Walrus
Odobenus rosmarus
The walrus (Odobenus rosmarus) is a large Arctic pinniped strongly tied to shallow continental‑shelf seas and seasonal sea ice. It forages mainly on the seafloor, using sensitive whiskers (vibrissae) to locate clams and other benthic invertebrates, which it extracts by suction.

Walrus ivory and hides were essential to Arctic Indigenous peoples for millennia, used for tools, boats, and food. Their declining numbers due to sea ice loss are a direct indicator of climate change. Tusks serve as both social signals and ice anchors.
