most poorly understood of all baleen whales. Females typically give birth to one calf. 1999), summer distributions on the feeding grounds exhibit dramatic year-to-year differences (Andrews 1916, Jonsgård and Darling 1977, Waring et al. The n-3 PUFA con-tent of the FO diet was the same as that in the WO diet. Haldane, writing in 1909, opined that the sei whale was the “most graceful of all whales, as itsproportions are so perfect.” Sleek and slender, the sei is in fact similar in shape and Whale oil (WO) contains n-3 polyunsaturated fatty acids (PUFAs), but the effects of whale oil intake on lipid metabolism have remained unclear.

The name "sei" comes from the Norwegian "seje", used to describe a type of fish which gathers Norway's coast around the same time as sei whales.

Bryde's whales can easily be confused with sei whales, though they are smaller and inhabit warmer waters. Diet Tucking into a variety of treats, fish, squid, krill, copepods and zooplankton are all part of their diets.
