Semirossia is a genus of bobtail squid comprising three species.[1]
Description
[edit]Semirossia appears very similar to other members of the Rossiinae subfamily, such as Rossia and Neorossia, from which it can be distinguished primarily by the presence of a functional black pouch connected to the photophores and by the fact that, in the male, only the left dorsal arm has been transformed into a hectocotylus.[2]
Both S. equalis and S. tenera reach a mantle length of 50 mm.[3]
Species
[edit]- Semirossia equalis Voss, 1950, greater bobtail squid
- Semirossia patagonica Smith, 1881
- Semirossia tenera (Verrill, 1880), lesser bobtail squid
