    Essay on Polar bear: The polar bear is a species of bear, lives in the Arctic Circle. Evidence from DNA analysis confirms that polar bears evolved from grizzly bears. Their body is covered with white fur so they are called “white bears”. Polar bears have a layer of fat or blubber that is 4 inches thick which helps keep their bodies warm while swimming in cold water.

    Introduction

    The polar bear is a species of bear, lives in the Arctic Circle. "Ursus maritimus" is the scientific name of this largest extant bear species which means "sea bear". In “The Inuit language”, the polar bear is called "nanook", and Historically, they are known as the "white bear".

    Description and Behavior of Polar Bear

    Polar bears have small heads, long necks, short ears, broad and black noses, brown eyes, and short tails. Their body is covered with two layers of thick white fur which turns yellow with age. Their fur is hollow and not really white. Each hair shaft is transparent because LYST and AIM1 that affect melanin production are absent.

    Polar bears have a layer of fat or blubber that is 4 inches thick which helps keep their bodies warm while swimming in cold water.

     Male polar bears also called boars are three times larger than female bears or sows. Male polar bears can grow 7 ft – 9 ft and weight will be 350–700 kg whereas females can grow 5 ft – 7 ft and weight will be 150–250 kg. There is no white pigment in the polar bear's coat. In fact, a polar bear has black skin and hollow hairs. Their legs are too large to distribute the load while walking on ice as well as to provide propulsion while swimming. Paw pads are covered with soft, small papillae, which provide traction on snow. 

    As polar bears are carnivorous, they use their 44 teeth to use for catching and tear food. 

    The strong pointed and curved claws of the polar bear are more than 5 cm long.

    Polar bears have an excellent sense of smell and hearing. They also have very good eyesight and good long-distance vision. They can locate their prey, such as seals, about 1 mile away and buried under 3 feet of snow. Since polar bears are excellent swimmers, they can swim at speeds of up to 10 km/h and can often swim for several days.

    In the wild, between November and February, female polar bears give birth to blind cubs, which are covered with fur, and weigh less than 0.9 kg.

     Polar bears rarely attack humans unless they are severely provoked. Hungry polar bears are extremely fearless and can attack, kill or eat humans.

    Polar bears prefer to live solitary lives. They produce many sounds and vocalisations such as chuffs, chuffs, huffs, moans, etc.

    In the wild, the lifespan of a polar bear is between 25 and 30 years.

    Diet of Polar Bear

    Polar bears are one of the top predators on the land. As polar bears are carnivorous, they eat meat. They prefer to eat ringed seals as well as harp seals, harbor seals, and hooded seals. They also eat birds' chicks and eggs and walrus too. Polar bears have been observed hunting beluga whales and narwhals also. During late summer and early fall, the sea is unfrozen so the Polar bears cannot hunt seals and may fast for several months. 

    Habitat of Polar Bear

    Polar bears are found in the north of the Arctic Circle to the North Pole and prefer to live in areas where sea ice meets water and spend several months at sea. The polar bears can be found in five countries including Russia, the U.S,  Greenland, Canada, and some of the northern islands, which are owned by Norway, such as Svalbard.

    Conclusion

    According to the World Wildlife Fund, polar bears play an important role in determining the health of the Arctic ecosystem.

    Polar bears lose their natural habitat due to global warming and climate change. Marine pollution, oil and gas development, and oil spills are the other threats to the polar bears and are listed as vulnerable species.

    Essay on Polar Bear 350 Words

    Polar bears are the marine mammals and the largest land carnivorous animals and the largest species of bear. Polar bears belong to the family Ursidae and the scientific name is “Ursus maritimus” which means"maritime bear". Evidence from DNA analysis confirms that polar bears evolved from grizzly bears.

    Polar bears can grow 7 to 8 feet and the length of their tails is 3 to 5cm long. Female polar bears weigh 150–250 kg and are smaller than males.

     Their body is covered with white fur so they are called “white bears”.Their fur is transparent, oily, and water repellent. In May or June, the polar bears shed their fur completely and replace it. They have small heads, two brown eyes, two small ears, large muscular legs, large paws, and curved and sharp claws. Their forelimbs are shorter than the hind limbs and their rounded forepaws are partially webbed. Although polar bears appear white, their skin is black in color.

    Since polar bears live in the Arctic, they are well adapted to their habitat. Designed to withstand cold temperatures, snow, ice, and open water, and for seal hunting, their physical characteristics are designed to protect them from the cold.

