Crabs are considered one of the oldest animals in the world. Among its notable characteristics are those of being very adaptable to change.
For example, they are the animals that have adapted the most during history, both to inclement weather, climate changes, places, their own habitat, etc. They are animals that generally live in very rocky areas, on the shore of the beach and in rivers.
It depends on each species of crab, it is found in one area or another and more or less easily. For example, they are very difficult to collect, the crabs that are found in rocky areas, cliffs… they are very dangerous areas, the rocks slip a lot and there are few, the fishermen who try to catch crabs or people who do it without knowing the danger that they are exposed, they have slipped and not only have they hurt themselves, broken bones and made important injuries, but they have died.
Crabs are crustaceans. They are one of the most demanded crustaceans, for example, to eat. Lots of delicious dishes.
They are animals with a large shell. In fact, precisely the shell together with its legs (claws) is one of the characteristics of this animal. The shell helps the crabs to be safe or not defenseless against their predators. The shell for these animals is their bony shell.
As for their legs, they actually have five pairs. Neither more nor less (eye, they are not few either…) they have five pairs of legs and two of them are really like tweezers or pincers. Nor are they all. The two claws are for the crabs their weapons to be able to defend themselves from their predators, to defend themselves from them and at the same time to be able to hunt their prey and eat. Tongs/pliers are good weapons for them. In fact, they grab their prey, put great pressure on them and can crush, cut, rip… whatever they need with them.
As for the species of crabs, there are many and of many types. The difference is because of the color and its size. Crabs are not animals that like to be in groups, large groups, interact quite the opposite. They are a hermit species, they prefer to be alone and, in fact, that is why they are found in rocky areas that are difficult or very difficult to access.
Crabs, that is, crustaceans (which can also be called in this way and is the same), are from the decapod family. Therefore, as they are of this species, they have five pairs of legs and are also from the same family as others such as prawns, prawns, shrimp, etc.
Instructions
- Crabs eat fish and small animals that may perish and remain on the seashore.
- But also, because they must leave their habitat, they will look for other ways to feed and that is when they will survive by eating algae and debris that they can find in their nearby area.
- Some animals that they can find in the water and can eat it, will do so with the help of their pincers, which are very strong and will allow them to cut and dismember.
- The age of the crabs can be guessed and they are known a little more, they can be guessed by their shell. On average, a crab lives for many years, between fourteen and fifteen years.
- To guess the age only by the shell, it is known through its hardness.
- As for their mating, they do it according to the seasons of the year. In the case of crabs, it is in the fall. The male crabs are the ones that carry all the eggs of the young in their shell and do so all the time, until they end up becoming little crabs. In order to conquer the female and be able to mate, the crabs fight each other.
- The males fight by force, the one who has the most and wins, that one stays with the female.
- When they finish mating and the “zealous” season, they calmly retire to quiet areas.
What do you need:
- In their normal habitat, they will search for small fish.
- Algae.
- Some waste that they find in the nearby area (only when they do not find what to eat or are in an area that is not theirs and they have to resort to that).
- Dead animals.
- Smaller crustaceans.
Tips
In total there are thousands of species of crustaceans and not all of them are the same size. In fact, there are some species that are microscopic.
The crab, as we have already mentioned, when it comes to collecting them, they are always found on the seashore or in rocky areas, especially. They hold on to the rocks and even on the sand, they have pincers on two of their legs that you must be careful with, because if they grab you with them, they will do a lot of damage.
In general, they do not have a major problem when it comes to eating and if they are hungry; they will eat what is nearby or can be taken as food. From meat, fish, through fruits, dead animals… everything they catch and can eat.
These crustaceans must also be careful not to be the prey of other predators because indeed, they have many nearby.
Animals that is close to crabs, in the sea, on the beach, etc. Seals, even octopuses, birds… have to look for somewhat remote places to hide and have places to escape from their predators.
Not only will the crabs be in the sea, or among the rocks, they also want to be in the sand. Close to the beach, but with distance. For example, they can get to hide among some plants, in the sand itself, among the rocks, stones, among the algae… If they hide in the sand, they can get away at most, a few kilometers, but they will never go very far from the water, at most a few kilometers and less than ten.
It depends on the type and the species, there are those that are river crabs, those that are in the sea, many sizes… they are one of the crustaceans that cooks raffle the most for some succulent dishes or that are very tasty. Many are quite famous, such as crab soup.

The best known crabs around the world are two types: hermit crabs and coconut crabs (there are many more, but these are the most popular).
The hermit crab, they are usually living in the Atlantic Ocean, near the coast and in the Mediterranean Sea. If they cannot choose where they want to live, they will find life without problems because they adapt easily. But placed in their preferable comfort zone, they choose the muddy bottom and the puddles and these will be the areas where they can be seen the most, captured and caught by their predators as well. They will never be in the deep.
In contrast, the coconut crabs live in the areas of the Pacific Ocean and the Indian Ocean. The difference with the other species is that they have another type of color and also change their tone when they are mature and cannot swim. Unfortunately this species is in danger of extinction. They are close to such famous, peculiar and exotic islands as the Easter Islands and Cook Island.
