Walrus
Odobenus rosmarusAlso known as Pacific Walrus, Atlantic Walrus, Morse
Walruses are massive Arctic marine mammals easily recognized by their long ivory tusks, sensitive facial whiskers, and thick wrinkled hide. They spend much of their lives on pack ice and shallow coastal haul-outs, using their stiff vibrissae to feel along the dark seafloor for benthic invertebrates. Highly social creatures, thousands of individuals often crowd together on land or ice, communicating through loud bellows, grunts, and bell-like whistling sounds.

Interaction riskHigh
- Low
- Moderate
- High
- Very high
- Why interaction risk is high
- Massive size and sharp tusks present severe risk; maintain at least 100 meters distance on land and sea.
- Why it is dangerous
- Weighing up to two tons, walruses can crush humans and deliver fatal thrusts with their long ivory tusks.
- How to recognize a risky encounter
- Enormous size with reddish-brown wrinkled skin, thick facial whiskers, and long downward ivory tusks.
- What to do
- Stay back at least 100 meters and back away slowly if a haul-out shows signs of agitation.
- What to notice
- Densely packed herds resting on coastal gravel beaches or drifting sea ice floes.
- Support conservation
- Use binoculars or telephoto lenses to observe without causing costly energetic stress or stampedes.
Responsible observation
- Observe from Afar: Maintain at least 100 meters distance to avoid causing panic stampedes on haul-outs.
- Minimize Noise: Avoid engine throttling or loud sounds near resting groups along coastal shores.
- Watch Water Paths: Give swimming individuals ample room to surface and navigate freely.
