Gray Whales

One way to stop it is by stopping poachers from hunting them.

About 2 years. But they almost allways have get togethers with their family members using sound because each pod has a different call to on and other so they can tell each other appart.

While the IUCN has listed the gray whale as "Least Concern" since 2008, the northwest Pacific gray whale subpopulation is listed as "Critically Endangered" and is also listed as "Endangered" by the US government's National Marine Fisheries Service. The International Whaling Commission has a subcommittee that re-iterated in 2011 that the risk to the western gray whale is large because of the small size of the population as well as anthropogenic impacts. Mexican law protects these whales while they are in their lagoons, while still allowing whale-watching. Canada's "Species At Risk Act" has identified specific threats to the western gray whales.

Humans have very little positive effect upon the Beluga Whale's environment. The Beluga is strictly Arctic. Global warming may make migration easier for the Belugas. This melts the ice caps making a quicker travel for the whales. However Global Warming has a very negative effect upon them and their environment as well.

Humpback whales are the greatest whales and travel the farthest in its migration Humpback whales are very big so they can basically travel in a sort of Wolf Packs.

For hundreds of thousands of years. 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

Baleen whales have a series of 130-180 fringed, overlapping baleen plates hanging like curtains from each side of the upper jaw. Baleen is made of a fingernail-like material called keratin. The plates are off-white and about 2-10 inch long. Baleen plates filter water out and trap food in, the baleen is replaced about every 5 years.

1 a year

No gray whales are killed.

Indigenous communities in Alaska kill 50 bowhead whales a year.

Adult gray whales can stay underwater for approximately 10 - 15 minutes.

as big as the universe! hahahahah have fun fooling around your teacher. By the way.... i know the real answer but i wont tell you! APRIL FOOLS! hahaha sorry...... sucks for you! by the way..... if you read this UR DUMB! hahahah fooled you again.

A gray whale female has babies close to california

we do not know if they do or not,we know that they take naps 10-20 min.

I think January, so in Winter.

It looks like they're only reallg getting protection by being listed as endangered, and defended when they were put on trial to be taken off the list (in oregon/california).

Convention on International Trade in Endangered Species of Wild Fauna and Flora, an international treaty with more than 144 member countries. Appendix I species cannot be traded commercially. Appendix II species can be traded commercially only if it does not harm their survival.

It affects many ecosystems in the ocean. For example, if there are no whales, the population of plankton or fish that are the whales food will increase. Also, the food chain is affected. Another reason why whale hunting affects the environment, is because the rare species of whales will get extinct.

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

because it is too cold for them to mate

all day

gray whales are black and gray with whale lice and barnacles and a triangle head and bumpy skin

Yes. 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

They are baleen filter feeders, eat tiny fish, krill, and plankton.
