Grey whales are known for their epic migrations.

Each year, these magnificent creatures travel up to 12,000 miles between their feeding grounds in the Arctic and their breeding grounds in the warm waters of Baja California.

Adult grey whales can reach lengths of up to 50 feet.

These gentle giants are among the largest mammals on Earth, weighing up to 40 tons.

Grey whales have baleen plates instead of teeth.

They use these comb-like structures to filter small crustaceans and other planktonic prey from the water.

The diet of grey whales mainly consists of amphipods and mysid shrimp.

These tiny marine organisms provide the necessary energy for the whales’ long and strenuous migrations.

Grey whales are bottom feeders.

They often stir up sediment on the ocean floor and then filter out the prey from the muddy water.

Grey whales have a unique feeding behavior called “lunge feeding”.

They can engulf large amounts of water and prey in a single motion, expanding their throat pouch to accommodate the catch.

Grey whales are highly social animals.

They often travel in small groups, known as pods, and communicate with each other through various vocalizations.

The population of grey whales is divided into two distinct groups.

The Eastern North Pacific population migrates between Alaska and Mexico, while the Western North Pacific population migrates between Russia and Korea.

Grey whales have a unique breeding behavior called “mating groups”.

Multiple males will court a single female, and she will choose a mate based on their displays of strength and agility.

Female grey whales have the longest known gestation period of any mammal.

They carry their calves for approximately 12-13 months before giving birth in the warmer waters of Baja California.

Grey whale calves are born weighing around 1,500 pounds.

Despite their size, they are incredibly active and can swim alongside their mothers shortly after birth.

Grey whales have a highly developed sense of smell.

They use it to navigate, locate feeding areas, and communicate with other members of their pod.

The grey whale’s scientific name is Eschrichtius robustus.

This name honors Danish zoologist Daniel Frederik Eschricht and reflects the robust nature of these majestic creatures.

Grey whales have a round, knobby head with distinct throat grooves.

These grooves allow the throat to expand and accommodate large amounts of water during feeding.

Grey whales are known for their distinctive mottled gray color.

This coloration helps them blend in with the rocky shores and kelp forests they frequent.

Grey whales are highly migratory, but they do not migrate in a straight line.

They navigate using a combination of celestial cues, magnetic fields, and coastal landmarks.

Grey whales have a lifespan of approximately 50-70 years.

However, some individuals have been known to live beyond 80 years.

Grey whales have few natural predators.

Orcas, also known as killer whales, are their main predators, but they rarely prey on adult grey whales.

Grey whales play a vital role in the ecosystems they inhabit.

By stirring up sediment and redistributing nutrients, they contribute to the overall health and diversity of the marine environment.
