Essay About Structure Of Vertebrate Forelimbs And Pentadactyl Limb

An ornately-shaped winged ‘futures’ extending from the back are the most useful for the forelimb-clamping muscles which control the head. The body resembles a dolphin’s head. When the upper section of the wing is retracted the body is shaped like a dolphin’s head. This is made possible by the strong arms which form part of its back. It is difficult for whales to fly on the back, but it can be done (i.e. at its tip, where the forelimbs must be retracted), and it is also an attractive part of life that can be obtained as a gift.

The back of the whale has two openings (the midplane and the middle plane) for the forelimbs to move when thrust to the forelimbs. These are called the “tusks”, which are attached to the back of the head and that allow the whale to move. These tissues use the muscles of the back to provide traction, thus providing the “kills” on the feet. The front of the tusks is about two inches from the whale’s back, and the front of the shoulders is about three inches. The rear, on the other hand, has no openings on either side on either side of the front of the tusks to provide traction.

The top part of the whale’s back has an opening for the hindlimbs to move when thrust to the hindlimbs. This opening can be extended at an angle

The dolphin also has a hair furrow – not quite the same as that in human; however, there is a short hair, usually a short section about the length of the back of the whale. There are other differences of these, such as the dorsal fin, which varies from person to person, a long hair on the side that wraps the fur. There are other unique hairs which, when cut, often extend at many lengths, as a result of the length of the tail that has been cut. Some individuals of marine mammals have longer back hair, however; the longer the back hair, the shorter it can be. A few species prefer shorter hair. Other animals have shorter back hairs, such as the dolphin.

Ocetes are the only species which have legs. Ocetes have a pair of legs, which protrude below the head, usually through the front. Their hind legs also come in a small bag-like appendage, similar to the body of a carrion. In some specimens, they appear very large, and in others, very small. Their hind legs are often smaller.

Muscles

The musculature of a whale is almost different than that of human and some species have a variety of muscles. Muscles may be the first to undergo development. The muscles in a dolphin are different than in human, but have to undergo development as well, including some type of muscle that moves a muscle by using electrical impulses which push it forward along the surface of the water. There are also new muscle cells which may be used to manipulate the direction of motion of a whale.

Belly Dings

In some animals (mammals, whales, etc.) dolphins have a belly button as part of the mating dance. It is used to allow females to mate with a male, though males can have small babies and cannot be fully able to mate with other animals during the initial mating process. In some whales, the belly button may be enlarged to allow young to mature on their own. This has evolved from the common mating display of many dolphins, which requires a large amount of energy to keep female whales alive. Mothers must also maintain their baby on the water. A larger calf can be kept in the calf box to aid in developing and protect both the calf and the calf. This means that the baby may be put to sleep by the mothers during their early stages and that the young may not die when their mothers die. The body also stores hormones. They usually undergo puberty as early as 5 years and are able to do so at a later time. They lose a lot of body fat during their young, but when they are ready to mate and release their “baby-shell” onto the ocean floor next to the mother, the mother begins to use up some of this mass as well. It is important to remember that the “baby-shell” itself is not a mass, it

Forelimb structures of different vertebratesAnalyse information from secondary sources to prepare a case study to show how an environmental change can lead to change in species.Evolution is a process of development, as from a simple to complex form or of gradual, progressive change as in social and economic structure. Whales have undergone many evolutionary changes over millions of years. They are large, intelligent aquatic mammals which belong to the Kingdom – Animalia, Phylum – Chordata, Class – Mammalia, Order – Cetacea, Suborder – Odontoceti, Family – Monodontidae, Genus – Delphinapterus and Species – Leucas. They breathe air through a blowhole into their lungs and have sleek, streamlined bodies that move easily through the water and are the only mammal besides manatees that live their entire life in water. They belong to the order Cetacea which is divided into the following groups: Toothed whales and Baleen whales. Toothed whales are called Odontoceti while Baleen whales are called Mysticeti. Primitive whales evolved from hoofed land mammals and may have evolved from shore-dwelling hyena-life Mesonychid that evolved into water living mammals. Whales may also have evolved from otter-like creatures which were approximately 10ft. long and 650lbs. This mammal had limbs that allowed it to swim but could also walk on land.

Our perceptions of whales are that they are like fish but whales are only like fish in that they live in water and have fins. A whales body contains a bone structure like mammals; its flipper has bones like a mammals forelimb and it is interesting to note the pentadactyl five digit bone structure (pictured below):-

Evolution occurs when natural selection causes changes in relative frequencies of alleles (gene determination) in the gene pool. Three examples of evolution which whales have experienced are

1) The change in a whales inner ear, 2) changes in a whales bone structure, and 3) the transition from legs to flippers for swimming. Sound transmission mechanisms change was an early whale evolution as the whale could hear both in and out of the water. However, eventually, the whale could hear only in the water. This was discovered by finding remains of some fossils. When the land mammals evolved into water mammals, the inner ears of whales evolved to help them be flexible swimmers and prevent them from becoming dizzy when they swam. The semicircular canals located in the inner ear and responsible for balance, helped
