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".

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.

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.

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 .

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.

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.

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.

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.

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.

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).

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.

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.
