The complete mitochondrial genome of Théel, 1886 (Apodida: Synaptidae).

In this study, we sequenced and annotated the complete mitochondrial genome of . The 16,970 bp mitogenome contains 13 protein-coding genes, 22 transfer RNA genes (duplications of and ), and two ribosomal RNA genes. The phylogenetic analysis of the 13 protein-coding genes in echinoderms indicated that has a close evolutionary relationship with (Apodida: Synaptidae).

Characterization of the complete mitochondrial genomes of two sea cucumbers, Deima validum and Oneirophanta mutabilis (Holothuroidea, Synallactida, Deimatidae): Insight into deep-sea adaptive evolution of Deimatidae.

The deep-sea is the largest and most extensive ecosystem on our planet with limited food availability, extreme pressure reaching hundreds of bars, perpetual darkness, frigid temperatures, and minimal oxygen levels. Mitochondria plays a key role in energy metabolism and oxygen usage, thus it may undergo adaptive evolution in response to pressures from extreme harsh environments. In this study, we present the mitochondrial genome sequences of the sea cucumbers Deima validum and Oneirophanta mutabilis collected from the South China Sea.

The complete mitochondrial genome of (Ostreida: Ostreidae): characterization and phylogenetic position.

The taxonomy of the genus is very confused, however, there is relatively little molecular information available on . In this study, we determined and described for the first time the complete mitochondrial genome of . The complete mitogenome of 16,204 bp in length, containing 12 protein-coding genes (lack of gene), two rRNA genes, 23 tRNA genes.

The first complete mitochondrial genome of the Mariana Trench (Asteroidea: Brisingida: Brisingidae) allows insights into the deep-sea adaptive evolution of Brisingida.

Starfish (phylum Echinodermata) are ecologically important and diverse members of marine ecosystems in all of the world's oceans, from the shallow water to the hadal zone. The deep sea is recognized as an extremely harsh environment on earth. In this study, we present the mitochondrial genome sequence of Mariana Trench starfish , and this study is the first to explore in detail the mitochondrial genome of a deep-sea member of the order Brisingida.

Complete mitochondrial genome of Benthodytes marianensis (Holothuroidea: Elasipodida: Psychropotidae): Insight into deep sea adaptation in the sea cucumber.

Complete mitochondrial genomes play important roles in studying genome evolution, phylogenetic relationships, and species identification. Sea cucumbers (Holothuroidea) are ecologically important and diverse members, living from the shallow waters to the hadal trench. In this study, we present the mitochondrial genome sequence of the sea cucumber Benthodytes marianensis collected from the Mariana Trench.
