Killer Whale

Orcas, or killer whales, are the largest of the dolphins and one of the world's most powerful predators. They feast on marine mammals such as seals, sea lions, and even whales, employing teeth that can be four inches (ten centimeters) long. They are known to grab seals right off the ice. They also eat fish, squid, and seabirds.

Though they often frequent cold, coastal waters, orcas can be found from the polar regions to the Equator.
Killer whales hunt in deadly pods, family groups of up to 40 individuals. There appear to be both resident and transient pod populations of killer whales. These different groups may prey on different animals and use different techniques to catch them. Resident pods tend to prefer fish, while transient pods target marine mammals. All pods use effective, cooperative hunting techniques that some liken to the behavior of wolf packs.

Whales make a wide variety of communicative sounds, and each pod has distinctive noises that its members will recognize even at a distance. They use echolocation to communicate and hunt, making sounds that travel underwater until they encounter objects, then bounce back, revealing their location, size, and shape.

Killer whales are protective of their young, and other adolescent females often assist the mother in caring for them. Mothers give birth every three to ten years, after a 17-month pregnancy.
Orcas are immediately recognizable by their distinctive black-and-white coloring and are the intelligent, trainable stars of many aquarium shows. Killer whales have never been extensively    hunted by humans.

Hippopotamus

Hippopotamus

Hippopotamuses love water, which is why the Greeks named them the "river horse." Hippos spend up to 16 hours a day submerged in rivers and lakes to keep their massive bodies cool under the hot African sun. Hippos are graceful in water, good swimmers, and can hold their breath underwater for up to five minutes. However, they are often large enough to simply walk or stand on the lake floor, or lie in the shallows. Their eyes and nostrils are located high on their heads, which allows them to see and breathe while mostly submerged.

Hippos also bask on the shoreline and secrete an oily red substance, which gave rise to the myth that they sweat blood. The liquid is actually a skin moistener and sunblock that may also provide protection against germs.At sunset, hippopotamuses leave the water and travel overland to graze. They may travel 6 miles (10 kilometers) in a night, along single-file pathways, to consume some 80 pounds (35 kilograms) of grass. Considering their enormous size, a hippo's food intake is relatively low. If threatened on land hippos may run for the water—they can match a human's speed for short distances.

Hippo calves weigh nearly 100 pounds (45 kilograms) at birth and can suckle on land or underwater by closing their ears and nostrils. Each female has only one calf every two years. Soon after birth, mother and young join schools that provide some protection against crocodiles, lions, and hyenas.
Hippos once had a broader distribution but now live in eastern central and southern sub-Saharan Africa, where their populations are in decline.

Hippo Fun Facts 

Hippo is really a short name for Hippopotamus.

A group of hippos is called a school.

A hippo's lifespan in the wild is about 40 years.

A hippo's weight can be 5,000-8,000 pounds.

Since hippos love the water the Greeks named them the "river horse".

A baby hippo is called a calf.

Even though hippos love water and spend a lot of their time in it, they are very bad swimmers.

Chipmunk

Lively and speedy critters, chipmunks are smallest members of the squirrel family. Their pudgy cheeks, large, glossy eyes, stripes, and bushy tails have made them a favorite among animators, and landed them a series of starring roles in Hollywood.

Of the 25 species of chipmunks, all but one, Asia’s Tamias sibiricus, is found in North America. Ranging from Canada to Mexico, they are generally seen scampering through the undergrowth of a variety of environments from alpine forests to shrubby deserts. Some dig burrows to live in, complete with tunnels and chambers, while others make their  homes in nests, bushes, or logs.

Depending on species, chipmunks can be gray to reddish-brown in color with contrasting dark and light stripes on the sides of their face and across their back and tail. They range in size from the least chipmunk, which, at 7.2 to 8.5 inches (18.5 to 21.6 centimeters) and 1.1 to 1.8 ounces (32 to 50 grams), is the smallest chipmunk, to the Eastern chipmunk, which grows up to 11 inches (28 centimeters) and weighs as much as 4.4 ounces (125 grams).

Chipmunks generally gather food on the ground in areas with underbrush, rocks, and logs, where they can hide from predators like hawks, foxes, coyotes, weasels, and snakes. They feed on insects, nuts, berries, seeds, fruit, and grain which they stuff into their generous cheek pouches and carry to their burrow or nest to store. Chipmunks hibernate, but instead of storing fat, they periodically dip into their cache of nuts and seeds throughout the winter.

Their shrill, repeated, birdlike chirp is usually made upon sensing a threat but is also thought to be used as a mating call by females. Chipmunks are solitary creatures and normally ignore one another except during the spring, when mating takes place. After a 30-day gestation, a litter of two to eight is born. The young stay with their parents for two months before they begin to gather their own provisions for the winter ahead.

