Stenopodidea Claus, 1872 (Crustacea: Decapoda) is one of the major groups of decapods crustaceans. Hitherto, only one complete mitochondrial genome (mitogenome) from the family Stenopodidae is available for the infraorder Stenopodidea. Here, we determined the complete mitogenome of Spongiocaris panglao de Grave and Saito, 2016 using Illumina sequencing, representing the first species from the family Spongicolidae. The 15,909 bp genome is a circular molecule and consists of 13 protein-coding genes (PCGs), 2 ribosomal RNA (rRNA) genes, 22 transfer RNA (tRNA) genes and one control region...

There are a limited number of model species for decapod experimental embryology. To improve our understanding of developmental pattern evolution in the Decapoda, here we describe the early embryonic development of the caridean shrimp Lysmata boggessi, from immediately after fertilization to the hatching of the zoea larva, using fluorescence microscopy and whole-mount nuclear staining with 4',6-diamidino-2-phenylindole. Lysmata boggessi follows the standard caridean pattern of early development, with early holoblastic cleavage that will later become superficial, to form a blastoderm...

Macrobrachium amazonicum is a commercially important freshwater prawn with a high degree of reproductive plasticity. The species is classified into two groups: coastal populations, with larger individuals exhibiting high fecundity and needing brackish water for larval development; and continental populations, with smaller specimens exhibiting low fecundities and completing metamorphosis in freshwater. The objective of this study was to investigate the influence of environmental factors in the fecundity, egg size and volume, and reproductive output in females of M...

We report a new microsporidium from a key species of the estuarine communities of the Gulf States, the Riverine grass shrimp, Palaemonetes paludosus. A milky-white shrimp was found in the Mobile Bay Delta, a large, oligohaline-freshwater wetland in Alabama, USA. Light microscopy of smears and thick sections of the abdominal tissues demonstrated infection with microsporidian spores enclosed in sporophorous vesicles (SVs) in sets of eight. Broadly oval spores measured 2.9 ± 0.06 × 1.7 ± 0.03 µm (2...

A new species of alpheid shrimp, Thuylamea shiranui, is described and illustrated on the basis of five specimens from Yatsushiro Sea, western Kyushu, Japan. It is closely related to T. camelus Nguyên, 2001, the type species of the heretofore monotypic genus Thuylamea Nguyên, 2001, known from South China, Vietnam and Singapore. The complete lack of submedian posterodorsal crests on the carapace and the relatively long antennular peduncle distinguish the new species from T. camelus. The generic diagnosis of Thuylamea is emended to accommodate the new species...

One new species and three new distribution records for the family Crangonidae (Crustacea: Decapoda) are reported from Western Australia. A new species, Philocheras gardenensis sp. nov. is described and illustrated based on specimens collected from the Western Australia. The new species closely resembles Philocheras fasciatus (Risso, 1816), but can be distinguished easily by the absence of lobe-like folds on either side of the middle line of the carapace, the presence of a lateral carina extending from the branchiostegal spine, the longer middorsal carina and distolateral tooth of the antennal scale...

The family Crangonidae comprises 22 genera and 219 species. Six species are recorded in the Southwestern Atlantic. In this paper, two species of this family, Pontophilus brevirostris Smith, 1881 and Sabinea hystrix (A. Milne-Edwards, 1881) are recorded for the first time to southwestern Atlantic Ocean. Additionally, we record the occurrence of Parapontocaris caribbaea (Boone, 1927), Parapontophilus gracilis (Smith, 1882) and Philocheras gorei (Dardeau, 1980) to the Northeast of Brazil. Through this paper, we raised the number of Cragonidae species to eight from recorded from southwestern Atlantic (Brazilian deep waters)...

Two species of alpheid shrimp collected from a marine cave off Ie Island, Okinawa Islands, Ryukyu Islands, Japan, are reported. Caligoneus cavernicola n. gen., n. sp., is described on the basis of six specimens, including two ovigerous individuals. The new monotypic genus shares a number of features with Salmoneus Holthuis, 1955 and Triacanthoneus Anker, 2010; however, the dorsally elevated rostrum and the symmetrical pereopods 1 (= chelipeds) of "minor form" distinguish Caligoneus n. gen. from the latter two genera...

