Scallop
* Some scallops live for ten years or more.
  * live in all of the world's oceans. They have a good reputation as a food source. As bivalves they have two shells. Shell collectors often collect the coloured fan-shaped shells.
* are a delicacy
  - able to move and swim through water by clapping their shells together
  - also unusual among bivalves in that their eyes are well developed
  - among the most delicate and delicious of all sea foods
  - at their best, plump, succulent and as white as the driven snow
  - easier to find when the sun is high overhead
  - filter feeders , and eat plankton
  - highly sensitive to shadows, vibrations, water movement, and chemical stimuli
  - long lived shellfish
  - low in fat and calories and an excellent source of protein
  - mollusks
  - natures divinity
  - part of scallops
  - popular in both Eastern and Western cooking
  - shellfishs
  - spoon-shaped hollows dissolved in limestone floors, walls, and ceilings
  - surface-dwelling bivalves that can swim by clappng together their valves
  - unusual among bivalves in that they are capable of jet-propelled swimming
* burrow into the sandy seafloor.
* can also be saut ed, grilled, boiled, poached, or breaded and fried.
* can clap their shells together to produce a jet of water that propels the animal forward
  - produce a sort of jet propulsion
  - propel themselves along the sea floor by flapping their shells
* can swim quite actively in a random fashion if disturbed
  - with brief bursts of speed by clapping their shells together
  - swim, but tend to remain in the same area throughout their lives
* eat microscopic food, like algae and plankton that floats through the water
  - tiny sea plants and food particles found floating around in the water
* feed by filtering plankton and detritus from the water
  - on plant and animal plankton
* generally live on sand bottoms.
* grow rapidly during the first several years of life
  - rather slowly and mainly in the spring and summer months
* have a central adductor muscle
  - characteristic and distinct odor that can be somewhat stronger than other seafood
  - distinct, sweet odor when they are fresh
  - one-year lifespan
  - shelf life of two to three days
  - sweetish odor with no excess liquid when bought in packages
  - dozens of eyes
  - shells that have distinctive ridges and are symmetrical
* lack a foot, and both oysters and giant clams lack a foot as adults.
* live in all of the world 's oceans.
* mostly stay in underwater grass beds on a soft, shallow sea floor.
* often contain sand when fishermen use dredges
  - occur in dense congregations known as scallop beds
* sit on top of the substrate, and are able to swim away from predators.
* swim by clapping their shells together.
* thus swim in short spurts.
* turn milky white and opaque in the center when cooked
  - white or opaque and become firm
* use a similar locomotion
  - water-jet propulsion to move through the water to escape predators such as starfish
* usually lie about on the floor of the ocean.
+ Adduction, Adduction in Scallops: Anatomy
  * Scallops have a central adductor muscle. It lets them open and close their shells. It is quite large and developed compared to other bivalves because they swim a lot.
+ Fishing dredge
  * Scallops often contain sand when fishermen use dredges. It can also damage the seabed if they use dredges carelessly. These days scallop dredging is sometimes replaced by scuba diving. However inventors are trying to invent a better dredge. Retrieved April 13, 2008.
+ Scallop, As food
  * Scallops are popular in both Eastern and Western cooking. They have two types of meat in one shell. The adductor muscle is white and meaty
  - Description: Bivalves
  * Scallops have a central adductor muscle. The inside of their shell has a scar in the middle. This shows where this muscle attaches to the shell. The adductor muscle of scallops is larger and more developed than the adductor muscle of oysters. This is because they swim a lot. Some fishermen and scientists think that scallops migrate
  - Food and digestion
  * Most scallops are filter feeders. They eat plankton. The plankton sometimes has scallop larvae in it. Siphons bring water over a filtering structure. Mucus then traps the food. Next, the cilia on the structure moves the food to the mouth
  - Life habits
  * Most scallops live freely. However, some species attach to a substrate by a structure called a byssus. When they contract the foot, they can go deeper into the sand. A free-living scallop swims by opening and closing its shell very fast. The scallop can defend itself in this way. It protects the scallop from threatening predators
