Those silvertip nudibranchs   Wow Seascapeza Its great to see all these new nudibranch articles Well done I just wanted to say that I certainly understand your logic in using the same image to illustrate two different species since they cannot be visually discriminated by looking at the whole animal but I think you should use the caption line in the taxobox to explain that the image is either Janolus capensis or Janolus longidentatus  I also wanted to say one more thing when you call an unnamed species species  or whatever you need to say which author referred to it as that  Anyway well done and keep up the good work  Best wishes
