Honestly! Lets not name anything after a bad James Bond film with blue ring octos that attach to peoples faces!
I think we need to first decide what seperates a fem octo from a male octo, besides sexual organs, and go from there...hen is the fem. of hanna,or hahn (male), etc... most animal distinctions due to sex are based on germanic language (they are particular, aren't they?)...whereas most other languages have single terms for both sexes of animals. HMMM.
Rosemary means "dew of the sea" (fem) but may be too long...but I like the flower connotation (octos are like pretty flowers,yes?) We could go spanish and say "rosita"!
More pondering required.
