The snapping shrimp (family Alpheidae) has a unique natural history as an infaunal symbiont of larger burrowing crustaceans. The mitogenome of was sequenced, the first for a symbiotic representative of the family and the first for a species outside of the genus . The complete mitogenome was 15,463 bp in length and included 13 protein-coding genes, 12 tRNAs, and 2 rRNAs. The gene order matched all known alpheid mitogenomes. Similar to other caridean mitogenomes, the nucleotide composition was A + T biased (62%). A maximum-likelihood phylogenetic analysis of caridean mitogenomes strongly supported monophyly of the family Alpheidae.

Non-invasive bioimaging techniques like X-ray micro-computed tomography (μCT), combined with contrast-enhancing techniques, allow the 3D visualization of the central nervous system , without the destruction of the sample. However, quantitative comparisons of the most common fixation and contrast-enhancing protocols are rare, especially in marine invertebrates. Using the snapping shrimp () as a model, we test three common fixation and staining agents combinations to prepare specimens prior to μCT scanning.

A new species of Chopra, 1923, a parasitic isopod genus of the family Bopyridae found parasitizing two species of the snapping-shrimp genus Spence Bate, 1888, is described from Brazil. This is the first record of in the Atlantic Ocean, and the first species of bopyrid parasite recorded from the Fernando de Noronha archipelago in northeastern Brazil. Females of sp.

A new snapping shrimp, Alpheus midas sp. nov., is described based on two male specimens caught at a depth of 15-20 m off the coast of Ceará, north-eastern Brazil.
View Article and Find Full Text PDFThe snapping shrimp family Alpheidae Rafinesque, 1815 includes numerous species, most of which present controversial geographical distributions. The disjunct distribution of Alpheus simus Guérin-Méneville, 1856 in the western Atlantic, from Florida to the south of the Caribbean Sea and then from Rio Grande do Norte to Bahia in Brazil, suggests that Brazilian material may belong to an undescribed species. The examination of specimens previously identified as A.
