Often processed using a variety of seasonings, ranging from sweet-sour, oyster sauce, and many more. Scallops do have a delicious and appetizing taste. But do you know how fast can a clam run and what are the benefits of clam for the body?
Shells are mollusks which have soft bodied meaning, a types of which are a fan of the UK population, because of their delicacy. processed in the form of chowder is a soup that is thick and soft, full of flavor and texture.
What are shellfish?
The word “shellfish” can be a very vague term. Usually, this term refers to a type of animal called “mollusk shells”, although the term shellfish can include, all, some, or only some species of this type of animal.
As a result, the word “clams” does not have much meaning in biology, although it is often used more specifically for cooking. In general, the term “clams” is used to describe all types of shell mollusks capable of digging into sand or other types of sediment.
This helps distinguish from other mollusks that can more directly stick to the surface (which oysters and shellfish can do).
Where’s the shell habitat?
The living habitat of shellfish is in the sea with strong currents that make it have to stick to an object so as not to drift.
How do shellfish move so fast?
Shells can move from one area to another due to water currents, apart from digging for sand. On the other hand, shellfish don’t have much control over how or where the water currents carry them.
Why do shellfish fire water?
First, the shell relaxes its muscles, which causes the shell to open. … Surviving in the sand, the shell pushes its fleshy legs down. Then he squeezes water into the bottom of his leg, causing his frills to bulge. So anchored, shellfish contracted.
How do shellfish move?
Shellfish have the most control over their movements using their feet. This leg allows some lateral (side-to-side) movements. However, these legs are most useful for allowing shellfish to dig into the sand.
For this reason, the legs are most powerful in digging, which allows the shell to sink itself safely so that it is harmless.
In addition to digging sand, most shellfish then move around with water currents, allowing them to move from one area to another. On the other hand, shellfish don’t have much control over how or where the water currents carry them.
What muscles do shellfish use?
Most shellfish have two different types of muscles. The most basic ones they have to help them open and close their shells through their “valve” muscles.
Very strong muscles can allow some shellfish to live in water and survive briefly out of water. Another muscle that shells have is a muscular “leg”.
The legs are controlled by two muscles, the anterior and posterior leg muscles, which work together to control the legs. Shellfish are unique in that they have attractive muscles that allow greater leg control.
How fast can a clam run
Anyone who has ever tried to pluck razor shells from a sandy beach knows that they can dig quickly. This edible animal can bury itself at a rate of about one centimeter per second, and they get inside. A hand-length shell can make burrows up to 70 centimeters down.
Perhaps this animal is only widely known as a delicious portion of food and is widely sold in roadside food stalls. Did you know How Fast Can a Squid Run? Read more in the article.
Common Features of Shellfish
All shells have a pair of shells that usually mirror symmetry connected to a ligament. In most shells, two adductor muscles regulate the opening of the shell.
Shellfish have no head (nor brain) and the only simping that has eye organs owned are kidneys, heart, mouth, and anus. Shells can move with a “foot” in the form of a flat organ removed from the shell at any time or by opening the shell in a shock.
The open circulatory system means that it does not have blood vessels the oxygen supply comes from highly liquid blood rich in nutrients and the oxygen that envelops its organs is plankton by filtering. Shellfish themselves are prey for squid and sharks.
Shellfish have substances that are good for humans
A substance that resembles glue on shellfish is called byssus. This substance is thought to be able to make the animal strong attached to various types of objects in the sea.
The uniqueness of byssus was researched by scientists and resulted in the discovery that byssus including a type of protein can be used to reconstruct damaged human body tissues.
Phillip Messersmith a professor of biomedical engineering at Northwestern University said “Shellfish have a role in tissue reconstruction in the human body it is useful to repair the membranes of a ruptured premature fetus or premature birth and other serious complications”. This includes repairing abnormal cells that cause cancer to return to its original state.
Classification of bivalves by Linnaeus (1758):
- Kingdom: Animalia
- Phylum: Mollusca
- Class: Bivalvia
- Subclass: Heterodonta
- Infraclass : Euheterodonta
- Order: Veneroida
- Superfamily: Cardioidea
- Family: Cardiidae
- Subfamily: Fraginae
- Genus: Frum
- Species: Fragum unedo
Morphology of Bivalvia
The bivalve class includes shellfish – the shells of the body are bilaterally symmetrical protected by a hard limestone shell. The shell part consists of the dorsal part and the ventral part on the dorsal part is:
- Joint teeth as shafts when valves open and close as well as straighten both valves
- The joint ligament serves to unite the dorsal part valve and separate the valve next to the vertal.
- Umbo protrusions of the shell in the dorsal part.
The shell consists of three layers, namely the order from the outside to the inside as follows:
- Periostrakum is a thin and dark layer composed of horn substances produced by the edges of the mantle so it is often called the horn layer its function to protect the layer that is on the inside and this layer is useful to protect the shell from carbonic acid in water as well as give the shell color.
- The prismatic middle layer is thick and consists of prism-shaped crystals of calcium carbonate derived from organic matter produced by the edges of the mantle.
- Makes is the deepest layer composed of fine crystals of calcium carbonate is a pearl layer produced by the entire surface of the mantle. In this layer, there is more organic matter than in the prismatic layer. This layer looks shimmering and is found in oysters/mother-of-pearl if exposed to light can spread the diversity of colors. This layer is often referred to as the pearl coating.
Benefits of Shellfish
Maintaining Heart Health
The high content of omega-3 fatty acids in shellfish can lower the levels of triglycerides that are too high.
People who often experience anemia need to consume foods rich in iron. Well, shellfish is one of them. Eating shellfish rich in iron can help increase hemoglobin in the blood.
Maintaining Nervous System Function
The human body needs vitamin B12 which plays an important role in helping the nervous system to function properly.
Boosting Immunity and Metabolism
Shellfish contain very high levels of animal protein and also its essential amino acid content is almost 100 percent.
Well, protein is one of the important nutrients that are useful to keep the body to perform its functions properly, including in maintaining endurance and metabolism.
