| − | <!-- 1. In what way is the Cetaceans family different from most other sea life? --> | |
| − | The Cetacean family is different from most other sea life because Cetaceans are mammals.

| − | This means :
| |
| − | * '''A:''' They give birth to live babies. The largest whale is the Blue Whale and its newborn baby will be up to 7 meters long and weigh up to 2700 kg/6,000 lbs, (about as much as two cars).
| |
| − | :The large whale mothers move to warm tropical waters to give birth and spend about six months there so their babies can grow a layer of fat (blubber) to help them survive the cold frigid waters where they live for the other six months. While in the warm waters the adult whales do not eat at all.

When they want to breathe they come to the surface, blow out moist air from their lungs and snatch a new breath. Their nostrils are called blowholes. Baleen whales have two blowholes and toothed whales one blowhole. The whale hunters could tell what sort of whale it was by the shape of the spout blown out.

| − | In addition to the characteristics of mammals listed above, cetaceans differ from other sea life in other ways as well. One of these differences between a cetacean and a fish is the shape of the tail. The tail of a fish is vertical and moves from side to side when the fish swims. The tail of a cetacean – called a "fluke" – is horizontal and moves up and down.

| − | The order Cetacea contains about 90 species, all marine except for four species of freshwater dolphins. The order contains two suborders: Mysticeti (baleen whales) and Odontoceti (toothed whales, which includes dolphins and porpoises). The species range in size from Commerson's dolphin, smaller than a human, to the blue whale, the largest animal ever known to have lived.

| − | ===Baleen Whales===
| |
| − | The baleen whales, also called whalebone whales or great whales, are one of two suborders of the Cetacea (whales, dolphins and porpoises). Baleen whales, rather than having teeth, have baleen plates which hang from the upper jaw and are used for filtering food from water. This distinguishes them from the toothed whales. Baleen is a type of hair but stiff like a soft fingernail. It grows from the roof of the mouth in two rows and is used to filter out food from water.
| |
| − | [[Image:Baleen.jpg|thumb|250px|Baleen]]
| |
| − | The whale is able to take in a huge mouthful of water and then squeeze its mouth shut and squeeze out the water while straining out the food. Baleen whales feed on tiny creatures called krill and need lots of these to fuel their bodies. Most of the big whales are baleen whales, e.g. Blue whale, humpback whale and fin whale. Krill is one of their major foods, which they strain through their baleen.

| − | Baleen whales are generally larger than toothed whales, and females are larger than males. This group includes the Blue Whale, the largest animal species that has ever lived. Baleen whales have two blowholes, causing a V-shaped blow whereas toothed whales have a single blowhole.

| − | ===Toothed Whales===
| |
| − | The toothed whales have teeth because they feed on creatures much larger than krill, such as squid, fish seals and even other whales. These whales are the dolphins and porpoises, the killer whale and the giant sperm whale.

| − | <!-- 3. In what way have Whales and Dolphins been a benefit to man? --> | |
| − | In some cultures, whales provide meat for both pets and for humans. Whales also provide oil for fuel, perfumes, and other products. Entire communities were established devoted to whaling. Although whaling is now illegal in most parts of the world, whales continue to provide benefits to man. They are a major tourist attraction in areas where they are common, and an entire industry has sprung up to bring people to see the whales.

| − | There are many stories of dolphins protecting shipwrecked sailors against sharks by swimming circles around the swimmers. Because of their high capacity for learning, dolphins have been employed by humans for any number of purposes. Dolphins trained to perform in front of an audience have become a favorite attraction at many aquariums, for example SeaWorld. Such places may sometimes also provide an opportunity for humans to interact very closely with Dolphins. Dolphin/Human interaction is also employed in a curative sense at places where dolphins work with autistic or otherwise disabled children. The military has employed dolphins for various purposes from finding mines to rescuing lost or trapped persons.

| − | <!-- 4. Explain how it is that a Whale which breeds in the warm waters of the tropics can also survive the ice cold water of the Antarctica where they go to feed, (considering the whale is a warm blooded mammal like humans). --> | |
| − | Whales have a very thick layer of fat beneath their skin called ''blubber''. Blubber is a very effective insulator, much like a wet suit which is used for keeping divers warm when they swim in cold waters. Blubber is far more effective than a wet suit because it is so thick. In fact, blubber can comprise up to 50% of the body mass of some cetaceans during some points in their lives. Blubber also serves as a source of energy, and whales ''metabolize'' (burn) fat to generate heat internally and thus warm themselves. People metabolize fat too when they shiver (shivering serves the same purpose - to warm us up).

