There are three different ways that shrimp move. While feeding on the ocean floor, shrimp use one set of legs known as periopods. However, these legs are fragile and are mostly used for perching. Shrimp also have five sets of another type of legs, which are called pleopods, and they are used for swimming. Finally, shrimp move backwards rapidly by using a movement called a tail snap.Know More
A shrimp's periopods are useful when they are feeding or moving short distances, but do not work well for longer distances. This means that shrimp are better suited for swimming than for walking. For swimming longer distances or for migrating, shrimp use their pleopods, which beat in unison and propel the shrimp through the water. Shirimp are able to swim 2 to 5 miles a day using these swimming legs.
The tail snap (or tail flex) technically moves the shrimp as well, but it is more defensive in nature.When a shrimp uses a tail flex, its abdominal muscles contract, which jerks the tail forward. The shrimp moves backwards through the water when the tail is snapped. In addition, this tail snap is used to propel the shrimp out of the water when necessary.Learn more in Marine Life
As of September 2014, the biggest shrimp ever caught was 18 inches long. It was caught in Florida waters near Fort Pierce by a fisherman named Steve Bargeron.

Shrimp are eaten by both Atlantic and Pacific cod, American herring, basking and whale sharks. They are also eaten by croakers, thornbacks, southern stingrays, southern flounders and Greenland halibut. Shrimp are eaten by people as well, who capture more than 3 million tons of the sea food each year.Full Answer >
Shrimp have been known to live from 1 year to as long as over 20 years in captivity. According to the Northeast Fisheries Science Center, the life cycle varies based on geography and the species of shrimp.Full Answer >
Like most crustaceans, shrimps are omnivores and consume both plant materials and small animals. They are not picky eaters and are considered as scavengers, ingesting anything that is small enough for them to eat, including decaying matter, mud, plankton, small fish and leftover food.Full Answer >
