AFRICAN WILD DOG


4/24

The African Wild Dog (Lycaon pictus) is a

carnivorous mammal of the Candia family,

found only in Africa, especially in scrub

savanna and other lightly wooded areas. It

is also called the Painted Hunting Dog,

African Hunting Dog, the Cape Hunting Dog,

the Spotted Dog. The scientific name "Lycaon pictus" is

derived from the Greek for "wolf" and the

Latin for "painted".


5/24

Adults typically weigh 17-36 kilograms (37-79

pounds).A tall, lean animal, it stands about 30

inches (75 cm) at the shoulder, with a head and

body length averaging about 40 inches

.Animals in southern Africa are generally larger

than those in eastern or western Africa.

The African Wild Dog is endangered by humanoverpopulation habitat loss and hunting. It uses

very large territories and it is strongly affected

by competition with larger carnivores that relyon the Hyena. Lions often will kill as many wild

dogs but do not eat them.

BLACK RHINO


7/24

The Black Rhinoceros (Diceros bicornis), alsocolloquially Black Rhino, is a species of

rhinoceros, native to the eastern and central

areas of Africa including Kenya, Tanzania,

Cameroon, South Africa, Namibia, and

Zimbabwe. Although the Rhino is referred to as

black, it is actually more of a grey/brown/white

color in appearance. The World ConservationUnion (IUCN) has declared West African Black

Rhinoceros, as extinct. About 3600 Black

Rhinoceros exist in the world.


8/24

An adult Black Rhinoceros stands 140170 cm (5567 in) high at the shoulder

and is 3.33.6 m (1112 ft) in length. Anadult weighs from 800 to 1,364 kg (1,800to 3,000 lb). The females are smaller thanthe males. Two horns on the skull are 50

cm long and can grow up to 140 cm. The Black Rhinoceros has been pushed to

the brink of extinction by illegal poaching

for their horn and by loss of habitat. Thehorn is used in traditional Chinesemedicine, coma patients, cure fever .

LEOPARD


10/24

The leopard ( Panthera pardus) is thesmallest of the four "big cats" in the genus

Panthera; the other three being the tiger,lion and jaguar.

The leopard has relatively short legs and a

long body, with a large skull. It is similar inappearance to the jaguar, although it is ofsmaller and slighter build. Its fur is markedwith rosettes that are similar to those of

the jaguar, though the loepards rosettesare smaller and more closely packed.Leopards that are melanistic, that is eithercompletely black or very dark, are known

as black panthers.


11/24

Leopards live mainly in grasslands,

woodlands and riverside forests. The

animal has primarily been studied in opensavannah habitats, which may have

biased common descriptions. It is

generally considered nocturnal, forinstance, but radio-tracking and scat

analysis in West Africa has found that

rainforest leopards are more likely to be

diurnal and crepuscular.

NORTH AMERICA

GIANT KANGAROO RAT

WOOD BISON

HUMPBACK WHALE


13/24

GIANT KANGAROO RAT


14/24

The giant kangaroo rat is one of over 20 species

of kangaroo rats, Head and body length

averages between 12 to 14.8 inches. The tailmeasures between 6.3 to 7.5 inches in length

and ends with a tuft of hair on the tip. A giant

kangaroo rat can leap over 6 feet in a single

jump.

Giant kangaroo rats are found on dry, sandy

grasslands. Diet consists of seeds, leaves,

stems, and buds of young plants. The giantkangaroo rat is only found in one area of less

than five square miles between the Carrizo Plain

and the city of Taft, located in west-central

California where it is legally protected.


15/24

Like many other rodent species, the giant

kangaroo rat is threatened by habitat loss

to agricultural development. Conservationefforts for this species include attempts to

find additional land for habitat in the Kern

and San Luis Obispo counties of

California, and monitoring of its current

population, distribution, and remaining

habitat.

WOOD BISON


17/24

Scientific Name: Bison athabascae. The wood

bison is a subspecies of the North American

Bison and is only found in Canada. It differs fromthe other North American subspecies (the Plains

bison) in many ways. The wood bison can weigh

over 1950 lb making it the largest mammal in

North America. Both the male and female haveshort black horns, but the female's horns are

straight and the male horns curve slightly inward.

Males are larger than females and can reach

12.5 feet in length and around 5.9 feet in height.


18/24

Bison are social animals and can be found

in small herds year-round. In the summer,

bison can be found in small willowpastures and uplands where they feed on

willows and grass. In the fall, they can be

found in the forest where they feed onlichens. Females give birth to two calves

usually within a span of three years. The

calves remain dependent on the mother

for seven months.

HUMPBACK WHALE


21/24

The head of a humpback whale is broad and

rounded when viewed from above, but slim in

profile. It is quite round, narrowing to a slender

peduncle (tail stock). The top of the head and

lower jaw have rounded, bump-like knobs, each

containing at least one stiff hair. The purpose of

these hairs is not known, though they may allowthe whale to detect movement in nearby waters.

There are between 20-50 ventral grooves which

extend slightly beyond the navel.

Adult males measure 40-48 feet (12.2-14.6 m),adult females measure 45-50 feet (13.7-15.2 m).

They weigh 25 to 40 tons (22,680-36,287 kg).


22/24

Humpback whales feed on krill, small shrimp-like

crustaceans, and various kinds of small fish.Each whale eats up to 1 and 1/2 tons (1,361 kg)

of food a day.

Found in all the world's oceans, most

populations of humpback whales follow a regularmigration route, summering in temperate and

polar waters for feeding, and wintering in tropical

waters for mating and calving. In the Arabian

Sea, a year-round non-migratory population ofhumpbacks appears not to follow this general

rule.


23/24

Their feeding, mating, and calving grounds

are close to shore and because they are

slow swimmers, the humpback whaleswere an easy target for early whalers. The

International Whaling Commission (IWC)

gave them worldwide protection status in1966, but there were large illegal kills by

the Soviets until the 1970's. It is believed

they number about 30,000-40,000 at

present, or about 30-35% of the originalpopulation.
