João Pedro Silva The larger one looks like a Janolus sp. but I've never none like this.
Stewart Clarke My thinking was some type of Janolus as well but can't find any similar
João Pedro Silva It has some similarities to J. eximius but that's restricted to New Zeland...
Stewart Clarke We are finding quite a few Nudis that are usually only found in far away places - we think the oil tankers bring them in via ballast water
João Pedro Silva Gary Cobb, have you seen this yet?
Gary Cobb Similar yes but I don't think this is J. eximius. And I have not seen this one! Janolus sp. for sure! Ballast from ships probably but if J. eximius is a direct developer I doubt it. You could call this one Janolus cf. eximius!
Vishal Bhave One species described from Okha, India as Janolus indicus , We have simillar looking species in Gulf of kutch, Gujarat (http://www.nudipixel.net/photo/00026370/location/gujarat/)
Stewart Clarke Vishal, thanks for this. We figured it out eventually with help from Gary and Nathalie Yonow
