Species Info:

This lifeform is found in northern Africa. This lifeform is found in Europe. This lifeform is found in Australia.

European Wild Rabbit (Sylvilagus cuniculus) is found primarily in Europe. However, this species has been introduced into Chile and Australia. In Australia, it has spread throughout most of the country and is now considered a serious and permanent pest. This rabbit is the ancestor of most of the commercial breeds of rabbits. Wild examples generally weigh less than five pounds.

Sylvilagus genus (cottontails) contains about 13 species,  most of which are native to North America.  However, several species are native to Mexico.  The forest rabbit is found from Mexico south to Bolivia and Argentina.

There are numerous species of wild rabbits, probably around fifty-seven in total, found widely in both the Old and New Worlds. They appear almost everywhere except the deepest rainforests. Several of the northern species of rabbits change the color of their fur to white during the winter months. Larger wild species can weigh up to ten or twelve pounds. Rabbits are generally fast-moving animals that can reach high speeds to escape the numerous predators that prey upon them. Rabbits generally eat green vegetation but in the winter months they will eat bark and twigs.

Rabbits (Order Lagomorpha) have habits and an appearance similar to rodents, but recent fossil studies indicate that rabbits are a distinct group of animals. To facilitate their study, the domesticated forms have been put into a separate subfamily.

Mammals (Class Mammalia), together with the birds, are among the youngest of the classes of animals. In species count, mammals number about fifty-one hundred, trailing reptiles (approximately fifty-five hundred), fish (approximately eighteen thousand), and birds (approximately eighty-six hundred).

There are three sub-types of mammals:

   monotremes, the most primitive:
      Develop in reptilian-like eggs and suckle milk emerging
      (i.e., spiny anteater, duckbilled platypus)

   marsupials
      Newborn emerges very underdeveloped and continue to
      mature in a pouch on its mother's abdomen (i.e., opossums,
      koala, kangaroo)

   placental  
      Embryo develops within the uterus of the female and is
      dependent on a placenta for nutrition and waste removal
      (i.e., humans, lions, monkeys)  

About sixty-five million years ago, the Tertiary era produced thirty-five orders of mammals. Of this number, eighteen have survived to represent Earth's most diversified as well as its most highly developed classification of animals.

Extinction of mammals is fast becoming a serious issue. Duff and Lawson present a list of forty-one extinct species that reached extinction prior to 1800. These forty-one species are not acknowledged in the counts of the various families. Duff and Lawson also present a list of forty-six species including three gazelles, one zebra, one seal, one deer, and one wolf that have probably gone extinct since 1800. These forty-six species are included in the family counts. Science is adding about forty to fifty new species a year to the list. Many of these are the result of divisions of prior species; some are recent discoveries.

Mammals owe their survival to adaptive capabilities that include the ability to exploit whatever sources of food are available to them, as well as their ability to adjust to various climes. Food specialization influenced evolution to such a great extent that the teeth structure can and has been used to provide extensive information on the food needs and various lifestyles of extinct species.

Despite the vast diversity among mammals in terms of size, habitats and adaptations, they share without exception many characteristics such as:  

    a. body hair
    b. mammary glands
    c. certain skull characteristics
    d. four limbs that permit speed
    e. parallel not perpendicular limbs
    f. compartmentalized internal organs
    g. a four-chambered heart and pulmonary circulation

Backboned Animals (Phylum Chordata) are the most advanced group of animals on earth. These animals are characterized by having a spinal cord or backbone. Most members have a clearly defined brain that controls the organism through a spinal cord. Fish, amphibians, reptiles, birds, and mammals are in this phylum.

Currently, some taxonomists believe that the fish should be divided into two groups (sharks and regular fishes) and that there are some other primitive groups in the phylum such as hagfish or lampreys.

Animal Kingdom contains numerous organisms that feed on other animals or plants. Included in the animal kingdom are the lower marine invertebrates such as sponges and corals, the jointed legged animals such as insects and spiders, and the backboned animals such as fish, amphibians, reptiles, birds, and mammals.
