The review of the blue planet by BBC
Our earth actually is a blue planet,which is covered with 71 percent of the world by brine.How vast such superficial content!Therefore,the mysterious field is composed of numerous parts,such as various marine animals and many different plants.This means a truth that we can鈥檛 neglect the effects alerted on the ocean by the creature and some terrestrial beings along the coast.
Food links,complex food net,describe relationship running through the animal-kinds,from plankton to the hugest sort,blue whale,approximately.To my surprise,blue whales,such a formidable giant,rely on millions of krill.Such gargantuan harvests depend on the continuing fertility of the ocean.There exists much amazing association between two species like this.Generally,grey whales are much bigger than killer whales.But 15 killer whales can trace an adult female grey whale several kilometers just for her baby.They chase the young until he can鈥檛 swim any longer because of toil.Whales breathe with lung,as is known.These killer whales try their best to press the baby grey whale to make his head in the sea.At last,the young whale dies of oxygen-poor.His mother can not do anything about it and continue her journey north for food,leaving the child鈥檚 body behind.She has no choice to give up the one who she had conceived for thirteen months.
Moreover,the living in the water is usually classified according to their ambient living environment.In the abyssal area,large ranks of transparent lives lead a rich and varied life.Among the group,imitation is a necessary skill to confuse the enemy and attain what they want.These guys may imitate the surroundings or just copy the color around them.Some fish have special luminous organs,which function as viewfinders,hiding in the dark.They reflect the weak blue light from water surface and slightly disappear along with it.Some striped mullets and jellyfish have the ability to flash like neon light.Their motion is excellent in disguise.Most of them move slowly relatively.As the depth rises,the quantity of living grow gradually with the sunlight brightening and energy strengthened.
In the shallow sea,battles happen every day almost.Various animals join in the cruel conflict.As is commonly seen,bands of sardines used to take action together for safety.It鈥檚 not,nevertheless,an ideal method.Bottlenose dolphin and whales unintentionally work in conjunction with each other.Dolphins are in charge of getting the sardines apart,making use of waves foam.Whales can enjoy the dish much more easily.Smart seabirds fly low,pressing close to the water,to find the best location to seize the prey.After that,they rush into the water like spurting arrow.The hunters grab their relish to the habitat.
Meantime,besides food link,there coexists symbiosis.Sea-gull and half-moon can help other fish by cleaning the mould on the cover.
What is vividly introduced above occurs in the diverse layers,while the layers are not alone,in touch with each other instead.Ocean current becomes the key factor to mix the brine from distinct areas.Nutrition blends to a new balance.Of course,this results in energetic fishing ground.Fish shuttle up and down,making water world filled with vitality and more oxygen dissolved.
The ocean is an organic whole in the long term,in spite of the pole and equator.Low degree represents a flinty challenge in the pole.Even an animal of large scale may face fatal attacks thanks to the jam resulting from the freezing cold weather.Near an ice hole lives a polar bear.Through the hole,white whales keep breathing during the past half year.The bear obtain some trophies by overwhelming these whales trapped in the hole.Harp seals give birth to their babies on the ice pieces,partly due to that reason.Coming to the next summer,generations fly back from the south.Guillemots nested on the cliff that bears and foxes are unable to reach.Fortunately,guillemots can haunt between sky and sea water.About on June,ice layer begin to melt.Many cracks emerge,which benefits the marine animals that need oxygen.Melting provide an access to cods for white whales.Autumn arrives,sea starts freezing again until November.On the opposite pole,situation precisely is on the contrary.Here dwell penguins.Surrounded by Antarctic Ocean,the continent gets rid of bears鈥 threatening,supplying penguins with solution to leisure.High temperature causes creature diversity,to some degree.In the tropic and sub-tropic,plants rank from algae to mangrove.The trait offers an important place for the beings to reside and frolic.Moon gravity plays a significant role in the forming of tide and tsunami.Coral reef improves the sea bed into a perfect harbor for different organism.Along with the rising tide,turtles land on some islands to lay eggs and crabs get out of the sand to search for animalcule to eat.Shellfish can come and go free.But it鈥檚 a tragedy that shellfish occasionally change into a delicious feast for others.Flounder,kite-shaped,always gets help from tide and wave and glides at pleasure.The strongest tide arrives after new moon,caused by sun gravity together with moon gravity.Sea bed expose in the air.Raccoons look for suitable food there,the best outcome is crab.At the same time,tide is the good timing for fishes to mate and accomplish fertilization and breeding.
But global changes now threaten the great blooms of plankton on which the whales depend.Once,and not so long ago,300,000 blue whales roamed the oceans.Now,less than 3% of that number remains.Our planet is still full of wonders.As we explore them,so we gain not only understanding,but power.It鈥檚 not just the future of the whale that today lies in our hands.It鈥檚 the survival of the natural world in all parts of the living planet.We can now destroy or we can cherish.The choice is ours.
