How does a walruses move?
Walruses can move surprisingly fast on land, matching the running speed of a human being. They run on all fours like a dog. While swimming, walruses become graceful and use full-body movements to glide through the water. On average, walruses swim about 7 kph (4 mph) but can speed up to 35 kph (22 mph) if necessary.
How do walruses move on ice?
Their flippers are hairless. The skin on them is thick and rough, providing traction on land and ice. ... Walruses use their long ivory tusks to haul their heavy bodies up onto the ice, to forage for food, and to defend against predators. The main role of the tusks, however, is a social one.
What do walruses use their large tusks for?
Both male and female walruses have large tusks
They use these tusks to help them haul themselves out of the water and onto sea ice. Their tusks are also used for fighting with other walruses, and defence against predators.
Are walruses muscular?
The walrus has a muscular body which it uses to manoeuvre through the water. Its four flippers help with steering and it is also able to turn its rear flippers forwards in order to help it move on land. The snout of the walrus is covered in sensitive bristly whiskers called mystacial vibrissae.
What are walrus whiskers?
The whiskers, also known as vibrissae, are attached to muscles and are supplied with blood and nerves, which makes them highly sensitive. Walruses use these sensitive whiskers to locate prey. They hunt with their noses to the sea floor, squirting water out of their nostrils to stir up burrowing prey.
What are walrus whiskers made of?
They Find Food With Their Vibrissae
Though often mistaken for a mustache, the whiskers on a walrus are not hair, but incredibly sensitive vibrissae. Walruses have between 400 and 700 of these tactile organs lined up in 13 to 15 rows around the nose.
How are walruses adapted to their environment?
To keep warm in the chilly arctic waters, walruses have a thick layer of blubber that can be up to 4 inches thick. To keep their vital organs and core warm, blood will be shunted off from the surface of their skin, making them appear white and pasty.
Are there walruses without tusks?
The roughly 10-foot-long (3 meters) creature didn't have tusks as walruses do today, but instead sported "moderate-sized upper canines," that measured 3.4 inches (86.3 millimeters) long, the researchers wrote in the study. ...
Do walruses sweat?
Cetacea (whales & dolphins) & Sirenia (manatees & dugongs) don't have sweat glands. Pinnipedia (seals, sea-lions & walruses), Lutrinae (otters), Castoridae (beavers), the kinkajou (honey bear) & Homo all have both extensive sweat glands & squalene-rich sebum for waterproofing.
Why are walrus eyes red?
When walruses enter cold water they become paler still, as blood flow to the skin is reduced. Conversely, when these animals are warm, the skin becomes flushed with blood and they acquire a rosy red "sunburned" colour.
How much is a walrus tooth worth?
Tusks also come in handy for scraping up food or helping to pull the animals up onto land or ice. True ivory walrus tusks can be hard to come by; and as of July 2011, those that are legally sold can be worth as little as $100 or in some forms as much as $50,000.
Can walrus tusks grow back?
The tusks grow continually, like the incisors of rodents, elephants, and a few other mammals. Their growth is cumulative; new increments are added at the proximal end of the tusk, resulting in a continual increase in length as well as in mass with increasing age.
How fast can a walrus swim?
Walrus travel primarily by swimming. They spend about two-thirds of their lives in the water. By using their hind flippers like a propeller, they can swim at an aver- age speed of 4.3 miles per hour (mph) and as fast as 21.7 mph. Like all good swim- mers, walrus know that they need to rest.
Why do walrus eyes pop out?
The extraocular muscles of the walrus are well-developed. This and its lack of orbital roof allow it to protrude its eyes and see in both a frontal and dorsal direction.
How can you tell if a walrus is male or female?
To distinguish between male and female Pacific walruses, they measured the length and height of the jawbone, the minimum jawbone depth (from about the middle point of the jaw to the back), and jaw thickness.
