Aquatic Mammals

Blue Whales are the largest known living animal species on earth. Animals that were as large as 27 meters in length (nearly 90 feet) and weighing over 170 tonnes have been recorded. Since these animals were measured and weighed after they were cut up into manageable pieces, the actual size and weight could be even more

The fastest thing on the ocean would be a speed boat. The fastest fish in the ocean is debatable the sailfish has been clocked at 70 mph, and the black marlin has been clocked at speeds of 80 mph.

In special cases certain fish may swim faster or slower, and who can say if those fish that were recorded were swimming their fastest. One thing is for sure, the fastest fish in the ocean, is definitely in the Istiophoridae (billfish) family.

I think it's because they are two different species of seal.

Most whales are considered to be picky about what they eat. Gray whales are the only ones that are known as not being picky and can eat pretty much any type of food.

Whales do not lay eggs, they give birth to live young.

The blue whale has several adaptations that help it survive in its habitat. They include blubber for warmth, a sleek shape for swimming and they never need to sleep.

In Southeast Alaska, mainly humpbacks. You can also see killer whales and Dall's and harbor porpoises. In Cook Inlet you can see beluga whales. Off Kodiak Island you can see fin and humpback whales. In northern Alaska, you can see bowhead whales.

Not the kind we have on the coast, or the bottle nose dolphin. Killer whales are though if you like them.

Additional Information: There are almost 40 different species of Dolphin. Of those 40 species, 36 species are listed by the International Union of Conservation for Nature, or the IUCN Red List with a status anywhere from "data deficient" to "critically endangered". The following is a list with the Dolphins listed by the IUCN Red List as endangered, and critically endangered.

Hector's Dolphin "Endangered" population "Decreasing"

Yangtze River Dolphin "Critically Endangered" population "unknown" possibly extinct.

South Asian River Dolphin "Endangered" population "Decreasing"

Dolphins DO live in the tidal regions of many rivers. Along with seals, manatee and dugong, they are commonly seen up to 50 -80 miles from the sea. -While canoeing in our Fraser River in British Columbia, I have often seen seals 60 miles from the Georgia Strait.

they can live for up to 10 to 12.5 years it depends on the cat

Adult hippos can't swim. This may seem odd since they do spend a lot of time in the water. They hold their breath well and are adapted in many ways for semiaquatic life. But they can't swim. In fact adult hippos can't even float, probably because they're too dense, and although they look fat, their percentage of fat is low.

Yes, Beluga whales are found in the Arctic Ocean, along the coasts of Alaska, Canada, Greenland and Russia. In the adjoining seas of Sea of Okhotsk, the Bering Sea, the Gulf of Alaska, the Beaufort Sea, Baffin Bay, Hudson Bay and the Gulf of St. Lawrence Seaway. Belugas are well adapted to both a cold ocean habitat (0 degrees Celsius) and warmer freshwater habitat.

the basic needs of a sea otter is an ocean, salt, food, and water

they form a tight circel around their young and make fast lunges at the thing that is threating them

they are a vertebrate because their are mammals, and and all mammals are vertebrate because they have internal skeletons with a backbone.

They use it to find were they are going, such as the toothed whale or a blue whale. Hope this is useful! :D :) ;D

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.

it was all gods creation at the start.

The same grey, mottled coloring as a drowned sailor is the color that generally is given for the narwhal. The color in fact may be varied by age since baby narwhals tend to have darker, black and white mottling. With age, mature narwhals take on whiter and whiter appearances.

Dolphins and whales are not classified as fish; they are marine mammals belonging to the order Cetacea. Unlike fish, which are cold-blooded and breathe through gills, dolphins and whales are warm-blooded, breathe air through lungs, and give live birth. They share common characteristics with mammals, such as having a layer of blubber for insulation and being social animals. Their aquatic lifestyle and similar habitats can sometimes lead to misconceptions about their classification.

the narwhal would be the closest relative to the beluga. they share the rounded forehead and the lack of dorsal fin. Hope that answers your question. :P

It's because they need salt water in oceans,but there are river dolphins that need river water.

yes its a type of fish but bigger than an ordanary fish!

orso an octopus is a false type of fish!!

Sea Urchins only eat see grass and algae. I hope that helps!
