The following is an AI-summarised digest:

Philinopsis gigliolii (kanoko-kisewata) and P. speciosa (karasu-kisewata) can be told apart by several morphological and molecular characters.

Morphological differences

  • Body colour: P. gigliolii is dark brown to black with yellow or white spots; P. speciosa is generally bluish-green or purple.
  • Body shape: P. gigliolii is elongate and smooth in outline; P. speciosa is somewhat broader.
  • "Tentacles": Both species have tentacles, but their shape and arrangement differ subtly.
