Gray Whales

The Gray Whales food chain should include: Animal with competitors; foods including plants; predators and the sun:

Competitor: Killer Whale

Foods: Amphipods (small shrimp like animals), Crab Larvae, Herring eggs, etc.

Predators: Killer Whale, Sharks, and human.

Gray whales are baleen whales. The Sperm whale is the only really big toothed whale.

1,100 to 1,200 centimeters.

They call them PODS and they travel in pods most of the time.

Breeding behavior is complex and often involves three or more gray whales. The Gestation period is about one year, and females reproduce biennially. The calf is born tail first, and measures about 4 meters in length at birth. The Gray Whales give birth to their young in shallow lagoon waters. This is done to protect the newborn from predators like sharks and orcas

Grey or Gray Whale (eschrichtius robustus)

can be found in the Eastern North Pacific (North America) - critically endangered

Gray Whales have been hunted since the 16th century. Humans have been whaling gray whale species for over 4 decades now. This hunting has significantly reduced the gray whale populations. The north atlantic population of gray whales were totally wiped out due to whaling even before the 19th century. Around 1950, governments worldwide declared the gray whale as an endangered species and banned whaling them

I cannot. Because, Adult blue whales have no natural predators. They are too big and too strong to be attacked and killed by any animal. However, Orca's (Killer Whales) are known to attack and kill youngsters. A group of Orca's can easily hunt a baby blue whale if its mother is not around. Otherwise, they have no natural predators

Adult, healthy whales are large and powerful enough that the only predator that they need fear is man. Humans have hunted grey whales for millennia. Young, sick or injured whales could be food for sharks, orca, or any other large and fast oceanic carnivores.

Blubber for warmth- streamline body for better swimming and its teeth act as a sieve to filter krill out of the water. and lastly it takes naps instead of long sleeps because if it does it would drown.

Orca's are the only known natural predator of the gray whale. Groups of Orca's can easily kill a mid sized gray whale. Full grown adults are too big for even a group of Orca's to kill. But, babies are especially vulnerable. The Gray Whales give birth to their young in shallow lagoon waters. This is done to protect the newborn from predators like sharks and orcas

During the summer they live in the murky waters of the Arctic Sea while they feed. Then in Autumn they start a migration to the Baja California peninsula in Mexico, where they live during the winter in shallow lagoons when they reproduce. Juveniles and calves also enter the lagoons though they do not reproduce. On early spring they begin they journy back to the Arctic.

they live in cold water.

Gray whales eat prey from the seafloor. They commonly eat shrimp-like creatures called Amphipods. They do not eat Coho salmon.

Yes, Gray Whales are endangered, but they are starting to make a comeback. Here is some information I found on WWF.org about the Gray Whale: == "Intensive exploitation has much reduced population numbers of this species over the last three to four centuries. Of the original three gray whale populations, one is extinct in the North Atlantic, one is Critically Endangered (IUCN Red List status) in the Western North Pacific (with as few as 100 individuals remaining), and one has recovered from very low levels in the Eastern North Pacific and was removed from the U.S. Endangered Species List in 1994.

WWF and its conservation partners have been instrumental in strengthening protection for the north-west Pacific gray whales. The organization succeeded in curtailing seismic surveys that were shown to displace gray whales from their feeding ground and has been urging the Russian government to establish a gray whale sanctuary off Sakhalin Island.

Other activities include pushing for stricter environmental standards for offshore oil and gas projects, engaging a local energy company regarding their operations, and running a public campaign to raise awareness regarding the threats posed by the Sakhalin offshore oil and gas projects pose to whales."

To escape the frosty winter in the north. Each October, as the northern ice pushes southward, small groups of gray whales in the eastern Pacific start a two to three-month, 8,000-11,000 kilometers trip south. Traveling night and day, the gray whale averages approximately 120 kilometers per day at an average speed of 8 kilometers per hour. This round trip of 16,000-22,000 kilometers is believed to be the longest annual migration of any mammal

Gray Whales are known to live between 50 to 70 years of life. Though they have a long life expectancy, human hunting has prevented them from living so long. Over the past decade hunting has stopped (not fully but significantly) and hence they may live to their max life of 70 years or so

The California coast is an excellent place to see gray whales as they migrate.

Seal blubber can be two inches thick underneath the skin. This could average about 528 pounds of pure blubber which helps them stay warm during cold temperatures.

Blue Whale populations have declined significantly due to extensive and uncontrolled hunting. Blue whale hunting was banned in 1966 by the International Whaling Commission. But, by 1970 330,000 blue whales had been caught & killed in the Antarctic, 33,000 in the rest of the Southern Hemisphere, 8,200 in the North Pacific, and 7,000 in the North Atlantic. The largest original population, in the Antarctic, had been reduced to 0.15% its original count.

Now that the hunting of these giant animals is banned, their numbers has started to increase and I don't think they will go extinct.

Gray Whales feed on benthic crustaceans that are found on the sea bed. The whale scoops up sediments from the sea floor and filters out edible particles and feeds on them. Crustaceans like Krill, small lobster, shrimp etc would form the food chain of the gray whale.

yes gray whales are mammals. They are marine mammals.
