3. Wood Frog
Wooden frogs are a kind of Arctic creatures. They are always special in the Arctic region because they got the ability to freeze in a colder climate. In the winter season, the wood form freezes. And the surprising fact is that at that time their heart stops beating.
Then what happens? No worries, when the temperature rises in the region, they wake up from a frozen state and heart restarts. They feel fresh and new that time. It’s a mystery which lies behind this specific adaptation of wooden frog. The scientists are also much interested in this feature, and they are working hard to unlock the mystery.
Some organisms like bears slow down their hearts while hibernating. But the wooden frog is the only animal category as of today, which can stop the heart. The particular kind of solutes in the body of the frog stops the metallic activities during the frozen time. Also, it will allow the liquid in the body to solidify and prevent the organs from getting ᴅᴀᴍᴀɢᴇd.
It believes that the invention of the cause of this fact will make changes in the human heart transplantation process by making the heart to get frozen and transport the same. Thus the heart of wooden frog restarts and froze in cooler times.
Hummingbirds are the smallest of the bird’s family. They are native to America. These tiny birds measure 7.5 to 13 cm in length and weigh only 2.0 grams. They got this name from the humming sound created. It came from the beating sound of their wings.
The interesting fact of humming bird’s heart is that it can soar up to 1000 beats per minute. The birds can flap about fifteen times per second. The human eye will be able to see a blur only. The faster wing speed is offered by, the faster heart. Of these species, blue-throated hummingbird beats up to 21 beats per seconds. The efficiency helps these birds to bring enough oxygen to its muscles.
The top speeds of these birds are 15 meters per seconds. Some species can dive at a speed of 22 meters per seconds as well. The humming bird’s brain holds 4.2% of the total body weight. The second largest family of birds thus has numerous features about their tiny body. The average life span of these birds is about five years. Their supportive heart also makes it possible for them to fly at higher speeds. During migration, they can travel over 2000 miles twice a year.
