Most walruses are hunted at sea. And as the Arctic opens up to more shipping, tourism, industry and noise, the Atlantic walruses are at greater threat of disturbance, and therefore stampedes.

[4] They are not particularly deep divers compared to other pinnipeds; the deepest dives in a study of Atlantic walrus near Svalbard were only 3117m (102ft)[72] but a more recent study recorded dives exceeding 500m (1640ft) in Smith Sound, between NW Greenland and Arctic Canada - in general peak dive depth can be expected to depend on prey distribution and seabed depth. Something as simple as accidentally scratching your eye with a sharp fingernail can cause an eye injury. 4. During their mass gatherings, stampedes can occur as easily spooked walruses attempt to reach the water.
