My favorite animal is the Arctic fox it has very small ears because with big ears very much heat is lost so the small ears cause the fox to lose less heat.
Mangrove is a coastal ecosystem that occurs in the transition between land and sea in tropical and subtropical regions of the world, occupying environments flooded by tides such as estuaries, coastal lagoons, bays and deltas. These environments are not necessarily characterized by the mixture between fresh and salt water. The plants that make up the mangrove and dominate the landscape of this ecosystem are the mangroves.
There are adaptations that promote mangrove plants to survive in this very different place and they are: air roots so that they can breathe and exchange oxygen, because de soil has a less quantite about oxygen; there are glandules in its leaves to eliminate the large amount of salts and it is called halophytes; the seeds still germinate attached to the mother plant and are released at a stage of development called the propagule. The propagules accumulate a large amount of nutritional reserves, which allows their survival until they find a suitable place for their fixation.
These are some adaptations that we have on a mangrove ecosystem and it's an important ecosystem that there are so many species like crabs, fishes and a wide variety of animals and food for other animals. But unfortunately this paradise is disappearing and being destroyed by man.
