The white-bottomed sea cucumber, Actinopyga lecanora, is a valuable inshore fisheries resource which is famous for its high nutrition and pharmacological compounds. However, due to morphological pl...

Sea urchins (Echinoidea) are key components of marine benthic communities and many are commercially important fishery resources as luxury and healthy seafood. However, despite their high ecological and economic value, the mitochondrial genomes of all sea urchins have yet to be analyzed. In this study, we report the first complete mitochondrial genome of Stomopneustidae from Stomopneustes variolaris. The mitogenome has 15,767 base pairs (59.77% A + T content) and contains 37 genes (13 protein-coding, 22 transfer RNAs and 2 ribosomal RNAs), plus a putative control region. This study provides useful molecular resources for clarifying evolutionary and phylogenetic histories of sea urchins.

The true crabs (Brachyura) including Calappidea are one of the most diverse groups of Decapod crustaceans However, despite their great diversity and commercial importance, phylogenetic and classifi...

Miters including Mitra chinensis are important fishery resources in China. However, the phylogenetic and taxonomic studies in Mitridae have been limited. In this study, we report the first complete mitochondrial genome of M. chinensis. The mitogenome has 16,238 base pairs (66.9% A + T content) and is made up of a total of 37 genes (13 protein-coding, 22 transfer RNAs, and two ribosomal RNAs), plus a putative control region. This study will provide useful molecular resources for addressing taxonomic and evolutionary issues in Neogastropoda.

Chicoreus asianus is an ecologically and economically important species of Muricidae, which comprises a highly diverse group of carnivorous marine snails. However, the taxonomic classification and ...

Phascolosoma is one of the most important genera of Sipuncula, many species of which including P. scolops are economic important species in the fishery of southeast China. However, the synonym and ...

The deep-water redfish, Actinopyga echinites, is an ecologically and economically important holothuroid in China due to its valuable nutrition and pharmacological compounds. However, the taxonomy and phylogeny of the Actinopyga have been debated and misidentifications have been reported recently. Moreover, there remain considerable doubts about cryptic species complex within Actinopyga. In this study, we report the first complete mitochondrial genome of Actinopyga from A. echinites. The mitogenome has 15,619 base pairs (62.9% A + T content) and made up of a total of 37 genes (13 protein-coding, 22 transfer RNAs, and 2 ribosomal RNAs), and a putative control region. This study was the first available complete mitogenome of Actinopyga and will provide useful genetic information for future phylogenetic and taxonomic classification of Holothuriidae.

Siphonosoma cumanense is economic important species in the fishery of southeast China. However, the current classification and the phylogeny of genus Siphonosoma had not been verified yet. Here, we report the complete mitochondrial genome sequence of S. Siphonosoma. The mitogenome has 15,917 base pairs and made up of total of 38 genes (13 protein-coding, 23 transfer RNAs and 2 ribosomal RNAs), and a putative control region. This study was the first available complete mitogenomes of Siphonosoma and will provide useful genetic information for future phylogenetic and taxonomic classification of Sipuncula.

Mammilla mammata is an ecologically and economically important species of Caenogastropoda, which is the largest and most evolutionary successful group of marine gastropods. However, the phy...

The rare-spined murex (Murex trapa) is an ecologically and economically important species of Muricidae, which comprises a highly diverse group of predatory marine snails. However, the taxonomic classification and phylogenetic studies have so far been limited. In this study, we report the first complete mitochondrial genome of Murex from M. trapa. The mitogenome has 15,408 bp (66.3% A + T content) and made up of total of 37 genes (13 protein-coding, 22 transfer RNAs, and 2 ribosomal RNAs), and a control region. This study provided the first complete mitogenome of Murex and will provide useful genetic information for future phylogenetic and taxonomic classification of Muricidae.

The black sea cucumber, Holothuria leucospilota, is an ecologically and economically important holothuroid in China due to broader environmental adaptation and valuable pharmacological compounds. However, the wild stocks of H. leucospilota, have been declining steadily due to overexploitation in recent years. The stock enhancement programme has become an increasingly important priority. In this study, we report the complete mitochondrial genome of H. leucospilota. The mitogenome has 15,839 base pairs (57.6% A + T content) and made up of total of 37 genes (13 protein-coding, 22 transfer RNAs and 2 ribosomal RNAs), and a putative control region. The complete mitogenomes of H. leucospilota will provide useful genetic information for future conservation and management of this valuable and vulnerable species.

The sea cucumber, Stichopus monotuberculatus, is an economically important holothuroid in China due to its larger body size and valuable nutrition. However, the taxonomic revision studies of Stichopodidae have been one of the most controversial issues in recent years. Moreover, there remain considerable doubts about a complex of cryptic species within S. monotuberculatus. In this study, we report the complete mitochondrial genome of S. monotuberculatus. The mitogenome has 16,274 base pairs (60.4% A + T content) and made up of total of 37 genes (13 protein-coding, 22 transfer RNAs and 2 ribosomal RNAs), and a putative control region. This study adds one more available complete mitogenomes of Stichopus and will provide useful genetic information for future evolutionary and taxonomic classification of Stichopodidae.

Hemifusus tuba is an ecologically and economically important species of Buccinoidea, which comprises an ecologically diverse group of carnivorous marine gastropods. However, the taxonomic classification and phylogenetic studies have so far been limited. In this study, we report the first complete mitochondrial genome of Melongenidae from H. tuba. The mitogenome has 15,483 bp (68.2% A + T content) and made up of total of 37 genes (13 protein-coding, 22 transfer RNAs, and 2 ribosomal RNAs), and a control region. This study was the first to provide complete mitogenome of Melongenidae and will provide useful genetic information for future phylogenetic and taxonomic classification of Buccinoidea.
