In this paper, the circular mitochondrial genome of Amphioctopus aegina (Cephalopoda: Octopodidae) was sequenced. The whole mitogenome of A. aegina was 15 545 base pairs (bp) in length with a base composition of 42.53% A, 33.26% T, 16.70% C, and 7.51% G. The complete mitogenome contained 13 protein-coding genes (PCGs), 2 ribosomal RNA genes, 22 transfer RNA genes, and a major non-coding region. The gene arrangements of A. aegina showed remarkable similarity to other Octopodidae species reported. The phylogenetic relationships were reconstructed with the concatenated sequences of the 13 PCGs of the mitochondrial genome, and illustrated that A. aegina had the closest genetic relatives to A. fangsiao.
本文对艾氏耳乌贼（头足纲：蛸科）的环状线粒体基因组进行了测序。艾氏耳乌贼的完整线粒体基因组长度为15545个碱基对（bp），碱基组成为：腺嘌呤（A）42.53%、胸腺嘧啶（T）33.26%、胞嘧啶（C）16.70%、鸟嘌呤（G）7.51%。完整的线粒体基因组包含13个蛋白质编码基因（PCG）、2个核糖体RNA基因、22个转运RNA基因和一个主要的非编码区。艾氏耳乌贼的基因排列与已报道的其他蛸科物种表现出显著的相似性。利用线粒体基因组13个PCG的串联序列重建了系统发育关系，结果表明艾氏耳乌贼与方氏耳乌贼的亲缘关系最近。
