10 animal species that don't drink water at all

Life without water, sound like a picture of the sandy desert with no sign of water drop anywhere far in the field of the desert. Humans cannot survive without water more than 3 days and we need to be hydrated for maintaining the heating our body but there live some strange 10 animal species who don’t need water for survival on earth and they can even live long without the necessity of water.

Life Science facts has made a list of 5 animal which does not drink water in its whole life

MEALWORMS

Mealworms start out life as an egg, then hatch into a larva, morph into a pupa, and finally emerge as a beetle. They have a modified urinary system called a “cryptonephridial” system, where the stars of their “kidneys” attach directly to the ends of their rectum. In other words, the last drops of moisture in their food is absorbed by the kidneys and returned to the middle of the gut. Thus they don’t excrete much moisture and can live entirely on their metabolically-produced water!

SAND GAZELLE

Sand gazelles live in a habitat of open sands and can survive long periods without needing water. They have truly adapted to such a harsh environment such as the Arabian Desert. Interestingly, sand gazelles have the ability to shrink their liver and heart – which in turn causes them to breathe and respire less often, thereby preventing extra moisture loss. Many people often assume the camel to be the epitome example of an animal that can go the longest without water, and while to some extent, they can. The ability of the camel to survive the desert environment pales when compared to the sand gazelle.” There are other unique ways this antelope of the sands conserve water, such as the way it can re-absorb some of its own urine back into its body.

FRESHWATER FISH

Only saltwater fish drink. In freshwater, the inside of the fish is “saltier” than the surrounding environment. Water moves into the fish by osmosis, passively, through the gills and the skin and the stomach. Fish have to eliminate all this excess water by peeing dilute urine. Lots of it. In saltwater, the environment is saltier, the fish loses water passively, so it has to drink. It eliminates excess salt using specialized cells; the excess salt is excreted primarily in highly concentrated urine.

FROGS DO NOT SWALLOW WATER

Frogs have very special skin! They don’t just wear it, they drink and breathe through it. Frogs don’t usually swallow water like we do. Instead, they absorb most of the moisture they need through their skin. Not only that, but frogs also rely on getting extra oxygen (in addition to what they get from their lungs) from the water by absorbing it through their skin. Because frogs get oxygen through their skin when it’s moist, they need to take care of their skin or they might suffocate. Sometimes you’ll find frogs that are slimy. This is because the frog skin secretes a mucus that helps keep it moist. Even with the slimy skin, these frogs need to stay near water. Toads, on the other hand, have tougher skin that doesn’t dry out as fast, so they can live farther from water than most frogs.

Tiger salamanders

Tiger salamanders do not drink water using their mouths. Rather they receive moisture and hydration from the water content of prey and from the environment through their semi-permeable skin. Skin absorption reinforces the need for a moist substrate at all times. Tap water contains chlorine and other chemicals that are harmful to most amphibians, including tiger salamanders. In light of this, use rain-water, purified bottled water, dechlorination to treat any tap water used in the habitat. Distilled water is not appropriate, as the minerals have been removed which can upset the osmotic balance of the salamander. Realise that adult tiger salamanders do not drink water, instead, they absorb it from the environment through their skin. If you are only keeping adult tiger salamanders, a water dish is unnecessary.
