Fun Facts

Fun Facts

  • The tusks of walruses are their canines, which can grow up to 1 m long. They plunge these large teeth into ice to make breathing holes, or to pull their bulky bodies out of the water. Male walruses also use them aggressively to defend their territory and protect their harems.

  • To protect themselves from the cold, walruses have thick layers of blubber to conserve heat. The blood vessels near the skin can also be constricted to reduce blood flow and thus minimise heat loss.

Threats & Conservation

IUCN Red List: Data Deficient
IUCN Red List: Data Deficient
CITES: Appendix III
CITES: Appendix III

Walruses require sea ice for breeding and for reaching offshore feeding sites. As global warming reduces sea ice cover and alters its spatial and temporal patterns, walruses have come under threat. These animals are also highly sensitive to human disturbance. Activities such as trawl fishing can cause them to abandon sites.
