Jellyfish


Medusa Jellyfish are the major non-polyp form of individuals of the phylum Cnidaria. They are typified as free-swimming marine animals consisting of a gelatinous umbrella-shaped bell and trailing tentacles. The bell can pulsate for locomotion, while stinging tentacles can be used to capture prey.
Jellyfish are found in every ocean, from the surface to the deep sea. A few jellyfish inhabit freshwater. Large, often colorful, jellyfish are common in coastal zones worldwide. Jellyfish have roamed the seas for at least 500 million years,^[1] and possibly 700 million years or more, making them the oldest multi-organ animal.^[2]

 

Musk Ox

The musk ox live in the frozen tundra of northern, Alaska, Canada, Ellesmere Island, Greenland, Norway, Sweden and Siberia. No other hoofed animal lives as far north as the musk ox. The musk ox can live in the harsh conditions of the arctic tundra because its 24" long hair and woolly undercoat ward off frost andprovide insulation. It has a sturdy build. It looks like a huge dust mop on hooves, their long hair

reaching almost to the ground. Its muzzle is usually white. It can weigh from 396-880 pounds, and reach a length of 7 feet. The musk ox gets its name from the odor produced by glands beneath the bull's eyes. The male has thick horns that almost meet on top of its head in what is called a "boss". The horns curve down besides its face and out at the ends. The female has smaller horns, without a boss. Instead the top of her head is covered with whitish hair.

In the summer the musk ox herd has about 10 members. They will use the almost constant daylight to stuff themselves on plants. They need to put on enough fat to get them through the long winter. In winter the herd can have about 15 to 20 members. They will head out to higher ground where the fierce Arctic winds blow the snow off the ground. Here they will feed on crowberry, bearberry, and willow. The herd only travels about 50 miles between its summer and winter feeding areas.

Breeding season starts in July and goes on until the end of August. Each herd has a dominant male, or bull, who will try to keep other bulls from mating with the females. The female will give birth to one calf the following April through June. The calf can graze in about a week but keeps suckling for another year. The lifespan of a musk ox is about 24 years.

Muskoxen coexisted with the mastodons and mammoths and have survived early hunters and climate changes that caused the extinction of other species. The musk ox doesn't have many predators. Polar bears can sometimes kill weak or injured oxen. The Arctic wolf is the only serious predator.

Musk ox form a defensive formation when threatened. They will first run to a higher location, then turn and stand shoulder-to-shoulder in a circle. With their heads lowered, they form an impenetrable wall. The young are protected in the center of the circle. Musk oxen stampede easily and sometimes young calves become separated from the herd and are lost.

The musk ox's defense is useless against bullets, and they became easy targets for humans. They were almost hunted to extinction for their fur and their meat. By the early 20th century the population had become depleted. In 1917 the Canadian government gave them protection and now there are about 90,000 musk ox in that country.

More ominous as far as the decline of the musk ox is concerned are the effects global warming has had on their breeding. In the past few years, as a result of warmer climates, the coastal plains used as calving grounds have had more snow, and as a result, a later thaw. Musk oxen have moved to the foothills to find forage and often give birth there, making them and their calves more vulnerable to grizzly bears.

The Inpiaq speaking Eskimos of the Northern Slope of Alaska call the musk ox "Oomingmak", which means "animal with skin like a beard".

Vampire bat

Vampire bats are bats whose food source is blood, a dietary trait called hematophagy. Three bat species feed solely on blood: thecommon vampire bat (Desmodus rotundus), the hairy-legged vampire bat (Diphylla ecaudata), and the white-winged vampire bat(Diaemus youngi). All three species are native to the New World, ranging from Mexico to Brazil, Chile, and Argentina.

Pteropus

Bats of the genus Pteropus, belonging to the megabat suborder, Megachiroptera, are the largest bats in the world. They are commonly known as the fruit bats or flying foxes among other colloquial names. They live in the tropics and subtropics of Asia (including the Indian subcontinent), Australia, islands off East Africa (but not mainland Africa), and a number of remote oceanic islands in both the Indian and Pacific Oceans.^[1] There are at least 60 extant species in this genus.^[2]

The oldest ancestors of the genus Pteropus to be unearthed appear in the fossil record almost exactly as they are today, the only notable differences being early flight adaptations such as a tail for stabilizing. The oldest megachiropteran is dated at around 35 million years ago, but the preceding gap in the fossil record makes their true lineage unknown.

