Hi Steemit family!

Life in the sea is tastier, for those who live on the shore of the beach or live nearby know what I mean and good for those who have the opportunity to visit the coast know that living on the beach is one of the best experiences in life, there is an atmosphere of immensity when you look at the horizon and the days are more pleasant, and for the animal that I present today must also be, it is a crab considered as the largest of land and has a somewhat strange work loves coconuts so its name the coconut crab. Accompany me to discover this incredible creature.

Belongs to the family of arthropods this means that is intimately related to spiders some insects, scorpions, and varieties of crabs that are in the same family order, his closest relative is the hermit crab and its dimensions place it as the largest crab that lives on land.

Its habitat is scattered in several localities and beaches around the world where there is tropical climate, but in the place where it has been best preserved is in the Christmas Islands and Seychelles, the climate and particularities of these two islands may be the most appropriate for the development of this beautiful specimen.

Its most striking feature is its enormous size, can reach half a meter in diameter including their legs and can weigh up to 5 kilograms, its appearance is too bulky to go unnoticed, its front legs could scare away even the most fierce predator that approached him, his legs can exert a pressure that can be bought with the bite of a dog, imagine the tweezers can have a crushing force of 3500 Newtons, this is very positive for the crab as it can hold objects of an average weight of 30 Newtons, this is very positive for the crab as it can hold objects of an average weight of 30 kilos, its front legs could scare away even the most fierce predator that approached it, its legs can exert a pressure that can be bought with the bite of a dog, imagine the tweezers can have a crushing force of 3500 Newtons, this is very positive for the crab as it can hold objects of an average weight of 30 Newtons.

Although in their adult stage they can frighten anyone in their initial stage of life they are small larvae that do not cease to be very different from their other relatives, in this stage, they are floating in the ocean.

The change arises when they come to the surface, here the metamorphosis begins developing a gill lung which allows them to be on the surface, this organ which is the product of evolutionary modifications once it is developed prevents the crab from diving back into the ocean because it loses its gill capacity to breathe underwater which means that if this happens the crab could run the risk of dying.

source

Its development is slow, reach maturity at 6 years of age and can live up to 40 years, although they are famous for opening coconuts to eat their fruit, these invertebrates not only eat this tropical fruit, in addition to coconuts can eat all kinds of leaves, insects, even mammals or anything that is in composition, this characteristic of being almost scavenger is because on many of the islands where it sometimes lives food is scarce and this forced the crab coconut to eat other things to survive.

source

Returning to how it is possible that they can open the coconuts, well it does not stop being as different as the humans open it, the crabs locate with precision the place where the fruit germinates, here are 3 points, is the weakest part where the crab uses its tweezers to penetrate the coconut and to be able to break it to obtain the pulp of coconut, this prowess they realize thanks to thousands of years of evolution where I remain engraved in its DNA as to open the coconut after thousands of failed attempts. Interesting, isn't it?

It's thought that Coconut Crabs may have been involved in the demise of the aviator Amelia Earhart. Imagine being marooned on an island alone and having to fight off swarms of these things while trying to sleep...
