What does a killer whale and a blue whale eat?
Killer whales often eat seals and often go for the babies of bigger whales like the blue and gray whales. Blue whales swim around with their mouths open to feed in so they catch krill. Then because they have baleen bristles instead of teeth, the water filters through that and they keep the krill.
How often do orcas breathe?
A whale needs air about every half hour. They have huge lungs that hold the air they need while they are underwater.
What are 5 sentences about blue whales?
1. Whales are very large animals that live in the ocean, but they are not fish! Millions of years ago, whales probably walked upon land. As many years passed, the whales changed. Their back legs disappeared and their front legs became flippers! Now they live in the ocean. 2.Whales are mammals, so they feed milk to their babies and breathe air. They like each other and live in large groups called "herds." A baby whale is called a "calf." Whales do not have gills, so they cannot breathe under water. They must come up to the surface of the water to get air. The air is breathed in and out through their "blowhole," which is on their back. When whales sleep, they stay at the top of the water, with their blowhole above the surface. Sometimes, a whale will swim up to the surface of the water and quickly blow air out of their blowhole, making a fountain of watery mist, called a "blow." 3.There are two different kinds of whales, the baleen and the toothed whale. Baleen whales are also called "toothless" whales. Instead of teeth, they have plates made of baleen in their jaws. Baleen is a very hard and strong substance, much like the material that makes animals' horns. Baleen is also called "whalebone." 4. he baleen plates grow from the whales' upper jawbones. They are from two to 12 feet long and they hang down in stringy pieces. Sea water passes through the baleen and the whales' food gets caught. A kind of plankton called krill is what the baleen whale eats. The biggest baleen whales eat as much as two tons of krill each day! There are many kinds of baleen whales, including blue, bowhead, Bryde's, fin, gray, humpback, minke, right and sei. The blue whale is the largest, often reaching 100 feet in length. They are the largest animals that have ever lived upon the earth. They are even larger than dinosaurs! Humpback whales are also big, weighing up to 45 tons. Baleen whales have two nostrils, or blowholes. 5. Toothed whales have teeth instead of baleen. They include the beluga or white, bottlenose, narwhal, pilot and sperm whales. Dolphins are toothed whales. The famous "killer whale," is really a large dolphin, and they can grow up to 30 feet in length. Toothed whales eat fish and plants. They have one nostril, or blowhole. 6.Whales swim by moving their tails up and down and using their flippers, which also help them to turn. Some whales, such as the sei, can swim more than 30 miles per hour. Flippers of the humpback whale can be as long as 15 feet. All whales are very noisy. They moan, groan, squeak and sigh to talk to each other. These underwater sounds can travel great distances. Whale are the loudest animals in the world. 7.Whales "migrate" further than any other animal. Migrating means to move from one area to another. In the warm summer months, whales feast to build up their blubber and other fat reserves. Then, as the weather and water begin to cool when winter approaches, the whales begin their migration to warmer places. They do not stop to eat, but swim almost constantly, stopping only to rest for short periods of time. For example, gray whales spend the winter months, from December into February, in the warm water of the Pacific Ocean near Baja California, Mexico. In mid-February they begin to swim north to the Arctic Ocean, Bering Sea, Chukchi Sea and the western part of the Beaufort Sea. They will stay in one of those areas until October, when they start the long swim back to the warmer Pacific Ocean off the coast of Mexico. Sometimes, as the whales are migrating, they swim very close to the shore and can be seen "blowing" and jumping out of the water. This jumping is called "breaching." Whale watching is popular in many coastal areas.
Where are whales in the food chain?
It largely depends on the whale. Toothed whales (such as the Sperm and Killer whales) are usually considered to be apex predators. Due to their size and hunting strategies their only main predator is humans (who are usually disregarded from such systems). Baleen whales (such as the Humpback and Blue whales) cannot be considered such as, though they are often protected by their immense size, their young are regularly hunted by other large predators, especially the toothed whales.
What types of whales get killed?
The smaller members of the Baleen whale (grey, minke) family often fall prey to other large marine predators such as toothed whales (sperm, orca, etc) and large sharks. This includes the young of the larger members (humpback, blue, etc).
Snakes breathe by means of which organ?
Snakes breathe using their lungs, like all reptiles. If they are underwater they have to come to the surface to breathe. Amphibians (frogs, newts, salamanders etc) are NOT reptiles. Amphibians often breathe through their skin.
The whales and dolphins often come up to the water surface they even release a fountain of water sometimes while moving upwards why do they do so?
That's how they breathe, Mammalian fish such as the whale or dolphin need air to breathe just as much as they need water to swim in. When they break the surface and blow out the water they also take in a breath of air before diving back down
Do whale sharks have to surface?
Whale Sharks are Sharks "big as a whale". They Breathe with gills and don't have to Surface. They often do though, b/c they find a lot of food Close to the Surface.
Do sharks and whales get along with each other?
Sharks and whales are actually not related to each other. A shark is a type of fish. They breathe through gills, and do not nurse their pups. Whales are mammals. They are warm blooded, breathe surface air, and nurse their calves. The animal that is probably the closest relation to the whale would be a dolphin. Certain types of dolphins, such as orcas, are often mistaken for whales.
What is the food of an cetacean.?
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.

What is the difference between how reptiles breathe and how amphibians breathe?
Reptiles (snakes, lizards, crocodiles etc) breathe using lungs. If they are underwater they have to come to the surface to breathe. Amphibians (frogs, newts, salamanders etc) are NOT reptiles. Amphibians often breathe through their skin. They can also gulp air into their primitive lungs using their mouth or throat.
