Why are giraffes and whales mammals?
Giraffes are classed as mammals. They are not related to retiles in any way.
They are classed as mammals because they are vertebrates (They have a backbone, or spine), they are endothermic (this is sometimes called "warm blooded", and basically means they regulate their own boy temperature by using internal mechanisms, like sweating and panting), they have hair on their bodies, and they produce milk to feed their young, as well as giving birth to live young.
Reptiles on the other hand are completely different. They are Ectotherm (this is what's known as "cold blooded" and means they use external means, such as basking the sun to warm up, or hiding in the shade to cool down), they have scales instead of hair, and they lay eggs instead of giving birth to live young, and do not produce milk for them, as hatchlings do not need it.
You must have Black Clay and White Clay. You must make a big ball with your Black Clay. Then, make a cone shape with Black Clay. Then make the eyes by putting small balls of Black Clay on round flat pieces of White Clay. Then attach this to the front of the big ball of Black Clay. Then, use a spoon and put it into the middle of the clay below the eyes. Then cut out triangles of cardboard and stick it in the back of the clay ball. Then paint it black. Turn your Orca upside down and add white clay for the underparts.
How many species of whales are there in california?
The Humpback Whale is not in California. It is in the Pacific Ocean near California. The Humpback Whales migrate every year up and down the coast of California, down to Hawaii. There are also Humpback Whales in the Atlantic Ocean and in the Pacific Ocean surrounding the NW, W, SW, S, and SE coasts. It all depends on the time of year as to where the Humpback Whales will be as well as where they have grown up and lived their whole life.
The Southern Right Whales are marvelous creatures. Right whales were named by whalers who thought they were the "right" kind of whales to hunt. Since they were loaded in blubber, they were easy to catch and they floated after being killed. The whale's skin is a brown to dark gray with white patches near its mouth. Like the other baleen whales right whales have no dorsal fins.
The heads of these whales are hairier than others. There can be found up to 300 hairs near the tip of the lower jaw and close to 100 on the top. They also have callosities behind the blowhole, on the chin, above the eyes, on the lower lip, and on the rostrum. Callosities themselves are grey; the reason it appears to be white due to large colonies of whale lice around them.
Has a basking shark ever attacked a human?
No. Very few shark species will attack a human unprovoked . Often, in stories one hears, a shark mistakes the figure of a human on a surf board for a seal. The best way to avoid sharks is to avoid splashing and not to cut yourself.
The female narwhal is called a cow. The male is called a bull. And the baby is called a calf.
What are some interesting facts about blue whales?
Some of the answer is blue whale is definitely the largest living warm blooded sea mammal ever existed on this planet and sometimes can reach a length of 30.5 meter (100 feet) and weigh over 100 tons.
On land an animal the size of a blue whale would be crushed by its own weight without the support of large heavy bones. Because its body is supported by water, as a sea animal, the need for heavy bones to support its weight disappeared. This, plus the availability of a large food supply, have made it possible for the blue whale to reach such an enormous size. The blue whale makes deep and rumbling sounds which can be felt as much as heard. These low frequency sounds travel long distances through water, allowing blue whales to communicate with each other over hundreds of miles of ocean.
Their scientific name is Balaenoptera musculus.
Also, in the 20th century, 99% of the Blue Whale population was killed by whalers!
What is so special about minke whales?
There are few interesting facts about Minke Whales, look at 2 following examples. Minke whales are generally solitary, although they can sometimes be seen in groups of 2 or 3. Minke whales are highly inquisitive and are likely to approach boats, especially younger animals.
Why can t whales just swim under water all the time?
The reason whales die rather quickly when they're stranded on a beach is two things. First, their bones are lightweight and porous, much lighter than the bones of land animals. this is because, in the water, the bones don't have to provide the kind of support that ours do on land, so they've evolved more as places for muscles to attach to than for actual support. On land (away from the buoyant water where gravity isn't a big factor), the whale literally crushes itself under its own weight. Second, they overheat. Most whales are designed to live in cold water, which takes heat out of a body some 20 times faster than air does. Their fat (blubber) insulates them very well in the water. On land, however, they dont have the cooling of the water, and the blubber makes them overheat. Dead whales literally cook inside, since after death the thermoregulatory mechanisms that normally cool the animal are shut down, and decomposition sets in, inside what is essentially a big pressure cooker (the body).
The word school (or shoal) isn't defined by a specific number but simply means 'a large group or multitude', similar to words such as flock (of sheep/birds), gaggle (of geese), herd(of cattle), swarm (of bees), pack (of hounds), business (of ferrets), mob (of kangaroos), mess (of iguanas), pride(of lions), plague (of locusts) or murder (of crows).

Calf is the Word used for the (very) Young of certain animals. A baby of one of those species.
You can't have a calf of a baby. It'll be like having a baby of a baby. Doesn't happen. A baby is a Young, sexually immature living thing. It can't reproduce.
What is a Description of a whale?
Orcas are very efficient hunters so they eat a nice amount of sharks, whales, seals, penguins, dolphins, and more sea creatures. They even attack large baleen whales and even the biggest whale, blue whales! Orcas that are average sized eats up to 551 pounds a day. That's probably more than you weigh! Orcas hunt in big groups. Orcas have very sharp teeth but they do not chew, they use their sharp teeth to tear apart their prey to share it with the other orcas. Orcas swallow their food whole. They hunt together by surrounding the prey and trying to grab the prey before the prey tries to run away. The orca is a carnivore and loves meat. Orcas that may possibly get sick and weak may get caught and eaten by other predators like a polar bear or possibly sharks.
Filter feeders are organisms that are mainly found underwater. They eat using the method of 'filter feeding' where-by they simply just open their mouth and take in whatever happens to be their (nutrients in water), whilst filtering the undesirable parts.
Does a giant squid have a big mouth for eating small whales?
Giant squids don't have big mouths. Compared to body size they have a fairly small beak-like mouth they use to bite chunks large enough to swallow out of their prey.
And whales - even "small whales" are too big for a giant squid to attack successfully.
How fast does a whales heart beat?
9 times per minute, or every 6.7 seconds 9 times per minute, or every 6.7 seconds
What is the niche of the Sei Whale?
niche how organisms get what they need in order to survive. a right whale's niche is putting them in danger. because they live near the coasts, and they are surface feeders (food for survival) they are very easy targets.
that is my answer but i don't know anything more
whales are captured by the whaling ships harpoons, which are found at the front of the ships. They fire large arrow like harpoons into the vonuable spots of the whales and then some how bring them around to the back of the ship and dragged up a acess ramp to be chopped up. i think they use it like boats to pull them around.
How small is the smallest whale?
The smallest whale in the world is the Dwarf Sperm Whale; a member of the Sperm whale family that reaches a maximum of 2.7 meters long and a maximum of about 272 kilograms. This whale is found in many of the world's oceans, but is elusive to the extent that we don't know what their world wide population is. One of the reasons that we know so little about this whale is that until the 1960′s it was thought to be the same as the Pygmy Sperm Whale, and although they are similar, they are definitely not the same whale.
A crane used at the Avedore Power Station in Denmark weighs 360 tons. The crane is capable of moving up to 800 tons of wooden pellets per hour.
