Gray Whale

The Gray Whale is one of the most fascinating and impressive marine animals. It is a symbol of the oceanic garden. With a length of up to 15 meters and a weight that can reach 35 tons, these aquatic mammals are also known as Eschrichtius robustus. In this article, we will explore the main aspects of the Gray Whale, such as its habitat, behavior, adaptations, diet, and conservation.

The natural habitat of Gray Whales stretches along the west coast of North America, from the Chukotka Sea in Russia to Baja California, Mexico. These mammals are found primarily in the cold and shallow waters of the Pacific Ocean, although they can be found in some areas of the North Atlantic Ocean. Their annual journey includes an impressive migration, in which they cover one of the longest distances within and between their breeding and feeding grounds.

Because Gray Whales feed on clams, crustaceans, and marine worms, they are adapted to extract their food from the sediments on the ocean floor. The layer of blubber on their backs is particularly thick and heavy, allowing them to lie on the ocean floor and repeatedly roll in a behavior called "rootelling" to free their food. This unique adaptation enables them to obtain as much food as possible.

The behavior of Gray Whales is also impressive. They are social animals and live in small groups called pods, which consist mainly of adult females and their calves. Males join these seasonal groups only during the breeding season. Gray Whales are also known for their distinct songs, which are used for communication among group members.

Conservation of Gray Whales has become a major concern in recent decades. In the 19th century, these impressive creatures were on the brink of extinction due to intensified hunting. However, thanks to conservation efforts, the population of Gray Whales has gradually started to increase. Currently, they are protected by laws and international treaties that prohibit commercial hunting.

One of the biggest threats to Gray Whales today is pollution and climate change. Marine debris, such as plastic, as well as rising water temperatures, negatively affect the habitat of these animals and the food they consume. In addition, collisions with ships and accidental fishing remain a serious problem. Therefore, continued conservation and protection efforts for Gray Whales are essential to ensure their continued survival.

In conclusion, the Gray Whale is one of the most remarkable marine mammals. Their vast habitat, social behavior, unique adaptations, and impressive migration demonstrate that these animals are truly wonderful. However, their conservation is crucial to protect these magnificent creatures and ensure that future generations can admire and study them.










This species is endangered, so it has been protected by law since 1946. A current population of 15,000-22,000 is estimated.

For most of the Year , adults lead a relatively solitary life(or in small groups of 3-15 individuals), feeding in the frozen ocean (Arctic).

Every year, in February, they leave the cold waters and migrate through the Pacific Ocean near the western coasts of North America (Alaska, Canada, USA), traveling a distance of 16,000 km in about 3-4 months , to reach during the summer in the warm waters near Mexico – reg. Baja (lagoon "San Ignatio" - currently a nature reserve) for the breeding season.

During migrations and in warm waters, these whales do not feed, or consume very little food. At the end of the breeding season, the whales migrate again, along the same route, back to the Arctic Ocean for feeding season.The normal movement speed (migration speed) is 3-10km/hour. In case of danger they can advance by 16-18km / hour. The swimming speed during feeding is 1.6-4km/hour.

Feeding The Gray Whale

The gray whale feeds by filtering water.

It usually dives to the bottom of the sea, in not very deep areas, takes huge sips of the shore and filters with short fanons worms, shrimp, starfish, fish and other small creatures.

Features Of The Gray Whale

It has a long, thin head and quite small compared to the size of the body. The vertebrae of the neck are separated, and at the gatlej it has 2-4 creases characteristic of this species. It shows some formations called phanons, two rows on both sides of the upper jaw.

They have extensions that allow them to feed on plankton. They function as a brush that retains only the components of plankton from the water introduced into the mouth.

This whale reaches 13-15 m in length and weighs 14-35 tons. Its color is gray with white spots, the skin is encrusted with shells, whale lice and other outgrowths. On the back, the dorsal fin is replaced by a series of 8-9 bumps, and the tail has jagged edges.

It makes sounds like grunts, groans, wails or clamped claps. He leaps, standing upright in the water, with his head far out, to observe other whales, other landmarks or to check water currents for Migration.

The gray whale weighs about 30-35 tons(only the tongue weighs 1300 kg.

Breeding Gray Whale

These whales are used to swimming in pairs, migrating in groups of up to 10 specimens, in the northern regions to the Arctic (where krill is abundant) to feed in summer and in the southern regions to the lagoons to rest and make chicks, in autumn and winter.

At periods of two or three years, they give birth to live cubs, which they feed on milk. The newly born cub is helped by other whales in the group to reach the surface of the water to breathe.

The mother whale produces 250-300 liters of fatty milk daily, which is consumed by the chick and helps it grow very quickly. In the spring they return to higher altitudes, along with the infant chicks. Migrations are very long, gray whales travel distances of up to 20 000 km per year.

Longevity: 50-60 years. Enemies: killer whales (orcas) ,large sharks and whale hunters(Siberian Eskimos).
