"This Hypselodoris individual is juvenile so I cannot decide whether it is Hypselodoris nigrostriata (because of the diagonal lines across the mantle) or Hypselodoris zephyra (because of the lack of a distinct yellow margin). That is assuming they are different species โ as I have said several times before I think they are just colour forms of the same species."
