Bigfin reef Squid, Sepioteuthis lessoniana, commonly known as the glitter squid or oval squid, is a 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 cfyptic species complex. The species is likely to include several very similar and closely related species. Bigfin reef squids are characterised by a large oval fin that extends throughout the margins of its mantle, giving them a superficial similarity to cuttlefish. They are small to medium-sized squids, averaging 3.8 to 33 centimetres in length.

The European squid or common squid (Loligo vulgaris) is a large squid belonging to the family Loliginidae. It occurs abundantly in coastal waters from the North Sea to at least the west coast of Africa. This species lives from sea level to depths of 500 m. Its mantle is up to 40 cm long. The species is extensively exploited by commercial fisheries.