Caridea, an infraorder of shrimps coming under Pleocyemata was first reported from the oceans before 417 million years followed by their radiation recorded during the Permian period. Hitherto, about 3877 extant caridean species were accounted within which one quarter constitute freshwater species. Freshwater prawns of genus Macrobrachium (Infraorder Caridea; Family Palaemonidae), with more than 240 species are inhabitants of diverse aquatic habitats like coastal lagoons, lakes, tropical streams, ponds and rivers...

Fresh caught Clibanarius vittatus [SW, 31‰ salinity (S)] were acclimated to a dilute medium (15‰ S) for 10 days, employing silver staining to locate gill ion transporting tissue, immunofluorescence to localize the Na+ /K+ -ATPase α-subunit in the lamellae, and electron microscopy to portray ultrastructural changes in the gill epithelia. Na+ /K+ -ATPase activity was characterized kinetically in a gill microsomal fraction, including synergistic stimulation by NH4 + plus K+ . Silver staining revealed that all 26 phyllobranchiate arthro- and pleurobranchiae participate in ion transport...

Some Macrobrachium shrimps (Caridea, Palaemonidae) are diadromous; freshwater adults are truly euryhaline, while larvae need saline water for development. Branchial Na+ /K+ -ATPase (NKA) and carbonic anhydrase (CA) are involved in NaCl absorption in freshwater. This study aimed at verifying the time course of the osmoregulatory response of adult Macrobrachium acanthurus to high salinity brackish water (20‰), from the first 30min to 5days. The goal was to detect possible transition from hyper- to hyporegulation, the putative involvement of branchial NKA and CA, or the induction of muscular HSP70 expression...

Deep-sea hydrothermal vent is one of the most extreme environments on Earth with low oxygen and high levels of toxins. Decapod species from the family Alvinocarididae have colonized and successfully adapted to this extremely harsh environment. Mitochondria plays a vital role in oxygen usage and energy metabolism, thus it may be under selection in the adaptive evolution of the hydrothermal vent shrimps. In this study, the mitochondrial genome (mitogenome) of alvinocaridid shrimp Shinkaicaris leurokolos (Kikuchi & Hashimoto, 2000) was determined through Illumina sequencing...

The commercial deep-sea caridean shrimp Heterocarpus gibbosus Spence Bate, 1888 has long been recorded from India and constitutes an important part of the catches in the context of the further development of deep-sea fisheries in India. A recent survey in some deep-sea fishing ports in southern India, however, revealed that all material previously reported as " H. gibbosus " is actually a misidentification of its closely related species H. chani Li, 2006, which has only recently been reported from India...

Ecologists have been largely interested in the description and understanding of the power scaling relationships between body size and abundance of organisms. Many studies have focused on estimating the exponents of these functions across taxonomic groups and spatial scales, to draw inferences about the processes underlying this pattern. The exponents of these functions usually approximate -3/4 at geographical scales, but they deviate from this value when smaller spatial extensions are considered. This has led to propose that body size-abundance relationships at small spatial scales may reflect the impact of environmental changes...

Caridean shrimps constitute one of the most diverse groups of decapod crustaceans, notwithstanding their poorly resolved infraordinal relationships. One of the systematically controversial families in Caridea is the predominantly pelagic Pasiphaeidae, comprises 101 species in seven genera. Pasiphaeidae species exhibit high morphological disparity, as well as ecological niche width, inhabiting shallow to very deep waters (>4000m). The present work presents the first molecular phylogeny of the family, based on a combined dataset of six mitochondrial and nuclear gene markers (12S rDNA, 16S rDNA, histone 3, sodium-potassium ATPase α-subunit, enolase and ATP synthase β-subunit) from 33 species belonged to six genera of Pasiphaeidae with 19 species from 12 other caridean families as outgroup taxa...
