Walruses – From Baby to Adulthood

Baby walruses, also known as walrus calves, are adorable and fascinating creatures. They are born to female walruses, or cows, usually on the ice. Unlike some other mammals, a female walrus generally gives birth to only one calf at a time, although rare cases of twins have been reported. These newborns weigh approximately 45 to 75 kg (99-165 lb.) and are already equipped with their famous tusks, although they are not fully developed at this stage.

The tusks of baby walruses are not used aggressively like those of adult males. Instead, they are used for various purposes, such as helping them navigate through the ice or aiding in climbing out of the water onto the ice floes. These tusks, which are actually elongated canine teeth, will continue to grow throughout their lives, reaching impressive lengths of up to one meter (3.3 feet) in males.

Baby walruses rely on their mothers for nourishment and protection. The bond between a mother and her calf is strong, and she will care for and nurse the calf until it is able to fend for itself. Like other mammals, walrus milk provides essential nutrients for the calf’s growth and development.

As the baby walrus grows, it will learn important survival skills from its mother. It will observe her feeding on clams, mussels, and other marine invertebrates, and eventually, it will begin to mimic her behavior. This learning process is crucial for the calf’s independent survival in the harsh Arctic environment.

The life of a baby walrus can be challenging, as it faces various threats from predators, including polar bears and killer whales. However, the mother’s presence and protection significantly increase the calf’s chances of survival.

The journey from a baby walrus to a fully grown adult is a long one. Walruses, both males and females, can live up to around 40 years old. Throughout their lives, these magnificent creatures will go through many changes and experiences, including participating in the breeding season and defending their territories.

Baby walruses, or walrus calves, are born on the ice and are already equipped with their iconic tusks. They rely on their mothers for nourishment and protection, learning essential skills for survival. As they grow, they will face various challenges and threats in the Arctic environment. These incredible creatures can live up to around 40 years old, carrying scars from disputes with fellow walruses on their skin. Baby walruses are a testament to the resilience and wonder of the natural world.

What Is A Male Walrus Called?

A male walrus is called a bull. Bulls are the adult male walruses characterized by their large size and distinctive tusks. These tusks are long, curved, and protruding teeth that can grow up to three feet in length. The tusks serve various purposes for the male walrus, including aggressive behavior and territorial defense.

Here are some key points about male walruses:

– Bulls use their tusks aggressively to establish and maintain their territories. They will often engage in tusk-to-tusk combat with other males to establish dominance and secure their territory.

– During the mating season, bulls use their tusks to protect their harems of females, known as cows. They will fend off rival males and ensure their exclusive access to the females for mating.

– Male walruses are generally larger in size compared to females. They can reach lengths of up to 12-13 feet and weigh up to 2,000-3,000 pounds. Their large size and powerful tusks make them formidable creatures in their natural habitat.

– The tusks of male walruses are elongated canine teeth that continuously grow throughout their lives. These tusks are composed of dentin, a hard and dense material, and are used for various purposes beyond aggression and defense. They can be used for digging through ice, hauling themselves onto land, and even as tools for breaking breathing holes in ice.

– The tusks of male walruses are unique to each individual, similar to human fingerprints. These tusks can be used to determine the age, health, and even the social status of a walrus.

The male walrus, also known as a bull, is distinguished by its large size and prominent tusks. These tusks play a crucial role in aggressive behavior, territorial defense, and protecting their harems during the mating season.

What Is A Newborn Walrus Called?

A newborn walrus is commonly referred to as a calf. They are usually born on the ice, and it is typical for a female walrus to give birth to a single calf at a time. However, it is worth noting that the birth of twins in walruses is rare but has been reported. These calves weigh approximately 45 to 75 kg (99-165 lb.) at birth. Here are some key points about newborn walruses:

– Newborn walruses are called calves.
– They are typically born on the ice.
– Female walruses usually give birth to one calf at a time.
– Twins in walruses are rare but have been documented.
– The weight of a newborn walrus calf is approximately 45 to 75 kg (99-165 lb.).

What Are The 2 Species Of Walrus?

The two recognized species of walrus, scientifically known as Odobenus rosmarus, are the Atlantic walrus (Odobenus rosmarus rosmarus) and the Pacific walrus (Odobenus rosmarus divergens). These two subspecies have distinct geographical distributions and exhibit some slight physical variations.

Atlantic Walrus (Odobenus rosmarus rosmarus):
1. Geographical Distribution:
– Primarily found in the Atlantic Ocean, especially in the coastal areas of eastern Canada, Greenland, and the Arctic regions of Europe.
– Their range extends from northeastern Canada (including the Hudson Bay and Newfoundland) to Svalbard and the Barents Sea.

2. Physical Characteristics:
– Generally smaller in size compared to Pacific walruses.
– Tend to have shorter tusks, which can reach up to around 80 cm (31 in) in length.
– Have a more flattened snout.
– Display a light gray to brownish coloration, with some individuals exhibiting pinkish hues.

Pacific Walrus (Odobenus rosmarus divergens):
1. Geographical Distribution:
– Primarily found in the Pacific Ocean, particularly in the Bering Sea and the Chukchi Sea.
– Their range extends from Alaska (including the Bering Strait and the Gulf of Alaska) to the northern coasts of Russia.

2. Physical Characteristics:
– Generally larger in size compared to Atlantic walruses.
– Tend to have longer tusks, which can reach up to around 100 cm (39 in) in length.
– Have a more rounded snout.
– Display a darker brown to reddish-brown coloration.

It is important to note that while these two subspecies of walrus have distinct distributions and some physical differences, they still belong to the same species, Odobenus rosmarus. The classification into subspecies helps in understanding their ecological and evolutionary relationships.

How Long Does A Walrus Live?

The average lifespan of a walrus is around 40 years. This means that on average, they can live up to 40 years old. It’s important to note that this is just an average, and individual walruses may live longer or shorter lives depending on various factors.

One of the reasons why walruses have a relatively long lifespan is their ability to adapt and survive in their natural habitat. They are well-equipped to thrive in the harsh Arctic environment. Additionally, they have few natural predators once they reach adulthood, which helps contribute to their longer lifespan.

However, it’s worth mentioning that walruses do face certain challenges that can impact their lifespan. For instance, climate change and loss of sea ice can disrupt their habitat and food sources, affecting their overall health and survival. Additionally, they can also face threats from human activities such as hunting and pollution.

In terms of physical appearance, most adult walruses carry a vast map of scars on their skin. These scars are typically the result of disputes and conflicts that occur during the breeding season. Male walruses use their long tusks to establish dominance and compete for mates, resulting in these visible wounds.

Walruses have an average lifespan of around 40 years. They possess unique adaptations to survive in their Arctic habitat and face challenges such as climate change and human impacts. The scars on their skin are a testament to the intense competition during their breeding season.


Baby walruses, also known as calves, are born on the ice and are usually solitary offspring. While twins are rare, they have been reported. These adorable newborns weigh approximately 45 to 75 kg (99-165 lb.) and are cared for by their mothers. Male walruses, or bulls, use their tusks aggressively to maintain their territory and protect their harems of females, or cows, during mating season. The lifespan of a walrus can reach up to 40 years old, and they often carry scars on their skin, evidence of past disputes with fellow walruses. these fascinating creatures are a testament to the resilience and adaptability of marine life.
