Horses live without a gall bladder. Lots of animals, including our beloved cats and dogs, dont have sweat glands on their bodies. Lungless salamanders live happily without you guessed it lungs. And lots of snake species have only one working lung. So, as you have probably guessed, we've prepared another compilation of cool facts about animals. Did you know that some animals don't have really important organs?
And perhaps the most impossible creature in the world is a jellyfish. It doesnt have any sensory organs were used to, like eyes, ears, and nose, it has no skeleton, but most importantly, it hasnt got a brain or heart. Its body is almost entirely made of water thats why, if you take a jellyfish out of the sea and put it on the shore, it will soon melt. It just might be that jellyfish have given up their hearts and brains for the sake of other sea creatures, because octopuses, for example, can have multiple of those! Date: 2022-04-19
