The sei whale population was decimated by commercial whaling in the 1800s and early 1900s. They prefer temperate waters in the mid-latitudes, and can be found in the Atlantic, Indian, and Pacific Oceans. Underwater noise may threaten sei whales by interrupting their normal behavior and driving them away from areas important to their survival. Sei whales occur in subtropical, temperate, and subpolar waters around the world. Washington, DC 20037.

Some strandings can serve as indicators of ocean health, giving insight into larger environmental issues that can have implications for human health and welfare. Sei whales are dark, sleek baleen whales that are found offshore in subtropical, temperate, and subpolar waters worldwide.

There are around 80,000 Sei Whales in the wild today. Some whales are barely recovering from the whaling industry, while others have increasing numbers. This is only little more than 20 percent of the original population estimate of 42,000 for this area. 20294 to Robert DiGiovanni Jr. for Vessel and Aerial Surveys of Blue, Fin, North Atlantic Right, Sei, and Sperm Whales, Biological Opinion on the Replacement of the Unalaska Marine Center Dock Positions III and IV and associated Proposed Issuance of an Incidental Harassment Authorization in Dutch Harbor, Unalaska, Alaska, Alaska Endangered Species and Critical Habitat Mapper Web Application, Passive Acoustics Research Group News & Media, Acoustic Studies Sound Board of Marine Mammals in Alaska, NATIONAL OCEANIC AND ATMOSPHERIC ADMINISTRATION, Report a Stranded or Injured Marine Animal, Learn more about our conservation efforts, NOAA Office of Law Enforcement field office, Initiation of 5-Year Reviews for the Endangered Fin Whale, Endangered Gray Whale Western North Pacific Distinct Population Segment, and Endangered Sei, Notice of Initiation of 5-Year Review/Request for Information, Notice of Availability of Draft Recovery Plan, Incidental Take Authorization: Ørsted Wind Power North America, LLC Site Characterization Survey off New York to Massachusetts, Amendment to Biological Opinion (pdf, 19 pages), Incidental Take Authorization: Lamont-Doherty Earth Observatory Marine Geophysical Survey in the Aleutian Islands, Finding of No Significant Impact (pdf, 14 pages), Incidental Take Authorization: Equinor Wind, LLC Marine Site Characterization Surveys off of Massachusetts, Rhode Island, Connecticut, New York and, Incidental Take Authorization: Mayflower Wind Energy, LLC Marine Site Characterization Surveys off of Massachusetts, NOAA’s Alaska Fisheries Science Center Marine Mammal Laboratory. Like other great whales, they prefer to spend the summer feeding in cooler waters before migrating to warmer waters to breed and give birth to their calves. BANDON, Ore. (AP) — An endangered species of whale that became stranded on a southern Oregon beach died over the weekend, officials said.

At the water's surface, sei whales can be sighted by a columnar or bushy blow that is about 10 to 13 feet in height. Sei whales of course also have natural predators such as orcas, swordfish, (Harrison) and sharks (“Sei Whale Balaenoptera borealis.”), but swimming at fast speeds (“Sei whale [Balaenoptera borealis].”) is an adaptation to avoid those predators.

Range: Sei Whales have a largely unknown geographic distribution, as their wintering grounds have not yet been identified. Often found with pollack in Norway, the name \"sei\" comes from the Norwegian word for pollack, \"seje.\" Acoustics is the science of how sound is transmitted. Skimming the water for food while swimming, their short ventral pleats and bristle-packed baleen help them to collect as much delicious food as possible.
