Both colour morphs have orange rhinophore clubs, the white morph has orange gills, the bluish morph has bluish gills with orange pigment.
Etymology: Hypselodoris iba is named for the Tagalog word iba, meaning different or distinctive.
This picture shows the two colour morphs mating.
The white morph was identified by Terrence M. Gosliner. Thanks!
Terry wrote in November 2003 he is working on it with his student Rebecca Johnson. 15 years later was the description published...
The white morph is as Hypselodoris sp. 10 in IPN at page 269, it was posted on 15 December 2003 at these websites
as Hypselodoris sp. A Genus: Stimpson, 1855, and changed on 15 August 2011 into Hypselodoris sp. 01 Genus: Stimpson, 1855.
For some genera, such as Trinchesia was the alphabet almost through. I had to change the distinguishing alphabetic character into a number.
I had chosen 2-digit numbers, even though '01' looks a little bit stupid, and now is only the genus italic written.
I changed it on 23 September 2018 into Hypselodoris iba Gosliner & R.F. Johnson, 2018.
