    BASIC FACTS ABOUT DOLPHINS

    Dolphins are highly intelligent marine mammals and are part of the

    family of toothed whales that includes orcas and pilot whales. They are

    found worldwide, mostly in shallow seas of the continental shelves, and

    are carnivores, mostly eating fish and squid. Dolphin coloration varies,

    but they are generally gray in color with darker backs than the rest of

    their bodies.

    DietDolphins consume a variety of prey including fish, squid and crustaceans.

    PopulationIt is difficult to estimate population numbers since there are many

    different species spanning a large geographic area.

    Range Did You Know?

     Like bats, dolphins use echolocation to navigate and hunt, bouncing high-pitched

    sounds off of objects, and listening for the echoes.

    Most species live in shallow areas of tropical and temperate oceansthroughout the world. Five species live in the world's rivers.

    BehaviorDolphins are well known for their agility and playful behavior, making

    them a favorite of wildlife watchers. Many species will leap out of the

    water, spy-hop (rise vertically out of the water to view their surroundings)

    and follow ships, often synchronizing their movements with one another.

    Scientists believe that dolphins conserve energy by swimming alongside

    ships, a practice known as bow-riding.

    Dolphins live in social groups of five to several hundred. They use

    echolocation to find prey and often hunt together by surrounding a school

    of fish, trapping them and taking turns swimming through the school and

    catching fish. Dolphins will also follow seabirds, other whales and fishing

    boats to feed opportunistically on the fish they scare up or discard.

     Did You Know?

    To prevent drowning while sleeping only half of the dolphin’s brain goes to sleep

    while the other half remains awake so they can continue to breathe!

    ReproductionMating Season: Throughout the year, though in some areas there is a

    peak in spring and fall.Gestation: 9-17 months depending on the species.

    When it is time to give birth, the female will distance herself from the

    pod, often going near the surface of the water.Number of offspring: 

    Usually one calf; twins are rare.As soon as the calf is born, the mothermust quickly take it to the surface so it can take its first breath. The calf

    will nurse from 11 months to 2 years, and after it is done nursing it will

    still stay with its mother until it is between 3 and 8 years old.

    BASIC FACTS ABOUT ELEPHANTS

    Habitat loss is one of the key threats facing elephants. Many climate change 

    projections indicate that key portions of elephants’ habitat will become significantly

    hotter and drier, resulting in poorer foraging conditions and threatening calf survival.

    Increasing conflict with human populations taking over more and more elephant

    habitat and poaching for ivory are additional threats that are placing the elephant’s

    future at risk.

    © Geoff Hall

    Defenders of Wildlife is working through the Convention on International Trade in

    Endangered Species (CITES) to maintain a ban on the sale of ivory as well as on

    regulations that govern worldwide elephant protection.

    Of the two species, African elephants are divided into two subspecies (savannah and

    forest), while the Asian elephant is divided into four subspecies (Sri Lankan, Indian,

    Sumatran and Borneo). Asian elephants have been very important to Asian culture for

    thousands of years – they have been domesticated and are used for religious festivals,

    transportation and to move heavy objects.

    Staples: Grasses, leaves, bamboo, bark, roots. Elephants are also known to eat cropslike banana and sugarcane which are grown by farmers. Adult elephants eat 300-400

    lbs of food per day.

    Population

    At the turn of the 20th century, there were a few million African elephants and about

    100,000 Asian elephants. Today, there are an estimated 450,000 - 700,000 African

    elephants and between 35,000 - 40,000 wild Asian elephants.

    Range

    African savannah elephants are found in savannah zones in 37 countries south of theSahara Desert. African forest elephants inhabit the dense rainforests of west and

    central Africa. The Asian elephant is found in India, Sri Lanka, China and much of

    Southeast Asia.

    Behavior

    Elephants form deep family bonds and live in tight matriarchal family groups of

    related females called a herd. The herd is led by the oldest and often largest female in

    the herd, called a matriarch. Herds consist of 8-100 individuals depending on terrain

    and family size. When a calf is born, it is raised and protected by the whole

    matriarchal herd. Males leave the family unit between the ages of 12-15 and may leadsolitary lives or live temporarily with other males.

    Elephants are extremely intelligent animals and have memories that span many years.

    It is this memory that serves matriarchs well during dry seasons when they need to

    guide their herds, sometimes for tens of miles, to watering holes that they remember

    from the past. They also display signs of grief, joy, anger and play.

    Recent discoveries have shown that elephants can communicate over long distances

    by producing a sub-sonic rumble that can travel over the ground faster than sound

    through air. Other elephants receive the messages through the sensitiveskin on their feet and trunks. It is believed that this is how potential mates

    and social groups communicate.

    ReproductionMating Season: Mostly during the rainy season.Gestation: 22 months.

    Litter size: 1 calf (twins rare).Calves weigh between 200-250 lbs at birth.At birth, a calf's trunk has no muscle tone, therefore it will suckle through

    its mouth.

    PET

    Apet (orcompanion animal) is ananimal kept primarily for a person's

    company or protection, as opposed toworking animals,sport animals,

    livestock, andlaboratory animals, which are kept primarily for performance,

    agricultural value, or research. The most popular pets are noted for their

    attractive appearances and their loyal or playful personalities.

    Pets commonly provide their owners (or guardians) physical and emotional

    benefits. Walking adog can supply both the human and pet with exercise,

    fresh air, and social interaction. Pets can give companionship to elderly adults

    who do not have adequate social interaction with other people. There is a

    medically approved class oftherapy animals, mostly dogs, that are brought to

    visit confined humans. Pet therapy utilizes trained animals and handlers to

    achieve specific physical, social, cognitive, and emotional goals with patients.

    The most popular pets are likely dogs andcats, but people also keephouse

    rabbits,ferrets;rodents such asgerbils,hamsters,chinchillas,fancy rats, and

    guinea pigs;avian pets, such ascanaries, parakeets, andparrots; reptile pets,

    such asturtles,lizards andsnakes;aquatic pets, such astropical fish and

    frogs; andarthropod pets, such astarantulas andhermit crabs.

    Some scholars andanimal rights organizations have raised concern over pet-

    keeping with regards to the autonomy ofnonhuman animals.

    3ne of *frica4s most famous etinct animals, the 5uagga was a subspecies of the

     plains zebra, which was once found in great numbers in 2outh *frica4s +ape rovince

    and the southern part of the 3range Free 2tate. It was distinguished from other zebras

     by having the usual vivid mar's on the front part of the body only. In the mid-section,

    the stripes faded and the dar', inter-stripe spaces became wider, and the hind5uarters

    were a plain brown. The name comes from a 6hoi'hoi word for zebra and is

    onomatopoeic, being said to resemble the 5uagga4s call.

    The 5uagga was originally classified as an individual species, 75uus 5uagga, in #%.

    3ver the net fifty years or so, many other zebras were described by naturalists and