| − | ====Family Physeteridae: Sperm Whales====
| |
| − | There are three species in the sperm whale family, including the largest toothed predator in the world and smallest whale in the world. A common characteristic of these species is the spermaceti, a semi-liquid waxy white substance filling the 'case' or spermaceti organ in the whale's head, which is thought to be involved in providing ballast for diving and maintaining buoyancy. This may be done by flushing cold water through the nose, hardening the spermaceti, to dive, and pumping warm blood to melt the spermaceti to surface. All three species dive to great depths to find food, although the sperm whale is believed to dive much deeper than either of its smaller cousins. Sperm whales eat squid, fish, and even sharks.

| |
| − | There are 22 recognized species of Beaked Whales, toothed whales notable for their elongated beaks. Of air breathing animals, beaked whales are some of the most extreme divers. Cuvier's beaked whales regularly dive for an hour at a depth over 1,000 m (3,300 ft), and the longest and deepest foraging dive recorded is 137.5 minutes and 2,992 m (9,816 ft).

| − | Beaked whales are one of the least known groups of mammals because of their deep-sea habitat, mysterious habits, and apparent low abundance. Only three to four of the 22 species are reasonably well-known. Baird’s and Cuvier's beaked whales were subject to commercial exploitation, off the coast of Japan, while the Northern bottlenose whale was extensively hunted in the northern part of the North Atlantic late in the 19th and early in the 20th centuries.

| − | ====Family Phocoenidae: Porpoises====
| |
| − | Porpoises are small cetaceans that are distinct from dolphins, although the word "porpoise" has been used to refer to any small dolphin, especially by sailors and fishermen. The most obvious visible difference between the two groups is porpoises have spatulate (flattened) teeth distinct from the conical teeth of dolphins. Porpoises rear more young more quickly than dolphins. They have small flippers, notched tail flukes, and no beaks. All carry at least 11 pairs of small teeth in their upper and lower jaws.

| |
| − | | range = The Finless Porpoise lives in the coastal waters of Asia, especially around India, China, Indonesia and Japan. A unique fresh water population is found in the Yangtze River. At the western end, their range includes the length of the western coast of India and continues up into the Persian Gulf. Throughout their range, the porpoises stay in shallow waters (up to 50m), close to the shore, in waters with soft or sandy seabeds. In exceptional cases they have been encountered as far as 100 miles off-shore in the East China and Yellow Seas, albeit still in shallow water.
| |
| − | | description = The Finless Porpoise almost completely lacks a dorsal fin. Instead there is a low ridge covered in thick denticulated skin. Adult Finless porpoises are a uniform light grey color. Infants are mostly black with grey around the dorsal ridge area, becoming grey after 4-6 months.

| |
| − | | description = The Harbour Porpoise is a little smaller than the other porpoises. It is about 75 cm long at birth. Males grow up to 1.6 m and females to 1.7 m. The females are correspondingly heavier, with a maximum weight of around 76 kg compared with the males' 61 kg. The body is robust and the animal is at its maximum girth just in front of its triangular dorsal fin. The beak is poorly demarcated. The flippers, dorsal fin, tail fin and back are a dark grey. The sides are a slightly speckled lighter grey. The underside is much whiter, though there are usually grey stripes running along the throat from the underside of the mouth to the flippers.

| |
| − | Dolphins, including the river dolphins, comprise 45 species out of the 90 Cetacean species. Six species in the family Delphinidae are commonly called "whales", but genetically are dolphins. They are sometimes called blackfish. These are the Melon-headed whale, (Peponocephala electra) Killer whale/Orca (Orcinus orca). Pygmy killer whale, (Feresa attenuata), False killer whale, (Pseudorca crassidens), Long-finned pilot whale, (Globicephala melas) and the Short-finned pilot whale (Globicephala macrorhynchus)

| |
| − | | description = The Bottlenose Dolphin is the most common and well-known dolphin species. They are gray, varying from dark gray at the top near the dorsal fin to very light gray and almost white at the underside. This makes them harder to see both from above and below when swimming. The elongated upper and lower jaws form what is called the rostrum and give the animals their name of Bottlenose. The real nose however is the blowhole on top of the head, and the nasal septum is visible when the blowhole is open. Their face shows a characteristic "smile".

| |
| − | | range = The common dolphin is widely distributed in temperate, sub-tropical and tropical waters throughout the world in a band roughly spanning 40 degrees south to 50 degrees north. The species typically prefer enclosed bodies of water such as the Red and Mediterranean Seas. Deep off-shore waters and to a lesser extent over continental shelves are preferred to shallow waters. Some populations may be present all year round, others appear to move in a migratory pattern. Preferred surface water temperature is 10-28 degrees Celsius.
| |
| − | | description = Common dolphins travel in groups of around 10-50 in number and frequently gather into schools numbering 100 to 2000 individuals. These schools are generally very active - groups often surface, jump and splash together. Typical behavior includes breaching, tail-slapping, chin-slapping, bow-riding and porpoising.
