Do walruses travel in packs?
A group of walruses is called a herd. They gather by the hundreds to sunbathe on the ice. During mating season, walruses amass by the thousands. A herd is usually segregated by gender; females have their own herds, and males have their own herds.
Do walruses migrate?
MIGRATION: Pacific walruses winter in the central and south Bering Sea and summer in the Chukchi Sea. Adult females and their young are migratory, following the sea ice edge north in the summer, while males remain in the south and haul out onto rocky beaches when the ice melts.
Why do walruses haul out?
Walruses haul-out onto land primarily for birthing, moulting, nursing, and resting, meanwhile using sea-ice haul-out sites for foraging and predator avoidance. ... Haul-out frequency is at a maximum for walruses during the summer using terrestrial haul-out sites as sea ice sites are then further from foraging grounds.
Do walruses dive?
Despite their size and their ability to stay underwater for up to half an hour, walruses are not deep divers—they usually feed at depths of less than 300 feet.
How far does a walrus travel?
Some walruses migrate more than 3,000 km (1,863 miles) each year. Pacific walrus adult females and young walruses are more migratory than adult males.
How fast does a walrus move on land?
Walruses can move surprisingly fast on land, matching the running speed of a human being. On average, they'll swim at about 7km an hour, and can speed up to 35km per hour.
Do walruses hibernate?
A new study on the sleeping habits of walruses reveals that these flippered marine mammals are some of the world's most unusual snoozers, since they appear to sleep anywhere, but they may also break the world's record for continuously staying awake.
Do walruses live in the ocean?
Walruses live in Arctic and sub-Arctic regions of the world near the North Pole. They can be found in the Pacific Ocean, Atlantic Ocean, and Arctic Ocean.
What is a walrus life cycle?
Females begin breeding at 6-7 years of age and generally give birth every 2 years. Males are mature at 8-10 years of age, but generally cannot successfully compete against older, larger males for females until they are 15 years old. Walruses may live up to 40 years.
What are walrus haul outs?
Walruses spend most of their time on sea ice. They migrate with moving ice floes and need ice for rest between dives for food. ... As a result, thousands of walruses are swimming much farther distances to seek refuge on shore when no ice is available. On land, they congregate in large groups known as “haulouts.”
How far can walrus swim?
Walrus migrate with the moving ice floes, but never venture far from the coast as they feed in shallow waters. They can swim to a depth of around 100m to feed on molluscs and other invertebrates, but on average do not go much deeper than 20-30m.
Why do GREY seals haul out?
Seals spend a great deal of time at sea, hauling out onto land at certain times of year to give birth and suckle their pups (through the autumn in the eastern Atlantic), moult (spring) and to rest after periods of diving and feeding.
How fast can a walrus run?
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 intelligent is a walrus?
Walruses live up to around 40 years in the wild. ... Walruses are intelligent animals. Scientists are gathering evidence that the walrus is the most cognitively and socially sophisticated of all pinnipeds. The upper canine teeth of the walrus are known as morse or tusks.
What does the walrus have that keeps it warm?
During the winter, blubber can make up up to a third of a walrus's body mass. That keeps the walrus toasty warm as it slices through frigid waters. Blubber is just one way that marine mammals keep warm.
