Dear Vishal,

Yes I would agree that this is most probably Okenia pilosa. I haven't seen one with yellow pigmentation on the rhinophores like in your photos, but since we have so few records of the species we still have much to learn. As you will see from the species Fact Sheet it is at present recorded from New Caledonia, China (Hong Kong), Papua New Guinea and north-eastern Australia, so your find from western India is a significant, though not surprising, increase in its known distribution.

Best wishes,
Bill Rudman
