Are these all Ceratosoma amoena?

August 10, 2000
From: Des Paroz

Hi Bill

Looking at some photos in my recently scanned batch of slides, and I have three different nudis that I would have thought at first were all Ceratosoma amoena.

However, if they are, there are distinct differences in the colourations, and even their shapes.

(Appologies for the third image, my scanning has washed it out a bit)

Would be interested in your comments on this, pretty common, species.

Best regards

Dear Des,
Some information on where and when these were photographed would be useful. If you have a look at the other photos at the top of the Ceratosoma amoena Page, and in the other messages on this page, you will find quite a variety of colour forms. Although they don't fit a perfect geographic sequence, specimens from New Zealand are usually much pinker without much in the way of red, and specimens from Western Australia have many small yellow spots. That's why geographic information on colour forms is useful as it helps us build up a picture of the variation found in the species whcih is found from New Zealand to southwestern Australia.

Best wishes,
Bill Rudman.
