Bigfin Reef Squid

Sepioteuthis lessoniana


Sepioteuthis lessoniana, commonly known as the bigfin reef squid or oval squid, is a commercially important species of loliginid squid. It is one of the three currently recognized species belonging to the genus Sepioteuthis. Studies in 1993, however, have indicated that bigfin reef squids may comprise a cryptic species complex. The species is likely to include several very similar and closely related species. They are not very big in size, usually up to 12 inches.


Coastal reefs, mostly water column especially near the surface.

Wonderful capture Albert, and congratulations it's earned you another well-deserved Spotting of the Day! The bigfin reef squid may not look like it's built for speed, but it can swim as fast as 15 meters per second to escape predators!

Thanks, @Adarsha, @Mark, @sunnyjosef and @Bhagya for your kind comments :)
It was not possible to get both Squids in sharp focus, they were not too big, around 6-7 cm in length. The Feather Star arms on the left give the perspective of the size.
I was trying to capture the image as though the second Squid at the back is the mirror reflection :D
