The complete sequence (14,130 bp) of the mitochondrial DNA (mtDNA) of the land snail Albinaria coerulea was determined. It contains 13 protein, two rRNA and 22 tRNA genes. Twenty-four of these genes are encoded by one and 13 genes by the other strand. The gene arrangement shares almost no similarities with that of two other molluscs for which the complete gene content and arrangement are known,...

This study documents a new deep-sea chiton from the Haima cold seeps. Thermochiton xui . nov. is third species of genus and first occurrence this in South China Sea. identified by its morphological characteristics molecular sequence reported for time. The placement determined phylogenetic tree Ischnochitonidae Maximum Likelihood (ML) Bayesian inference (BI) methods, based on sequences mitochond...

BACKGROUND Many deep-sea benthic animals occur in patchy distributions separated by thousands of kilometres, yet because deep-sea habitats are remote, little is known about their larval dispersal. Our novel method simulates dispersal by combining data from the Argo array of autonomous oceanographic probes, deep-sea ecological surveys, and comparative invertebrate physiology. The predicted parti...