Characteristically, all species of flying foxes only feed on nectar, blossom, pollen, and fruit, which explains their limited tropical distribution. They do not possess echolocation, a feature which helps the other sub-order of bats, the microbats, locate and catch prey such as insects in mid-air. Instead, smell and eyesight are very well-developed in flying foxes. Feeding ranges can reach up to 40 miles. When it locates food, the flying fox "crashes" into foliage and grabs for it. It may also attempt to catch hold of a branch with its hind feet, then swing upside down – once attached and hanging, the fox draws food to its mouth with one of its hind feet or with the clawed thumbs at the top of its wings.

dog

The domestic dog (Canis lupus familiaris),^[2][3] is a subspecies of the gray wolf (Canis lupus), a member of the Canidae family of the mammalian order Carnivora. The term "domestic dog" is generally used for both domesticated and feral varieties. The dog may have been the first animal to be domesticated, and has been the most widely kept working, hunting, and pet in human history. The word "dog" may also mean the male of a canine species,^[4] as opposed to the word "bitch" for the female of the species.

The present lineage of dogs was domesticated from gray wolves about 15,000 years ago.^[5] Though remains of domesticated dogs have been found in Siberia and Belgium from about 33,000 years ago, none of those lineages seem to have survived the Last Glacial Maximum. Although mDNA testing suggests an evolutionary split between dogs and wolves around 100,000 years ago, no specimens prior to 33,000 years ago are clearly morphologically domesticated dog.^[6][7][8]

Dogs' value to early human hunter-gatherers led to them quickly becoming ubiquitous across world cultures. Dogs perform many roles for people, such as hunting, herding, pulling loads, protection, assisting police and military, companionship, and, more recently, aiding handicapped individuals. This impact on human society has given them the nickname "Man's Best Friend" in the Western world. In some cultures, dogs are also source of meat.^[9][10] In 2001, there were estimated to be 400 million dogs in the world.^[11]

Most breeds of dogs are at most a few hundred years old, having been artificially selected for particular morphologies andbehaviors by people for specific functional roles. Through this selective breeding, the dog has developed into hundreds of variedbreeds, and shows more behavioral and morphological variation than any other land mammal.^[12] For example, height measured to the withers ranges from 6 inches (150 mm) in the Chihuahua to about 2.5 feet (0.76 m) in the Irish Wolfhound; color varies from white through grays (usually called "blue") to black, and browns from light (tan) to dark ("red" or "chocolate") in a wide variation of patterns; coats can be short or long, coarse-haired to wool-like, straight, curly, or smooth.^[13] It is common for most breeds toshed this coat.

Cat

the domestic cat^[1][2] (Felis catus^[2] or Felis silvestris catus^[4]) is a small, usually furry, domesticated, carnivorous mammal. It is often called the housecat when kept as an indoor pet,^[6] or simply the cat when there is no need to distinguish it from other felidsand felines. Cats are valued by humans for companionship and ability to hunt vermin and household pests. A group of cats is known as either a "Glaring" or "Clowder" of cats.

Cats are similar in anatomy to the other felids, with strong, flexible bodies, quick reflexes, sharp retractable claws, and teeth adapted to killing small prey. Cat senses fit a crepuscular and predatory ecological niche. Cats can hear sounds too faint or too high in frequency for human ears, such as those made by mice and other small game. They can see in near darkness. Like most mammals, cats have poorer color vision and a better sense of smell than humans.

Despite being solitary hunters, cats are a social species, and cat communication includes the use of a variety of vocalizations(meowing, purring, trilling, hissing, growling and grunting) as well as pheromones and types of cat-specific body language.^[7]

Cats have a rapid breeding rate. Under controlled breeding, they can be bred and shown as registered pedigree pets, a hobby known as cat fancy. Failure to control the breeding of pet cats by spaying and neutering, and the abandonment of former household pets, has resulted in large numbers of feral cats worldwide, with a population of up to 60 million of these animals in the United States alone, while in Japan they are caught and disposed of.^[8]

Since cats were cult animals in ancient Egypt, they were commonly believed to have been domesticated there,^[9] but there may have been instances of domestication as early as the Neolithic.^[10]

A genetic study in 2007 revealed that all domestic cats are descended from as few as five female African wildcats (Felis silvestris lybica) c. 8000 BCE, in the Middle East.^[9][11] Cats are the most popular pet in the world, and now found almost everywhere where people live.^[12]

