right610Why are Otters strong swimmers? Many people are fascinated by otters because they are elusive creatures who are able to swim through the rivers and in the sea with great strength, speed and elegance. They are often spotted near savannah or low land forest areas where they enjoy hunting for food; however, they will swim swiftly away as soon as they start to feel the presence of humans. Many people have wondered how otters became such strong swimmers – is this skill due to their body shapes or is it something that they have mastered over time?One reason is that they are able to hold their breathe is because an otter’s lung capacity is 2.5 times greater than that of similar-sized land mammals.?However, sea otters have been known to stay submerged for more than 5 minutes at a time. River otters, however, can hold their breath for up to 8 minutes. As a result, the increased time underwater improves otters’ opportunity to sense prey and forage for food. Furthermore, otters possess great strength in their arms and speed in their tails so that they are able to escape the many dangers present in the oceans and rivers. In addition, otters are extremely strong due to the fact that they have many muscles within their tails. These muscles have evolved over time because their bodies have needed to adapt to the extreme conditions in the oceans and rivers. This means they can achieve speeds of more than 14 kilometers per hour.As well as the fast speeds at which they swim, otters have developed great strength in their arms. When swimming at speed, they use a front crawl arm action; however, when they are in calmer waters, they often prefer breast stroke. They are able to use a variety of strokes due to the flexibility in their shoulders and wrists.These are the reasons why otters are such strong swimmers and able to survive for long periods of time in the deep oceans and rivers.Key:The title is a question that is answered in the textWritten in the present tenseWritten in a formal tone Information organised in logical paragraphsUse of precise wordsANSWERS:right610Why are Otters strong swimmers?
