The Top Five Extreme Mammals  

by rockfingrz Photography

Write-up by Azi A

Animals like Mammals or formally recognized as Mammalian is a class of vertebrate animals. Its name is derived from their distinctive feature, the mammary glands, with which they feed their young. Living mammal’s species can be identified by the presence of sweat glands, which includes those that are specialized to produce milk. Mammals have practically the very same distinguishing features and characteristics to humans. They are recognized as the warm-blooded animals, covered with hair and we like to think of ourselves as the greatest mammal around due to the fact humans have all the advantages by means of our intellectual mind. Even so, in several categories other animals have us beat, paws down. The following are the top list of class mammalian:

The Largest

Blue Whale is a massive creature that survives on plankton. Weighing 150 tons, the blue whale is the largest animal recognized living creature. Their capability to maintain life on such a grand scale is aided by its oceanic way of life. Their vegetarian eating habit supports them to live a huge life-form.

The Smallest

Kitti’s Hog-nose bat or Bumblebee bat really earns its title since it is only measuring 1.14-1.3 inches and weighing .06-.07 ounces. Although the smallest land mammal, the pygmy shrew is only slightly bigger, tilting the scales at a heft .05-.09 ounces. They are so modest that they’re outweighed by two standard paperclips. Even though their diminutive stature places them eye to eye with numerous snails and insects, these two smallest animals are true warm-blooded vertebrates: they can produce milk and they are covered with hair.

The Fastest

As may possibly be expected, the mammal in this category depends on the terrain. And because they are living on different type of lifestyle mammals every domain needs diverse kinds of locomotion skills.

The known fastest air mammal is the big brown bat, which can flap its way up to 15.5 miles per hour. While the fastest water mammal is the killer whale that can reaches a substantially higher 34 miles per hour. And of course we cannot forget the land creature which is the titled as the overall fastest mammal, the cheetah. It can run as quickly as 70 miles per hour and due to the remarkable amount energy they want, this mammal can pour on their power only for a short period of time but a small period is enough for them to regained strength for yet another run.

The Slowest

In a competition over slowness, there are three animals come to our mind: the tortoise, the sloth, and the snail. Definitely the snail is the slowest of them all. The garden snail clocks in at a molasses-like .03 miles per hour. Not because of their size and weight but by moving at a steady pace, it would take the snail 12.5 hours to go around a standard city block.

The Thickest

And lastly, this category titled to the rhinoceros, the land mammal with the thickest skin of any animal. It has 1-inch-thick skin and rough boss.Mammals are the closest living creature to humans, and they are called extremes simply because of their distinctive features. Like Humans they also will need to survive living in this earth.

The biggest creature that has ever lived, the blue whale, is a mammal. So too are tiny pygmy shrews, giant pandas and human beings. Mammals are an amazingly varied group but they are all warm-blooded vertebrates. They have a bony skeleton and hair on their bodies at some stage of their lives. All mammals feed their young on milk from their own bodies and adult females have mammary glands for producing this milk. Mammals are usually agreed to be the most intelligent of all animals and they have the most extremely developed nervous systems. Most mammals have four limbs, but in some these have become adapted into flippers for swimming power (seals and whales) or even wings (bats). There are about 4600 species of mammal. Most live on land, but whales, dolphins, seals and sea lions are among those that have turn into adapted to life in water. Bats wings are created of skin stretched over a flexible bone structure like the human hand, so they can control their direction extremely effortlessly. This makes them professional fliers and they invest a lot of the time in the air. Mammals are generally divided into three groups—monotremes (egg-laying mammals), marsupials (pouched mammals) and placental mammals. The placental group is by far the largest.

Fastest Swimming Mammal

The fastest swimming mammal is the Killer Whale, it is also known by the name Orcinus Orca. Did you know that the Killer Whale is not in fact a type of whale? This Orcinus Orca is really the largest type of dolphin that exists. In general, animals which are this big cannot move extremely quickly. However, the Killer Whale can travel up to 34 miles per hour. If you are working in the metric system, you will know that the Killer Whales travel at 55.5 kilometers per hour.

Now that we know that the Killer Whale is the fastest swimming mammal in the world, now let us look at what the significance of such a statement is. Why does it matter that the Killer Whale is the fastest swimming mammal on the planet? Having this unique attribute allows the creature to have some adaptations that really help it.

Because this mammal can swim so quickly, it is one of the fastest predators in the ocean. Therefore, other sea creatures had better beware! They are able to catch seals, sea lions, and whales, which help to keep them nourished and full.

Now that we have told you what the absolute fastest swimming mammal in the ocean is, why don’t we look at some of the other creatures of the sea and how fast they swim. You will notice that the size of the mammal has a huge effect on how quickly they are able to go.

Although the Killer Whales are fast, they are much slower than the fastest fish in the sea. These fish are as follows and they travel at the following speeds:

  • Sailfish (68 miles per hour)
  • Marlin (50 miles per hour)
  • Wahoo (48 miles per hour)
  • Tunny (46 miles per hour)
  • Bluefish tuna (44 miles per hour)
  • Great blue shark (43 miles per hour)
  • Bonefish (40 miles per hour)
  • Swordfish (40 miles per hour)
  • Four winged flying fish (35 miles per hour)
  • Tarpon (35 miles per hour)