SEJARAH AWAL Idea penubuhan sekolah Methodist ini telah dirancang pada tahun 1935, Pada tahun 1936 SMK(L)Methodist Sentul telah lahir dan pengasas pertamanya ialah Rev, p, L. Peach, Beliau adalah merupakan seorang Pengetua Pendakwah Arneriko dalam bidang pendidikan yang mosyhur, Pada awal penubuhannya sekolah ini tidak mempunyai bangunan, kakitangan dan hanya sedikit sahaja pelolor. Kelas yang pertama bermula pada lOhb, Februari 1936 iaitu dibelakang Gereja Methodist Tamil di Sentul. Hanya terdapat 7 orang pelajar dan gurunya dipinjamkan dari SMK(L) Methodist KL loltu. Mr, William Dudley. ZAMAN PRA-PEPERANGAN SMK(L) Methodist Sentul telah dibuka secara rasminya pada 27hb, April 1939 oleh Hen, lvlr, S.W. Jones iaitu Residen British untuk negeri Selangor, Batu asas telah diletakkan pada tahun 1938, Pada tahun 1939 sekolah ini telah mempunyai 7 buah bilik darjah, sebuah pejabat dan sebuah dewan yang mana bang un an ini dikenali sebagai Blok Menara. ZAMAN PERANG Di zaman ini. sekolah ini mengalami banyak perubahan. Pada tahun 1940, Tentera Diraja Australia telah mengambilalih bangunan sekolah ini dan sekoah ini terpaksa berjalan pada sesi petang di SMK Convent Sentul. Semasa pemerintahan Jepun, Kerajaan Jepun telah memberikan kebenaran kepada Tentera India untuk menggunakan bangunan ini untuk tujuan pendidikan, walaub­agaimanapun bahasa Jepun juga diajar disini pada ketika itu. ZAMAN SELEPAS PERANG Selepas perang berakhir, Mr, W, Dudley telah diarahkan oleh Jabatan Pelajaran untuk membuka semula sekolah ini. Pada masa itu terdapat banyak permintaan untuk menempatkan anak-anak di sekolah ini termasuklah pel ajar yang lebih usia untuk memasuki alam persekolohon. Bagi mengatasi masalah ini sekolah terpaksa mengadakan dua sesi persekolahan untuk menampung seramai 100 orang pel ajar, Dalam pada menghadapi berbagai masalah, sekolah ini telah berjaya menerbitkan majalah sekolah yang pertama dan diberi nama "The Sentinel" semasa pentadbiran pengetua, Rev, J.A. P Oswald.Permintaan yang banyak untuk bersekolah di sini juga telah menyebabkan keperluan untuk membesarkan lagi bcnounon. Pada permulaannya, bangunan sementara iaitu bangsal telah dibina, Kelas khas Melayu juga telah dlmulokcn, Pada tahun 1951,2 buah bilik darjah dan sebuah makmal sains telah ditambah di Blok Menara, Pada tahun 1955, bangunan 3 tingkat yang menempatkan 12 buah bilik dorjoh. sebuah pelobot. sebuah perpustakaan dan bengkel telah dlolno, Pada masa ltu. jumlah pelajar telah meningkat ke 1000 orang.Pada tahun 1957, Persatuan Murid-murid Tua (Old Boys' Association (OBA)) telah dltubuhkcn Perubahan lain ialah memperkenalkan mata pelajaran Sains Tulin dan Matematik Tambahan pada tahun 1958. Pada tahun yang somo. sekolah menengah dan sekolah rendah telah dipisahkan di bawah pentadbiran yang berlainan termasuklah Ahli Lembaga Pengelolanya.Pada tahun 1961, sekolah telah merayakan perayaan Jubli Perak Pada masa ini sekolah telah mendapat tambahan 4 buah bilik darjah dan sebuah lagi makmal solns, Sebuah kantin juga telah dibina untuk menampung keperluan pelajar dari sekolah rendah dan menengah. BIDANG AKADEMIK MBS, Sentul started as a "feeder" school to MBS, K,L but in 1954, IT presented IT first batch of Cambridge Certificate candidates who sat for the examination in St. John's Institution. This batch of students did very well. Academically, the school has produced a long list of outstanding students - too long to name all of them. Rhodes scholar, Prof, Ratnalingam, engineer Mr, Chan Weng Chiu, Prof. Dr, Ashoka Menon, chief pilot Haasan Ahmad, lawyer Y,Bhj Tan Sri Vadiveloo and banker Y.Bhj Tan Sri Azman Hashim are among the many doctors, lawyers, businessmen" teachers, Govemment officers and other successful people who had made their Alma Mater proud by their achivements and their contributions to society, to the nation and to the school. THE EXTRA-CURRICULAR FIELD The school was also not lagging behind in the extra-curricular field. The school won the coveted Bastion Shield for the History Quiz: organized by The UniversITy of Malaya for two years running, that is, 1972 and 1973, Famous names like cricketeer R,Banerji, who played for the Malaysian Cricket Association in H,K in 1974, athlete Gopinathan who was first in the Selangor AAA Cross Country and karate exponent P,Thiagu who won the gold in the under-16AP junior karate championship all come from MBS, Sentul. In 1993, the soccer team gave V,I a trashing to become the under-18 K,L schools champion. Recently too, the school has been doing well in Hockey, Sepak Takraw and Chess. We were the individual events champions and took third place in the overall category in the recent interschool chess toumament. THE OBA Credit should also be given to the OBA which was mainly founded the students of MBS, Sentul. One of their achievements has been the setting up of several scholarships and awards namely the Peach scholarship, the Chan Weng Chiu Foundation Scholarship, the AG, Lee Medal, Mr, Kwong See Khoon Geography Book Award and the K,G Zachariah Book Award. The OBA has also generou:'ly contributed towards the School Development Fund and has always been ready to help the school.
