Minke whales could, in some circumstances, be confused with Baird's beaked whales; when a good look is obtained, differences in dorsal-fin shape, head shape, and coloration make the 2 easily distinguishable. They usually come to the water's surface 3-4 times at intervals of 10 -20 seconds before making a deep dive for at least 20 minutes. While diving, they generally feed between depths of 2,500 and 4,000 feet on deep-sea and open-ocean species of fish (e.g., mackerel, sardines, and saury), as well as crustaceans, sea cucumbers, squid, and octopus.

Thus, data are insufficient to estimate population trends. The black coloration form is the newly described species that are smaller and have a more northerly distribution off Japan and in the North Pacific Ocean (e.g., Sea of Okhotsk). Although they face threats from entanglement in fishing gear, commercial whaling, marine debris ingestion, and human-caused noise, Baird’s beaked whales are not listed as endangered or threatened under the Endangered Species Act. They will move farther offshore during winter and spring when sea temperatures have decreased. IUCN Red List Data Deficient Baird's beaked whales are the largest beaked whales and can grow to just over 11 metres in length, with females just pipping the males as the larger sex. They also have a curved head with a bulbous forehead (known as a melon); a distinct, long, cylindrical beak; a curved mouth line; and a crescent-shaped blowhole. Because of the uncertainty regarding their migration patterns and variable distribution, the two stocks off the U.S. West Coast may overlap. The oldest recorded age is 84 years for a male Baird's beaked whale and 54 years for a female. Whales sleep differently to humans, with only half of their brain asleep, so that they remember to breathe, otherwise they would drown. The layers of growth of these teeth determine the age of the individual. Our work protects this species by: Reducing entanglement in commercial fishing gear. seismic airguns used for oil and gas exploration.

These whales are among the least studied and most mysterious of all cetacean families. Identification is further complicated by their relatively small body sizes, elusive and shy behavior, and inconspicuous blow. These mammals have a long body, which increases in girth toward the middle. Baird's beaked whales have a large, slender, long, robust body with a relatively small, rounded, triangular dorsal fin that is located about two-thirds of the way down their back.

Predation from killer whales may also be responsible for some of these scars. The Alaska Fisheries Science Center has also tracked location data from satellite tags deployed on Baird’s beaked whales in the Gulf of Alaska to monitor their movements and habitat use. Baird's beaked whales, however, are some of the most commonly sighted beaked whales because of their social behavior and large body size. All Baird’s beaked whales are protected under the MMPA.
