A lot of confusion surrounds the scope of the term shrimp. Part of the confusion originates with the association of smallness.
Dendrobranchiata is a suborder of decapods, commonly known as prawns.There are 540 extant species in seven families, and a fossil record extending back to the Devonian.They differ from related animals, such as Caridea and Stenopodidea, by the branching form of the gills and by the fact that they do not brood their eggs, but release them directly into the water.
A little grebe (Tachybaptus ruficollis) running along the surface of the water as it flaps its wings in order to get the lift it needs to fly Grebes are small to medium-large in size ranging from the least grebe ( Tachybaptus dominicus ), at 120 g (4.2 oz) and 23.5 cm (9.3 in), to the great grebe ( Podiceps major ), at 1.7 kg (3.7 lb) and 71 cm ...

A shrimp (pl.: shrimp or shrimps ()) is a crustacean (a form of shellfish) with an elongated body and a primarily swimming mode of locomotion – typically belonging to the Caridea or Dendrobranchiata of the order Decapoda, although some crustaceans outside of this order are also referred to as "shrimp".
Like other Macrobrachium species, the Ohio shrimp is amphidromous. The larvae must live in saltwater and move to fresh water as adults. This is accomplished by having the larvae drift, free-floating, down the river until they reach water where the salinity is high enough to support them. Females carrying eggs may also migrate downstream before ...
The sea trout feeds mainly on fish, small crabs, shrimps and prawns. It is an anadromous , migratory fish , which closely resembles the Atlantic salmon in its form and lifestyle. In the sea, it makes long journeys and also swims upstream into small rivers in order to spawn.
