Their distribution in U. They prefer waters less than feet deep. The distribution of this species varies with the seasons. Most white-beaked dolphins move south and farther offshore during the winter months.
They then return north and closer to shore once the ice recedes during the warmer summer months. The estimated lifespan of white-beaked dolphins is unknown.
They reach sexual maturity when they are seven to 12 years old. Females are pregnant for about 11 months and give birth to a single calf, usually between May and September. Calves are about 3. One of the main threats to white-beaked dolphins is becoming entangled or captured in commercial fishing gear such as gillnets, cod traps, and trawl nets. These interactions can cause dolphins to be injured or killed. White-beaked dolphins are sometimes targeted and hunted for meat and oil in waters off Canada Labrador and Newfoundland , Greenland, Iceland, and Norway.
White-beaked dolphins rely on sound to communicate and echolocate. Increasing evidence suggests that exposure to intense underwater sound in some settings may cause some dolphins to strand and ultimately die.
If loud enough, noise can cause temporary or permanent hearing loss. NOAA Fisheries is committed to the protection of white-beaked dolphins. Targeted management actions taken to secure protections for these dolphins include:. Our research projects have discovered new aspects of white-beaked dolphin biology, behavior, and ecology and helped us better understand the challenges that all white-beaked dolphins face.
Our work includes:. Dolphins fed by humans lose their natural wariness and learn to associate people with food, causing them to beg for handouts and take bait and catch directly from fishing gear. This puts them at risk from vessel strikes and becoming entangled in or ingesting fishing gear.
Dolphins may teach these behaviors to their young, thereby putting them at risk. More on protecting wild dolphins and admiring them from a distance. Be responsible when viewing marine life in the wild. Observe all dolphins and porpoises from a safe distance of at least 50 yards and limit your time spent observing to 30 minutes or less. Learn more about our marine life viewing guidelines. Report a sick, injured, entangled, stranded, or dead animal to make sure professional responders and scientists know about it and can take appropriate action.
Numerous organizations around the country are trained and ready to respond. Never approach or try to save an injured or entangled animal yourself—it can be dangerous to both the animal and you.
Learn who you should contact when you encounter a stranded or injured marine animal. This hotline is available 24 hours a day, 7 days a week for anyone in the United States.
We work with volunteer networks in all coastal states to respond to marine mammal strandings including all dolphins and porpoises. When stranded animals are found dead, our scientists work to understand and investigate the cause of death. How fast do white-beaked dolphins swim?

Off Newfoundland, Canada, white-beaked dolphins have been reported to eat cod and in the Hebrides, NW Scotland, they are often associated with mackerel shoals. Other prey items include squid, octopus, cod, herring, capelin and sometimes benthic crustaceans. White-beaked dolphins have been observed to use fish herding techniques, including; small groups of dolphins converging in an area, gathering the fish in the process; using echelon formation, moving in the direction of a small group of dolphins, to trap the fish; and rushing to the surface in a group lined up abreast, while other dolphins converge on them to trap the fish.
These techniques of herding seem to panic the fish, which scatter, and are picked off by the dolphins. Herding fish in this manner is highly cooperative, requiring synchronisation of dives, surface rushes and re-grouping.
Individuals may communicate with others in the group as well as corral fish using whistles, breaches, tail slaps and somersaults. The white-beaked dolphin has been reported in large schools, up to several hundred individuals in the eastern Atlantic, but mostly occurs in smaller schools in the western Atlantic. Around the UK, most sightings are of groups of less than 10 animals, although larger pods of up to have been recorded. Terms Photo Credits Sitemap. Webdesign by Hotscot.
