What Do Grey Whales Eat
In the wild, grey whales can live up to 70 years old. They are filter feeders and eat a variety of small marine creatures including krill, copepods, amphipods, squid, and crabs. Their diet is relatively low in fat which helps them maintain their buoyancy.
Grey whales have been known to travel long distances in search of food. During their migration from Alaska to Mexico, they may travel over 10,000 miles!
What Does a Gray Whale Eat?
In the wild, grey whales are known to eat a variety of small fish, crustaceans, and mollusks. They have been known to also eat sand and sediment in order to help them digest their food properly. In captivity, however, their diet is much different.
Most captive grey whales are fed a diet of herring, capelin, and krill.
Where Do Grey Whales Live
If you’ve ever seen a whale in the wild, there’s a good chance it was a grey whale. These massive creatures are some of the most common whales in the world, and they can be found in nearly all oceans. Here’s what you need to know about where grey whales live.
Most grey whales spend their summers in the Arctic waters off Alaska and northern Canada. They travel to these cooler waters to feed on plankton and small fish. In the winter, they migrate south to breed in warm, shallow lagoons in Mexico and along the coasts of California and Oregon.
During their migration, grey whales can travel up to 12,000 miles round-trip! That’s one of the longest migrations of any mammal on Earth.
While grey whales used to be hunted for their oil and meat, they are now protected from hunting by international law.
However, they still face threats from pollution, entanglement in fishing gear, and ship strikes. Scientists estimate that there are only about 20-25 thousandgrey whales left in the wild today.
Do Grey Whales Eat Fish
Most people think of whales as filter feeders, straining huge amounts of ocean water for tiny krill and other crustaceans. But some species of whale are actually predators, and one of these is the grey whale.
The grey whale is a baleen whale, which means that instead of having teeth, it has long plates of keratin in its mouth that it uses to filter its food from the water.
Baleen whales are mostly vegetarian, but the grey whale is an exception – it feeds on bottom-dwelling marine creatures like crabs, squid, and yes, fish.
It’s thought that the grey whale evolved to become a predator because its main food source – small crustaceans – became scarce in areas where the whales lived. To survive, they had to adapt and start eating other things.
Interestingly, scientists have found that grey whales in different parts of the world have slightly different diets. For example, those living off the coast of California primarily eat amphipods (a type of shrimp), while those in the Bering Sea eat mainly codfish eggs. This just goes to show how adaptable these amazing creatures are!
What Do Whales Eat
Most people think of whales as giant, gentle creatures that live in the ocean and eat fish. But there are actually many different types of whales, and they don’t all eat the same thing. Some whales are filter feeders and eat tiny organisms called krill.
Others are toothed whales and hunt for fish, squid, and other marine animals.
Blue whales are the largest animals on Earth, weighing in at up to 200 tons! These massive mammals usually eat tiny shrimp-like creatures called krill.
They can consume up to 40 million krill each day – that’s about 12,000 pounds! Blue whales aren’t the only ones who feast on krill; humpback whales, fin whales, minke whales, and right whale also love this little creature.
Baleen whales are a type of filter feeder whale that has long plates of baleen instead of teeth.
Baleen is made from keratin (the same substance our fingernails and hair are made from) and hangs down from the roof of their mouths like a curtain. As they swim through swarms of tiny prey animals like krill or small fish, they open their mouths wide and take in huge mouthfuls of water. Then they push the water back out through their baleen plates – trapping their dinner inside!
Other baleen whale species include bowhead whale, grey whale , pygmy right whale , sei whale , Bryde’s whale , Omura’s whale , Eden’s whale .

What Eats Grey Whales
There are a variety of animals that feed on grey whales. These include orcas, sharks, and large baleen whales. The main predators of grey whales are humans and killer whales.
Orcas are the most common predators of grey whales. They attack in groups, using their size and strength to overpower their prey. Grey whale calves are especially vulnerable to Orca attacks, as they are not yet large enough to defend themselves effectively.
Killer whales will also target sick or injured grey whales, as they are easier to take down than healthy adults. Humans have hunted grey whales for centuries, primarily for their oil and meat. In recent years, however, the population has begun to rebound thanks to conservation efforts.
How Long Do Grey Whales Live
There are many different types of whales, and each type has a different lifespan. The average lifespan of a grey whale is around 70 years. However, there have been some reports of grey whales living to be over 100 years old.
There are several factors that can affect the lifespan of a grey whale, including their diet, environment, and predation. Grey whales are one of the longest-lived mammal species on Earth.
Where Do Gray Whales Migrate
Every year, gray whales embark on one of the longest migrations of any mammal. They travel between their breeding grounds in the warm waters off Mexico and their feeding grounds in the Arctic. Along the way, they pass through some of the busiest shipping lanes in the world.
Why do they make this journey? For food, of course! In the spring and summer, gray whales feast on tiny crustaceans called amphipods that live near the seafloor.
These little creatures are packed with nutrients and fat, which help the whales build up their energy reserves for their long journey south.
The trip from Arctic to Mexico can take up to three months, and gray whales must travel more than 10,000 miles round-trip! That’s a lot of swimming!
Thankfully, they’re built for it – gray whales have large flukes (tails) that help them swim powerfully through the water. They also have unique pleats on their underside that allow them to store oxygen so they can hold their breath for long periods of time while swimming.
During their migration south, gray whales will often stop to rest and socialize in groups called pods.
They may even mate during these stops. Once they reach Mexico, it’s time to give birth and care for their young calves before beginning the long journey back north again next year.
What Do Humpback Whales Eat
Humpback whales are filter feeders, which means that they strain small prey from the water using their baleen plates. Their diet consists mostly of krill and small fish, which they eat by gulping large mouthfuls of water and then pushing the water out through their baleen plates, trapping the prey in their mouths. Humpbacks sometimes work together to corral fish into tight groups before feeding on them.
Do Grey Whales Eat Krill
Do Grey Whales Eat Krill?
Yes, grey whales do eat krill. In fact, krill makes up a large part of their diet.
Krill are small crustaceans that live in the ocean. They are an important food source for many animals, including whales.

What are Gray Whales Favorite Food?
Gray whales are baleen whales, which means they have bristles instead of teeth. These bristles are used to filter their food out of the water. Gray whales primarily eat amphipods, small shrimp-like crustaceans that live in the ocean floor.
Gray whales will also consume other small marine animals, including squid, fish eggs, and crab larvae. They have even been known to eat seagrass! Despite their large size, gray whales need to eat very little each day because their food is so energy-dense.
Are Grey Whales Bottom Feeders?
Yes, grey whales are definitely bottom feeders! They primarily eat benthic organisms that live in the sediments at the bottom of the ocean. These benthic organisms include amphipods, copepods, and euphausiids (krill).
Grey whales will also consume other small marine creatures such as squid, crab larvae, and small fish.
What are the Predators of a Gray Whale?
A gray whale’s predators include orcas, large sharks, and large dolphins. Orcas are the most common predator of gray whales, and they typically attack calves or sick adults. Large sharks will sometimes attack healthy adult gray whales, but these attacks are rare.
Large dolphins have been known to kill young gray whales, but this is also relatively rare.
Are Grey Whales Friendly?
Yes, grey whales are friendly! They are often seen interacting with humans and other animals in a variety of ways. For example, they have been known to rub themselves against boats and humans in a seemingly friendly manner.
Additionally, they have also been known to approach swimmers and even allow people to ride on their backs!
Conclusion
In short, grey whales eat a lot of small shrimp-like creatures called krill. They also eat other small fish, squid, and crustaceans.
