Why do scallops swim

The majority of farmed scallops are from China. Scallops eat by filtering small organisms such as krill, algae, and larvae from the water they inhabit. As water enters the scallop, mucus traps plankton in the water, and then cilia move the food into the scallop's mouth. Unlike other bivalves such as mussels and clams, most scallops are free-swimming. They swim by clapping their shells quickly using their highly developed adductor muscle, forcing a jet of water past the shell hinge, propelling the scallop forward.

They're surprisingly speedy. Scallops swim by opening and closing their shells using their powerful adductor muscle. This muscle is the round, fleshy "scallop" that anyone who eats seafood will instantly recognize. The adductor muscle varies in color from white to beige. The Atlantic sea scallop's adductor muscle may be as big as 2 inches in diameter.

Many scallops are hermaphrodites , which means that they have both male and female sex organs. Others are only male or female. Scallops reproduce by spawning, which is when organisms release eggs and sperm into the water.

Once an egg is fertilized, the young scallop is planktonic before settling to the sea floor, attaching to an object with byssal threads. Most scallop species lose this byssus as they grow and become free-swimming. There are hundreds of species of scallops; in general, they are not endangered. Scallops are marine bivalve mollusks of the family Pectinidae; the best-known are species of the genus Pecten.

Scallop species vary in their habitats; while some prefer coastal areas and intertidal zones, others live deep under the ocean. All scallops are bivalves, and in most species, the two valves of the shell are fan-shaped. The two valves may be ribbed or smooth or even knobbed.

Scallop shells vary radically in color; some are white while others are purple, orange, red, or yellow. Scallop shells are easily recognized and have been a symbol since ancient times. The fan-shaped shells have deep ridges, and two angular protrusions called auricles, one on either side of the shell's hinge. Scallop shells range in color from drab and gray to vivid and multihued. Scallop shells are an emblem of St. James, who was a fisherman in Galilea before becoming an apostle. James is said to be buried at Santiago de Compostela in Spain, which became a shrine and pilgrimage site.

Scallop shells mark the road to Santiago, and pilgrims often wear or carry scallop shells. The scallop shell is also the corporate symbol for the petrochemical giant Royal Dutch Shell.

Other marine robots have been made which emulate the locomotion of fish , manta rays , sea snakes and other forms of swimming.

And now we have a clam! Let me know when I can buy one to play with in my pool. Dan Killam! Hou continue to create and amaze us all!!

Hilarious videos and informative at the same tume. Like Like. You continue to publish, create, and amaze us all!! The videos of the swimming clams are hilarious and informative at the same time.

They can see, but not super well. Scallops have up to eyes which respond to the light and dark around them and therefore, moving objects so they can manoeuvre around other objects when swimming.

The ocean is a very noisy place There are lots of fish known to communicate through stridulation or the process of making sounds using body parts. Fish have sonic muscles near their swim bladders or tendons in the pectoral fin which they use to communicate with others. Some fish rub or clack together their pharyngeal teeth that lie in the back of their throat or even pop their jaws to make noise.

There are all kinds of clicks, grunts, pops, whistles, purrs, groans, growls, barks, hums and hoots that go on in the ocean! Research is still being carried out to determine why fish make noises. Some experts believe fish make sounds to signal to other fish their location during group feeding. There is still a lot to learn.
