초록

In this study, we performed morphological identification and phylogenetic analysis in domestic distribution samples and direct collected samples in order to exactly identification for possible or currently imported cephalopod from the Southeast Asian countries (Thailand, Indonesia, Vietnam and China). We collected samples at august 2015 in Thailand Hat Yai, Songkhla, Indonesia Medan, Vietnam Ho Chi Minh and Vung Tau. But China, we collected samples at middle of September due to closed season. A total 23 species of cephalopods were identified three order four family nine genus 23 species which is 1 family 3 genus 9 species in Octopoda, 1 family 2 genus 8 species in Sepiolioda, 2 family 4 genus 6 species in Teuthoidea. The 18 species were conducted phylogenetic analysis using cytochrome oxidase I (COI) which is well-known as molecular phylogenetic marker, except the 5 species by sequencing results showed severe variation or sequencing unsuccessful. The results of 18 cephalopods COI phylogenetic analysis were consistent with morphological identification. The excluded 5 species should be need further studies as re-analysis and detailed analysis.