    Polar bears live in the Arctic Circle and spend most of their time swimming in the Arctic Ocean, and its surrounding seas.

    Polar bears are hypercarnivores and their diet consists of about 71% meat. Polar bears prefer to hunt and eat seals. They eat ringed seals, harp seals, hooded seals, and harbor seals. They also kill and eat walrus beluga whales and narwhals. Polar bears also eat different fish species like “Arctic charr” and “fourhorn sculpin”. 

    The female polar bear digs a maternity den, which has a narrow entrance and one to three chambers. From November to February, female polar bears give birth to two to three blind cubs.

    In 1972, the United States adopted the “Marine Mammal Protection Act” to protect the polar bear, which prohibits the harassing, hunting, capturing, or killing of all marine mammals. To protect polar bears, the “International Agreement on the Conservation of Polar Bears” was signed in 1973 by the five nations- Denmark, the United States, Norway, Russia, and Canada.

    Essay on Shark

    Essay on Shark: Sharks are one of the ancient species on Earth. Scientists believe that sharks existed more than 400 million years ago - long before the dinosaurs.  More than 500 shark species are found on the earth. River sharks are found in some rivers in Australia, South Asia as well as New Guinea. In Japan and Australia, sharks are common seafood.

    Introduction

    Sharks are one kind of fish, which fall into a subclass, called Elasmobranchii. Sharks are the top predators of the oceans. Scientists believe that sharks existed more than 400 million years ago - long before the dinosaurs. Until the 16th century, sailors called sharks "sea dogs”. More than 500 shark species are found on the earth. Different species of sharks have different sizes. The small dwarf lanternshark is only 17 cm in length, the smallest shark in the world. Whereas the world's largest shark is the whale shark, length is 40 feet to 55ft. The sharks who are at the top of the food chain or apex predators are the Great White Shark, Tiger Shark, Hammerhead Shark, Mako Shark, etc. 

    Description and Behavior of the Shark

    Sharks belong to a subclass Elasmobranchii. Their skeleton is not made of bones, but rather it is made of flexible and durable tissue called cartilage, which helps to reduce the weight of their skeleton. Sharks have no rib cages. Since there are over 500 species of sharks, they vary in size. Some species of sharks have spots or stripes on their skin such as Zebra sharks, Tiger sharks, which help them to camouflage. These markings also make it difficult for their prey to locate them.

    The tail fins of a shark, also known as the caudal fins. The top half of their tail fins are much longer than the lower half and this type of shape helps them to slow cruising and sudden bursts of speed or twist and turn. Shark’s eight fins are: two pectoral fins, two pelvic fins, a first and second dorsal fin, a caudal fin, and an anal fin which help them with swimming, steering, stability, thrust, lift, and propulsion as well as communiction.

    As all species of sharks are carnivorous, they have powerful jaws with sharp teeth. Different species of sharks eat different types of food so they have different types of teeth like needle-like teeth, dense flattened teeth, pointed lower with triangular upper, and non-functional teeth. Bull shark's jaws are in 7 series with 50 rows of teeth. Most sharks can have up to 300 teeth, but they lose at least one tooth every week, however, new teeth grow within a day. Some sharks lose 30,000 to 50,000 teeth in their lifetime.

    Shark liver is large and is full of oil. Their liver and cartilage help them swim. The shark's 5 to 7 gill slits are lined up on either side of their head. Spiracles are modified slits that play a vital role in respiration. When the shark moves, water passes through the mouth and gills in a process called "ram ventilation." Essay on Water Pollution

    Shark has a “J-shaped” stomach and a short-length intestine. They take a long time to digest their food. When unwanted items are unable to pass out of the stomach, the shark vomits to expel unwanted items from its mouth.

    Sharks have excellent eyesight which is about 10 times better than humans but they are color blind. Sharks have a layer of mirrored crystals, called tapetum lucidum which lie behind the retinas. This layer or tapetum lucidum helps them to see in turbid water and in very low light. Some species of sharks have a transparent or translucent third eyelid called the nictitating membrane, which helps them to protect their eyes as well as moisten them.

    Sharks have an excellent olfactory system and sense of smell which is absolutely necessary for their survival. They also have a very good sense of hearing and are able to hear prey from many miles away.

    Sharks have a swimming speed of about 8 km per hour, but their speed can reach over 19 km/h when attacking or feeding. 

