Whales

A whales urinary system has 2 kidneys, two ureters, a bladder and a urethra. Wuth the female, the urethra opens into the genito-anal slit. For the male, the penis is hidden in the genital slit, The anus is positioned closer to the posterior extremity of the body.

The pygmy right whale is among the least studied cetaceans (as of 2008 fewer than 25 "at sea" sightings of the species have been made). The species lives in the Southern Hemisphere and is believed to be circumpolar, living in a band from about 30 degrees south to 55 degrees south in areas with surface water temperature between 5 and 20 °C (41 and 68 °F). Individuals have been found on the coasts of Chile, Tierra del Fuego, Namibia, South Africa, Australia and New Zealand. One group may be a year-round resident off Tasmania. The total population is unknown.

The average weight of a mature orca is eight tons.

i think you ride on the left, going with the traffic, the opposite to walking but the same as cycling.

Whales have blue blood because of the low amount of hemoglobin in their blood

According to my friend Florence Atsley, straws do get stuck in dophin holes as said on Lizzie Maguire :)

Whales can generally only hear sounds that are made underwater. They have very good ears, because they 'talk' to each other using grunts and squeals over long distances.

Sound waves travel extremely well in water . . . much better than in the air.

No, Beluga Caviar comes from the Great White Sturgeon.

However, whales possess the largest physical brains of any animal. It has been found that whales possess spindle neurons, a type of brain cell which was considered to exist only in humans and other primates

states do not have whales, the oceans surrounding the east coast and west coast states contain whales.

Whale vomit is called Ambergris, and it is/was used in the perfume industry. It is highly valuable if it has been floating around for a few years, getting washed and polished by the sea and baked by the sun, losing its pungent smell and developing a sweet aroma. Current prices are around the £10 per gram mark.

The humpback is a predator, taking krill and small schooling fish, such as herring, salmon, capelin and sand lance as well as mackerel, pollock and haddock in the North Atlantic. Krill and copepods have been recorded from Australian and Antarctic waters. Humpbacks hunt by direct attack or by stunning prey by hitting the water with pectoral fins or flukes

Not really. It is more like what comes out of your nose and mouth when you sneeze. There is some water around the blow hole and when it opens to allow the dolphin to breathe, the water is sprayed out.

Whales breath air just like we do through their nose which in their case is the blowhole on the top of their head. If they do not make it to the surface every so often then they will drown. They can hold their breath because they have a large lung capacity.

Actually it is made out of whale blubber............ To prove this answer it is found on "Scholastic News" (Kids) it is about the whale capturing and stuff

Whales, dolphins, porpoises, orcas, turtles, seals, walruses, manatees, penguins, sea lions, sea elephants, catfish, snakeheads, alligators, crocodiles, snakes, etc.

The global whale population decreased from the heydays of Whaling, conducted by

Britain, United States, Norway, even Australia in the late 1800s to the early 1900s

by 70-80%. The IWC, International Whaling Commission put in place a gobal moratorium on comercial whaling in 1982. Since then certain species are believed to have recovered in great numbers, such as Minke Whales, while other species, such as Blue Whales remain on the endangered list.

Global Warming effects the whales by moving the Frontal zones (whale food areas) farther away. As global warming melts the sea ice, it also makes the frontal zones warmer. Global warming also messes up the warm currents that the whales normally swim in. Due to global warming, krill is dying out, and so there are less krill in some areas. For example, in California, the krill population is decreasing , so the whales along there have to look elsewhere for food. This causes the whales to get off track and loose their ways. Whales would follow the warm current and the krill. When whales migrate, to get to their frontal zones, it takes them a long way. If global warming moves those frontal zones, the whales would have to travel even farther. All this put together equals whales having to travel longer distance for food, less time for feeding, more competition for food. The frontal zones provide the whales with lots of nutrients and krill. This is their primary food source.

One must ask themselves if Whales care if they travel further though or if 0.5 degrees per 150 years years causes whales that much extra travel over a single year.

Man killing krill it would seem would have a far greater impact on where krill are for whales.

Cetaceans (whales, dolphins, and porpoises) are carnivorous creatures. The toothed whales (including dolphins) feed mostly on fish and squid, although the orca (killer whale) often hunts seals, sharks, and other cetaceans. The giant baleen whales (Blue whale, grey whale, humpback whale, etc), on the other hand, specialize in eating tiny planktonic crustaceans called krill.

Humans have been the biggest and most dangerous predators of the blue whales. With large ships and powerful harpoons humans killed these gentle giants in thousands. 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.
