Odobenus is ancient Greek for 'tooth-walker' and refers to the way walruses (Odobenus rosmarus) pull themselves up on the ice with their tusks, which are used to dig clams and mussels out of the seabed.
The 50,000-strong Atlantic population is stable but Pacific walruses, which have been hunted to depletion and allowed to recover several times, have probably reached saturation point. In the early 1980s, they began to appear leaner and increased their consumption of alternate foods such as fish (their preferred diet is mussels and clams). Natural mortality increased, birth rates decreased. There was just not enough food to go round and, added to an increase in subsistence catches by indigenous Arctic peoples, the Pacific walrus is on the verge of yet another decline.