For the most part, chipmunks, although susceptible to forest fragmentation, are not currently threatened. However, the Palmer’s chipmunk (Tamias palmeri) is considered a vulnerable species.

Honeybee

Honeybee hives have long provided humans with honey and beeswax. Such commercial uses have spawned a large beekeeping industry, though many species still occur in the wild.All honeybees are social and cooperative insects. A hive's inhabitants are generally divided into three types.Workers are the only bees that most people ever see. These bees are females that are not sexually developed. Workers forage for food (pollen and nectar from flowers), build and protect the hive, clean, circulate air by beating their wings, and perform many other societal functions.

        The queen's job is simple—laying the eggs that will spawn the hive's next generation of bees. There is usually only a single queen in a hive. If the queen dies, workers will create a new queen by feeding one of the worker females a special diet of a food called "royal jelly." This elixir enables the worker to develop into a fertile queen. Queens also regulate the hive's activities by producing chemicals that guide the behavior of the other bees.Male bees are called drones—the third class of honeybee. Several hundred drones live in each hive during the spring and summer, but they are expelled for the winter months when the hive goes into a lean survival mode. Bees live on stored honey and pollen all winter, and cluster into a ball to conserve warmth. Larvae are fed from the stores during this season and, by spring, the hive is swarming with a new generation of bees.

Cockroach - Super Pest Survivalist

           Cockroaches have inhabited the earth for more than 250 million years. There are over 4,000 kinds with only 30 being the kind to be near human dwellings. There are American ones, Asian (perhaps the most destructive), German, Surinamian, Peruvian, and Madagascar Hissing Cockroaches... Brown Cockroaches, Wingless Cockroaches... and they are all coming to eat your Cheerios and Cornflakes because they love your cereal even more than you do. More money is spent to control cockroaches in the United States than any other pest. They are the number one urban pest throughout the world.

                The average roach-infested household contains more than 20,000 roaches.Roaches can live up to 20 days without food and 14 days without water.They can flatten their bodies and crawl through a crack thinner than a dime.Cockroaches can survive radiation up to 12 time greater than humans.Cockroaches are startled by the smallest of air movements and can run for cover in less than .05 seconds.        

          

Among the dirt and filth
Roaches may transmit a wide variety of diseases and cause common allergic reactions previously thought to be caused by dust. They have been implicated in the spread of tuberculosis, leprosy, cholera, dysentery and typhoid. However, they are not considered to be disease vectors, that is they do not actively transmit any virus or bacteria. If they come out of the sewer for example, they may carry pathogens on their bodies and passively transmit those pathogens by close contact. They frequently enter buildings by coming up through drains.

True Survivors
Cockroaches will eat anything - food, leather, hair, and the glue in book bindings. They can live off the toothpaste residue in your toothbrush. They are cannibals and take a particular liking to each others' excrement. In extreme cases roaches will feed off people.

The Emperor Penguins

Emperors are the largest of all penguins—an average bird stands some 45 inches (115 centimeters) tall. These flightless animals live on the Antarctic ice and in the frigid surrounding waters.

Penguins employ physiological adaptations and cooperative behaviors in order to deal with an incredibly harsh environment, where wind chills can reach -76°F (-60°C).

They huddle together to escape wind and conserve warmth. Individuals take turns moving to the group's protected and relatively toasty interior. Once a penguin has warmed a bit it will move to the perimeter of the group so that others can enjoy protection from the icy elements.

Emperor penguins spend the long winter on the open ice—and even breed during this harsh season. Females lay a single egg and then promptly leave it behind. They undertake an extended hunting trip that lasts some two months! Depending on the extent of the ice pack, females may need to travel some 50 miles (80 kilometers) just to reach the open ocean, where they will feed on fish, squid, and krill. At sea, emperor penguins can dive to 1,850 feet (565 meters)—deeper than any other bird—and stay under for more than 20 minutes.

Male emperors keep the newly laid eggs warm, but they do not sit on them, as many other birds do. Males stand and protect their eggs from the elements by balancing them on their feet and covering them with feathered skin known as a brood pouch. During this two-month bout of babysitting the males eat nothing and are at the mercy of the Antarctic elements.

When female penguins return to the breeding site, they bring a belly full of food that they regurgitate for the newly hatched chicks. Meanwhile, their duty done, male emperors take to the sea in search of food for themselves.

Mothers care for their young chicks and protect them with the warmth of their own brood pouches. Outside of this warm cocoon, a chick could die in just a few minutes. In December, Antarctic summer, the pack ice begins to break up and open water appears near the breeding site, just as young emperor penguins are ready to swim and fish on their own.
