Live Stranded Sowerby’s Beaked Whale Near Île Verte A Sowerby's beaked whale came too close to the shore of Ile Verte. When stranded animals are found dead, our scientists work to understand and investigate the cause of death. Although the cause often remains unknown, scientists can sometimes identify strandings due to disease, harmful algal blooms, vessel strikes, fishing gear entanglements, pollution exposure, and underwater noise. The results of this research are used to inform management decisions and enhance protection efforts for this species. Learn more about our marine life viewing guidelines >. Therefore, much of the available characterization for beaked whales is to the genus level only, and there is relatively little information about most individual species. Reducing interactions with commercial and recreational fishing gear. Due to the rarity of sightings at sea, there is little information on the abundance of Sowerby’s beaked whales worldwide.

Sowerby's beaked whales prefer the deep, cold temperate and subarctic waters off the continental shelf edge of the North Atlantic Ocean but have also been reported near the ice pack. Our acoustic research also assesses the degree to which human-caused activities are changing the underwater soundscape, how these changes may potentially impact marine animals, and what measures can be taken to mitigate these potential impacts. Sowerby’s beaked whales also may be susceptible to at least occasional entanglement in longline gear. Sowerby's beaked whales have a small- to medium-sized body with a very long, slender beak relative to other beaked whales, as well as a bulge on the forehead area. NOAA Fisheries is investigating all aspects of acoustic communication and hearing in marine animals, as well as the effects of sound on beaked whale behavior and hearing. Ben First described by English naturalist James Sowerby in 1804, Sowerby's beaked whales are reclusive creatures that stay away from ships and are rarely … This weekend we had two separate incidents involving Sowerby’s beaked whales becoming live stranded in England.
