White Shrimp (Litopenaeus setiferus- probably) postlarva


A penaeid shrimp- most likely the White Shrimp (Litopenaeus setiferus) postlarva

Collected: North Inlet, Georgetown, SC. Summer 2015.Notes:Notes: This photo shows a living specimen of one of the three commercial penaeid shrimps occurring olong the Atlantic Coast. Adult white shrimp are typically found in the coastal ocean or embayments. Postlarvae are often found in salt marsh creeks and may enter lower salinities.ID Notes: The late stages of the three commercial shrimp larvae are distinguished from other penaeids by having three pair of claws. See Below. The three shrimp species are difficult to distinguish. Consult  1Ditty, J. G., 2011.

Collected by Paul Kenny, Baruch Marine Lab, University of South Carolina.

Identified by Dennis Allen, Baruch Marine Lab, University of South Carolina as most likely the white shrimp based on season and location. There is a small possibility that it is a pink shrimp (Farfantepenaeus duorarum)postlarva.

Below: Arrows denote the short eye stalk (1) and 3 pair of pincers on the anterior appendages. These features are typical of all three species of commercial shrimp postlarvae.