    Different shark species have different lifespans. The Greenland shark can live 250 to 500 years whereas the Blue sharks live only 15 to 16 years.

    Diet of Shark

    As sharks are carnivorous, they consume large to small fish, marine mammals, squid, crustaceans,  shrimp, seals, turtles, octopus, dolphins, sea lions as well as plankton, etc. Sharks attack in packs when they hunt large prey such as dolphins. 

    Only four species of sharks such as Bull sharks, Great white sharks, Oceanic whitetip sharks, and Tiger sharks are dangerous to humans.

    Habitat of Shark

    Sharks live in seas and oceans but some species like the Bull shark and the River shark can live in seawater as well as freshwater. Sharks live at a depth of 7000 feet of seawater but some species may survive deeper. Sharks are found in the coral reefs where they get plenty of food such as crab, lobster, fish, etc. They are also found in sandy plains, estuaries, as well as shallow coastal water.

    Some species of sharks like Horn Shark, Catshark, etc can live in aquariums for a period of one year or more. 

    Conclusion

    Sharks are killed by the people for their meat and fins. In Japan and Australia, sharks are common seafood. In South India, baby sharks are cooked which is called “sora puttu”. Sharks are captured for their fins which are used for making “fin soup”. 

    Habitat loss, coastal development, pollution, shark culling, and many more are threats to sharks.

    The International Union for Conservation of Nature has listed 25 species of sharks as critically endangered.

    Governments of some countries introduced some laws to protect the sharks. In 1991, South Africa first declared the Great White Shark a legally protected species.

    Essay on Shark 250 Words

    Shark is a fish, lives in open oceans as well as freshwater. The earliest types of sharks are 450 million years ago, towards the end of the Ordovician era. Their body is not made of bones but of cartilage.

    Sharks have 5 pairs of gill slits behind their head which help them to filter oxygen from the water. More than 500 shark species are found on the earth. Sharks have numerous sharp teeth in their powerful jaws. They have a tooth replacement system through which sharks quickly replace shed teeth.

    Sharks prefer to eat fish, crab, plankton, turtle, dolphin, and other sea creatures. 

    Sharks are found in every sea or ocean but some species are kept in aquariums as captive such as zebra sharks, leopard sharks, etc.

    Sharks have excellent eyesight and hearing which helps them to catch their prey. 

     Sharks are apex predators or top predators so they play a crucial role in maintaining the ecosystem.

     The world’s largest Whale shark is about 60 feet in length and lives in Australia, South Africa, the Galapagos Islands, Belize, etc. The world's smallest shark, the Dwarf Lantern, is only 6 to 7 inches long and lives in the Caribbean Sea, the Hawaiian Islands, eastern Mexico, western Florida, etc.

    Currently, about 75 percent of shark species are threatened by poaching, capture, and hunting for their fins, skin, and meat. We need to put an end to such things and encourage others to do the same for this reason “Shark Awareness Day” is celebrated every year on 14th July.

Giant pandas belong to the Ursidae family and their scientific name is Ailuropoda melanoleuca.

    Giant pandas prefer to live alone and spend most of their life  roaming and eating. Giant pandas are active at dawn and dusk but they are also active at midnight. Giant pandas mark their territories by spraying urine or clawing trees. They produce different vocalizations to communicate. As the giant pandas climb the tree, they also take shelter on the hollow trees as well as in the rock crevices. When they are threatened, they can attack humans. 

    Female giant panda gives birth to two blind, toothless pink-colored cubs but she chooses only the strongest cubs to raise and the cub dies of starvation. The common predators of young and cubs of giant pandas are snow leopards and yellow-throated martens. The cubs are also attacked by eagles, black bears, and feral dogs, etc.

Their bushy tails help them to balance and flexible joints and strong claws help them to climb. They wrap their bushy tails around themselves to keep their bodies warm. They also have long wrist bones also known as “false thumbs” which help them to hold the bamboo while eating. Red pandas are nocturnal but they are also active in the twilight period. They sleep on the trees. Red pandas also prefer to live alone and mark their territory by feaces, spraying urine, or secretions from anal glands. Red panda produces seven different types of vocalization including hoot, bark, growl, etc. Mother red panda makes the nest in the hollow trees, logs, or crevices with twigs, grass, twigs, sticks, etc. Mother red panda gives birth to three to four blind but fully furred cubs. Red pandas can live 14 years in captivity. 

    Diet of Panda
