Beluga whales are not considered dangerous to people. There are no well-documented cases of a wild beluga seriously hurting someone, and belugas eat fish, squid, and animals on the sea floor, not people. They are still large wild animals, weighing up to about 3,300 pounds, so close contact can injure someone by accident, and a few reports from aquariums show the risk is not zero.
Do belugas attack people?
In the wild, belugas have no reputation for attacking people. The best-known wild beluga that sought out humans was Hvaldimir, a lone male first seen in Norwegian waters in 2019. He wore a harness that fueled "Russian spy" stories, approached boats, and reportedly played fetch. He was described as tame. The danger was to him: boat strikes left visible scars, according to Mongabay.
Reports of trouble mostly come from aquariums, and they point in both directions:
- In 2009, a beluga named Mila at the Polar Land aquarium in Harbin, China, noticed a free diver whose legs had cramped. Mila took the diver's leg in her mouth and guided her to the surface, National Geographic reported.
- In November 2023, video from an aquarium in Yunnan, China, showed a beluga taking a woman's head in its mouth for a few seconds during an underwater photo shoot, then biting at her legs and skirt while she swam to the surface. The China Cetacean Alliance, an animal welfare group that released the footage in 2024, called the behavior aggressive. Tag24's report does not confirm any injuries.
Why the whale acted that way is unknown.
What could a beluga do to a person?
Size is the main issue. Adult belugas are roughly 10 to 18 feet (3 to 5.5 m) long and can weigh up to about 3,300 pounds (1,500 kg), about as much as a small car. A bump, a push, or a grab from an animal that heavy can bruise, knock someone under, or cause a drowning even if the whale means no harm.
Belugas have 32 to 40 small, peg-like teeth, which wear down heavily over a lifetime, according to NOAA Fisheries and the Alaska Department of Fish and Game. The teeth are built for grasping fish, not for tearing large animals. A bite could still bruise or break skin.
A popular claim says belugas can bite through thick Arctic ice. They can't. Belugas break through thin ice, up to roughly 4 inches (10 cm), with their heads to reach air, according to Animal Diversity Web.
If a beluga or any other marine mammal bites or scrapes you, wash the wound well and have a doctor look at it, because these wounds can become infected. Get medical help right away for heavy bleeding, a deep wound, a head injury, or any near-drowning.
Is it safe to swim with belugas?
Swimming with wild belugas is discouraged and often illegal:
- Canada. Fisheries and Oceans Canada lists swimming with a marine mammal as a form of disturbance, and fines for getting too close can reach $100,000. Sea North Tours in Churchill, Manitoba, says new federal rules ended its swim-with-belugas trips. Kayak and boat tours there continue.
- United States. NOAA Fisheries does not support or authorize swimming with, petting, or touching wild whales, dolphins, or seals. The Marine Mammal Protection Act also bans feeding and harassing them, with civil penalties up to $36,498.
Older advice that wild belugas can be safely swum with "under controlled conditions" no longer matches these rules.
Belugas in human care are trained, but they are not domesticated. Any in-water program carries some risk, as the Yunnan video shows.
What to do if a beluga approaches your boat
- Slow down, hold a steady course, and avoid sudden changes in speed or direction.
- Stay at least 300 feet (100 yards) away in U.S. waters and limit watching to 30 minutes, per NOAA. In most Canadian waters the minimum is 100 meters, or 200 meters if the whales are resting or have a calf. For St. Lawrence belugas the minimum is 400 meters.
- Do not feed or touch the animals. NOAA says fed marine mammals lose their wariness of people and boats and can turn aggressive, which raises the risk of boat strikes.
- Watch the propeller. Sea North Tours notes that some belugas swim close behind boats to enjoy the propeller bubbles, and propellers can injure or kill them.
Can beluga sounds hurt you?
Belugas make whistles, calls, and echolocation clicks, and they are loud. Beluga sounds are not known to injure people, though. The noise problem runs the other way. Ship and industrial noise is one of the threats NOAA lists for belugas.
Who is really at risk?
People are far more dangerous to belugas than the reverse. NOAA lists climate change, contaminants, disease, ocean noise, harassment, and prey shortages among the threats. In Alaska's Cook Inlet, where numbers fell from about 1,300 in 1979 to roughly 300, the population is listed as endangered. Wild belugas' natural enemies are killer whales and polar bears, not people.
