Xiphopenaeus kroyeri,commonly called theAtlantic seabob,is a commercially importantprawn.It is up to 140 mm (5.5 in) long and is the most intensely fished prawn species inthe Guianasand along much of theGulf Coast of the United States.
Description
[edit]Adults grow to 70–140 mm (2.8–5.5 in) long, with males only reaching 115 mm (4.5 in).[1]Therostrumhas five teeth near the base, but is smooth along the tip, which is greatly elongated and often curves upwards to varying degrees.[2]
Distribution and fishery
[edit]X. kroyerilives in the westernAtlantic OceanfromNorth CarolinatoSanta Catarina state,Brazil.[1]It is the most important commercial prawn in parts of theUnited StatesfromPensacola(in theFlorida Panhandle) toTexas,and inthe Guianas.In other areas, such asMexico,Nicaragua,Honduras,andTrinidad,the fishing effort is only locally intensive.[1]In 2000–2007, the annual catch was greater than 40,000 t (88,000,000 lb).[1]
Taxonomy
[edit]Xiphopenaeus kroyeriwasfirst describedbyCamill Hellerin 1862, under the namePenaeus kroyeri.[1]It was transferred to the genusXiphopenaeusin 1869 bySidney Irving Smith.X. kroyerihas been considered conspecific with thePacificspeciesX. riveti,but recentgenetic analysisindicates that the two are separate species, and thatX. kroyeri(sensu stricto) may even constitute twocryptic species.[3]
