(CNN) A walrus attacked and sunk a Russian Navy landing boat in the Arctic Ocean last week, with no one hurt in the incident.
According to the Russian Ministry of Defense, the female animal was protecting its calves when it targeted the craft carrying researchers to the shore of Cape Geller in the Arctic.
Those on board were members of a joint expedition by the Northern Fleet -- Russia's naval fleet in the Arctic -- and the Russian Geographical Society (RGO).
