Genetic identification of a rare record of Ommastrephes Bartramii (Cephalopoda: Ommastrephidae) from the Eastern Adriatic Sea

Area of Science:

• Marine Biology
• Zoology
• Genetics

Background:

• The Ommastrephidae family, encompassing commercially important squid species, is globally distributed.
• This family is traditionally classified into three subfamilies: Illicinae, Todarodinae, and Ommastrephinae.
• Ommastrephes bartramii, the neon flying squid, is a notable member of this family.

Purpose of the Study:

• To report and genetically confirm the presence of the neon flying squid (Ommastrephes bartramii) in the Adriatic Sea.
• To establish a genetic baseline for Ommastrephes bartramii in this region.
• To contribute to the understanding of cephalopod distribution and biodiversity.

Main Methods:

• A specimen of neon flying squid was collected in the Adriatic Sea (Croatia) in winter 2013.
• Genetic identification was performed using the standard mitochondrial cytochrome c oxidase subunit I (COI) barcode region.
• DNA sequencing and analysis were conducted to confirm the species identity.

Main Results:

• The collected specimen was genetically identified as Ommastrephes bartramii.
• This represents the first genetic record of the neon flying squid in the Adriatic Sea.
• The finding confirms the presence of this species in a previously unrecorded marine ecosystem.

Conclusions:

• The Adriatic Sea is a newly identified habitat for the neon flying squid (Ommastrephes bartramii).
• Genetic identification is crucial for accurate species distribution mapping.
• This discovery highlights the importance of continued marine biodiversity research in under-explored regions.
