线粒体基因组（线粒体基因组）分析是研究后生动物进化史的重要工具。熊猫科是一个多样化的加勒比类群，主要包含深海物种。截至 2019 年 5 月 30 日，GenBank 中仅提供两个完整的线粒体基因组。在这里，我们通过 Illumina 测序展示了两种深海熊猫虾 Heterocarpus ensifer 和 Bitias brevis 的完整线粒体基因组序列。线粒体基因组长度确定为 15 939 bp 和 15 891 bp，均由 13 个蛋白质编码基因（PCG）、23 个转移 RNA 基因（tRNA）、2 个核糖体 RNA 基因（rRNA）和 1 个控制区组成。核苷酸组成偏向于腺嘌呤和胸腺嘧啶。总体而言，基因内容和排列与胰甲壳动物的基本模式一致。四种熊猫的控制区域的比对揭示了保守序列块（CSB）（长度为104 bp，平均GC％= 29.47％和69.23％相似性）。
The mitochondrial genome (mitogenome) analysis is a significant tool for investigating the evolutionary history of metazoan animals. The family Pandalidae is a diverse caridean group containing mainly deep-sea species. Until May 30 2019, only two complete mitogenomes are available in GenBank. Here we present the complete mitogenome sequences of two deep-sea pandalid shrimps, Heterocarpus ensifer and Bitias brevis through Illumina sequencing. The mitochondrial genomes were determined to be 15 939 bp and 15 891 bp long, and both consist of 13 protein-coding genes (PCGs), 23 transfer-RNA genes (tRNAs), two ribosomal-RNA genes (rRNAs), and one control region. The nucleotide composition is biased toward adenine and thymine. Overall, the gene contents and arrangements are consistent with the pancrustacean ground pattern. The alignment of the control regions of four pandalids reveals a conserved sequence block (CSB) (104 bp in length, average GC%=29.47% and 69.23% similarity).
