Abstract The aim of this study was to describe and illustrate the early larval stages, i.e., complete naupliar development first protozoea (PZI) Sicyonia dorsalis S. typica obtained under laboratory conditions. We also provide remarks from a comparative analysis morphology these stages among representatives genus furnish morphological characteristics distinguish them another penaeoidean in plan...

Abstract The Atlantic seabob shrimp, Xiphopenaeus kroyeri (Heller, 1862) (Penaeidae), is commonly found on western coasts and of high commercial importance in Brazil, Suriname, Guyana. Current genetic resources X. are scarce no genomic studies available. This study reports the complete mitochondrial genome kroyeri. Using pipeline NOVOPlasty, we assembled circularized with an average coverage 68...

The evolutionary history of decapods and their parasites is assessed with particular reference to the use of parasites as proxies for host phylogeny. We focused on two groups of obligate parasites that use decapods as their definitive hosts: parasitic isopods of the family Bopyridae and,parasitic barnacles of the superorder RhizO$<ephala. Bopyrids and rhizocephalans differ in that the rhizoceph...
