Survives underwater even without gills

There are tons of marine creatures that are amazing with their own qualities. Commonly, those who lives underwater knows of course how to swim and breathe even the presence of water around them. Unlike us humans, we should breathe air to live and if we will swim, we'll just hold it and go back to the surface before we lose it. Or we use devices to dive deeper than the water.

However, there are also marine creatures that are like humans. Do you think dolphins can breathe underwater?

All mammals, including dolphins, take in oxygen from the air. Dolphins retain their breath until they reach the surface, unlike fish, which breathe underwater through their gills. Dolphins are incredibly intelligent and agile creatures. Their breathing method is intuitive and can be changed according to the activities of the moment. Dolphins hold their breath as they swim down into the depths of the ocean in search of fish. The amount of time dolphins can hold their breath depends on a number of things. For example, bottlenose dolphins can stay underwater for up to 10 minutes.

So nope! Dolphins can't breathe underwater, they just utilized the air they breathe when they come into the surface. Hold it underwater then come to the surface to breathe air again.

Dolphins' overall circulatory system is absolutely astounding. While diving underwater, it can determine which functions are required and which can be temporarily suspended. This not only extends the time until they require air, but it also saves electricity. When dolphins dive deep, for example, they can turn off or slow the following systems:

  • Digestive system

  • Blood flow

  • Heart rate

This selective use allows a dolphin to swim or eat for as long as possible while underwater. Their heart and brain, as well as their tail muscles, may continue to work normally until it's time to come up for air. (Unfortunately, humans would suffer from decompression sickness as a result of the fast pressure changes.)

How do they Sleep?

These marine mammals sleep in one of two ways: they either lie calmly in the water, vertically or horizontally, or they sleep while swimming slowly with other species. A lot of similar behavior has been seen in zoos and aquariums. Individual dolphins also go into a deeper stage of slumber, which occurs primarily at night. Have you ever heard of logging? When dolphins sleep in this posture, they appear to be floating logs.

Whales is another marine animals that is a mammal and also unique in surviving underwater.

There are a lot of wonderful things in the world, because the Creator is true and powerful amongst all :>

Thank you for reading!
