What are some extremes in the animal world?
In estimated 3-30 million animal species, this planet is teeming with biodiversity. Much of this diversity is represented by arthropods who have not yet been studied.
Of all the animals we know, the range of characteristics is impressive. But they are extremes in the world of animals that catch our imagination and force us to be more interested in life on our planet. This article will go through several of the most fascinating extremes in the animal world. The largest living animal - perhaps the largest that has ever lived - is a blue whale, one individual weighing by 190 tons (209 tons) with a length of 30 m (100 ft). Others were measured at a length of 33.3 m (110 ft), but were not weighed. As a result, the longest blue whale is about as long as a ten -storey building.Sist about hundreds of cells, including rotifers, gastrotrichs and the smallest images. These simple animals are so small that you can see their individual cells in the micro -photographic image. Of course, there are many unicellular organisms all around us, andLE Because they contain only one cell, they are not classified as animals that must be multicellular.
Among the phyla, which we would consider to be the best known, is one of the smallest animals parasitic wasps of the dikopomorfa echmeptterygis , measures only 0.139 mm in length, less than some amoeba. Its internal organs are firmly packed in the correct arrangement with barely any space left for the inner body cavity.
Another interesting extreme in the animal world is durability. This record is probably held by Tardigrada or "water bears", small segmented animals that are superficially resembling bears because of the fat bodies and small grasping of pendants. Tardigrady is one of the few animals capable of temporarily suspending their metabolism and going into a state called cryptobiosis. In this state, temperatures last as low as absolute zero, up to 151 ° C (303 ° F), 1,000 times more glowthan any other animal, more than ten years without water and pressures as low as a vacuum. Because of these properties, it is assumed that Tardigrady is the only animals that could survive exposed to space in space for a long time.
Another of the extremes in the animal world is not size, but length. Although the blue whale is the largest and most difficult animal, it is not the longest. This title holds the worm of bootlace, lineus longissimus , which was measured at 55 m (180 ft). These predators of invertebrates crawl along the ocean bottom and capture the prey of their proboscis. They are superficially resembling snakes.
