Animals And Water: Some Curious Data

Water is a substance without which life on the planet would not exist. Both people, plants and animals need water to live and the eventual deprivation of this for a prolonged period of time causes death. Planet earth is the only one in the solar system that has water in all three states, solid, liquid and gaseous, and is therefore the only one where life is possible. Below we will tell you some curious details about the  relationship between animals and water.

1. There are 525 million cubic kilometers of water on earth  . This amount has neither increased nor decreased in the last two thousand million years.
2. 90% of the freshwater resources available on the planet are found in the South Pole.
3. Fresh water is only 0.01% of the total water on the planet.
4. Elephants are excellent swimmers and can run up to 40km / h. On the other hand, they are the only animals in the world that cannot jump.
5. The Australian koala never drinks water, in fact it gets the amount of water it needs from that present in the eucalyptus leaves, which are very rich in it.
6. The females of the hippocampus (the seahorse) lay their eggs inside the male. Delivery takes place six weeks after gestation, which can last up to two days.
7. Goats never drink water on the go.
8. Camels can survive up to 10 days without drinking water. But when they have it available, they can drink up to 106 liters at one time.
9. Sailfish are the fastest fish in the world. It can reach 110 km / h on short stretches.
10. Dolphins sleep with their eyes open.
11. The blue whale’s tongue weighs as much as an adult elephant.
12. Marine fish can feel thirsty.
13. Whales sleep as they swim slowly.
14. There are fish in the abyssal depths capable of generating their own light (as can be seen in the movie “Finding Nemo”). These fish in fact use these natural luminescences to attract, and therefore be able to devour, their prey.
15. The most poisonous animal in the world is a type of jellyfish called a “sea wasp”, also known as Cubomedusa or box jellyfish. Its venom can kill a human in 45 seconds.
16. Whales sing and their songs can last for months. These songs are composed of continuous and monotonous sounds, very characteristic of these animals.
17. The dwarf shark does not exceed 25 cm in length.
18. The blue whale is  the animal that has the largest size on the face of the earth. It can measure up to 30m in length and can weigh up to 180 tons.
19. The whale shark is the largest fish that exists. It can measure up to 12 meters in length and can weigh up to 12 tons (no, the whale is not a fish).
20. Freshwater animals are dying out 5 times faster than terrestrial ones.
21. It takes 450 liters of water to produce just one chicken egg.
22. Water is the main regulator of the terrestrial temperature.
    
23. Fish are the most numerous animal category among vertebrates. In fact, there are over 24 thousand known species. 40% of these fish species are freshwater.
24. The scientific name of the sunfish is  mola mola  (in Spanish  mola is a common expression that is used to define something you like). This fish can weigh up to 2 tons and can reach 3 meters in length. However, when he is born he is  60 million times smaller than his parents.
25. The vast majority of fish possess a swim bladder which  allows them to control the depth of their location. To dive, the bladder contracts and decreases in volume, causing the fish to weigh more than water (having freed itself of air and making it denser). To re-emerge instead, the bladder fills with gas, through a mechanism of the fish that allows them to produce these gases. In this way their total density decreases and they move towards the surface.
26. The electric eel can emit electrical discharges of up to 600 volts per millisecond.
27. One of the most peculiar forms of hunting in nature is that of the archer fish. This type of fish shoots a small amount of water at the insects that rest on the leaves near the water. When the insect falls, the fish devour it. Its aim  is quite accurate and can hit objects up to 90cm away, although young fish are much less adept at shooting than more experienced ones.
