Walrues

Walruses are large, social marine mammals, instantly recognizable by their distinctive ivory tusks and prominent, stiff whiskers. Found inhabiting the frigid waters of the Arctic and sub-Arctic, these blubbery giants are a, distinct species known as Odobenus rosmarus, which translates to "tooth-walking sea horse". They play a crucial role in their ecosystem and are highly adapted to a life that bridges the icy surface and the deep sea floor. With two main subspecies—the Atlantic and Pacific walruses—they are a vital part of the Arctic's biodiversity.
Their most defining features, the long tusks, are actually elongated canine teeth that continue to grow throughout their lives. These impressive tusks, which can reach up to three feet in length, are used for a variety of survival-related tasks, including hauling their massive bodies out of the water onto sea ice, creating breathing holes, and demonstrating social dominance. Both males and females possess these tusks, which also offer protection against natural predators such as polar bears and orcas.
Walruses are specialized foragers, feeding primarily on benthic invertebrates found on the seabed, such as clams, mussels, and worms. They possess roughly 400 to 700 highly sensitive whiskers, or vibrissae, which allow them to locate food in the dark, murky waters of the ocean floor. Once they identify their prey, they use their mouths to create a vacuum, extracting the meat from the shells, often consuming thousands of clams in a single feeding session.
These mammals are exceptionally social creatures, often gathering in large, dense herds known as "haul-outs," which can include hundreds or even thousands of individuals on land or ice. They are a noisy group, communicating through a variety of grunts, bellows, and clicks. During breeding season, males become more aggressive, fighting for territory, while the herds often divide based on sex for the rest of the year.
Despite their resilience, walruses face significant threats, primarily from climate change and the rapid, ongoing loss of sea ice. As sea ice decreases, they are forced to use land-based haul-outs, which can limit their access to feeding areas and make them more vulnerable to starvation and disturbances. The species is currently listed as vulnerable to extinction, making conservation efforts in the Arctic crucial for their survival.
