The Crab


Crabs are fascinating creatures with their striking colour of deep orange. I feel I want to shine their shell. I remember searching for them at the sea side and delighted when I found one.  But there is a lot of knowledge about them. The crab belongs to a group called the crustaceans, named for their crusty coatings on their bodies.  There are a variety of crabs including the Hermit crab which protect their bodies by living inside empty shells of seasnails.  Crabs are decapods meaning they have ten legs.  The first legs are strong pincers for tearing food.  Crabs use for spotting pray have a pair of  antennae and a pair of eyes on stalks.  The amazing male fiddler crab has one large pincer which they wave to attract a mate.  The worlds largest land crustacean is the coconut crab. Its leg span measures upto one metre which helps to climb coconut trees to feed or escape predators. They are also known as robber crabs because they steal food when they can.  The largest crab is the Japanese crab with a legspan of 4 metres. 

Crabs want to live in  oceans or fresh water and on land particulary in tropical regions.  The crab reproduces by the female fertilizing their eggs on their pleopods.  They like to attract a mate by pheromones, visual, acoustic and vibratory means. They want to mate belly by belly.  They wanto release their hatched larvae into the ocean.  Crabs walk sideways to their destination called crab wise.  Some are capable of swimming.  They communicate using their pincers by drumming and waving.  They want to eat algae.  Also eat molluscs, worms, crustaceans fungi bacteria and detritis.  Crabs work together to provide food , protection for their family and find a comfortable spot for the female to release her eggs.

The crab has  obstacles on its journey. They have predators such as birds carrying them up and dropping them on rocks to remove the shell before eating. Fish with shell eating jaws will attack them. Seals and Raccoons will have the crab for dinner.  The crab is known used for crab meat.  The crab is caught farmed at fisheries and eaten worldwide. They are also harvested tearing off their claws and putting them back in the water to regenerate making it a sustainable industry. They are then used in cookery.  They feel pain when often boiled alive according to scientists.

The crab has evolved and a sturdy robust structure. They are land and water breathing.  It has a super family  of four thousand five hundred different species.  The crab is depicted as a constellation Cancer.  it has been worshipped by ancient Peru.  It has also appeared in stories such as karkinos and just so stories.  What a popular creature.  Long live the crab.You can find crabs in England along the beaches. Crabbing 1-2 hours before high tide all the way through 1-2 hours after high tide the water will have a good movement and you have a better chance of catching a crab.  They do pinch so a cage is needed. There are 56 species of crab in the British isles.

Nuitritional facts of crabs.  Crab meat is a popular and versatile type of seafood. It is also very healthy and a good addition to a balanced diet, as it contains many nutrients coupled with a low fat content.

Crabs are crustaceans, most usually found in the ocean, that are eaten in many countries around the world. They are used in many different dishes, including bisque, curry and crab cakes, as well as cooked whole, steamed, boiled, baked or fried. Some species, such as soft shelled crabs, are eaten whole (generally after molting). Crab is considered a delicacy in many countries and is often substituted with cheaper imitation crab meat, which may contain a small amount of real crab meat, but is mostly made from artificially flavored fish.

The health benefits.  Crab is an excellent addition to a healthy eating plan. It is low in calories with only around 85-90 per 100g (depending on crab type). It does contain some fat, but it is generally unsaturated fat which is considered heart healthy. Crab is also a natural source of omega-3 fatty acids, which can help to improve memory, decrease the chances of having a heart attack, decrease risk of cancer, and possibly help to improve depression and anxiety.

Crab is a low risk seafood for mercury. Many fish, particularly at the higher end of the food chain, contain dangerous amounts of mercury and are not recommended as frequently eaten foods. Crab contains many of the benefits of other seafood, but without the risk of mercury poisoning.

Crab is also a good source of vitamins A, C and the B vitamins including B12, and minerals like zinc and copper. It is a source of selenium, which may be a means of preventing cancer. Crab also has some chromium, which is considered a useful mineral if you have insulin resistance, as it may improve blood sugar metabolism.

Cautions About Crab

If you have an allergy to crab meat you should be careful not to eat it or dishes that may contain crab. If you are allergic to crab, you may also be allergic to other types of shellfish, including lobster and prawns. The symptoms of a crab allergy can be as minor as a skin rash or as dangerous as anaphylaxis, which can lead to death if not treated promptly. Crab also contains moderately large amounts of purines, which are necessary for the healthy functioning of the body, but in some individuals can cause gout.

Crab may also easily cause food poisoning if it is not treated and prepared correctly. Crab must be fresh, without a strong odor and should be kept cold or frozen if it is not eaten immediately.
