Comment from Nathalie Yonow on photo #21615
This is a juvenile Hexabranchus. You can tell by the six gills being inserted into separate pockets. I think sanguineus is endemic to the Red Sea and all the others are marginatus.

A very small juvenile individual.

Individuals with this uniformly dark orange (or red) colour form only occur in the Red Sea and east African coast.

Comment from Richard Willan on photo #17022
This individual displays a most remarkable colour form. I have not seen anything like it ever before.

You can just see part of the 'frilly' oral lappets on the left side

Comment from Nathalie Yonow on photo #2127
Perfect shot of the oral lappets!

A typical individual from the Red Sea and western Indian Ocean which is all red without white markings.

Comment from Richard Willan on photo #2642
In being uniformly red, this individual is more like those from the Red Sea than elsewhere in the tropical Pacific Ocean.

Comment from Richard Willan on photo #812
A rather small individual. Specimens of Hexabranchus sanguineus from the Indo-Pacific (like this one) have white lateral blotches on the mantle, whereas those from the Red Sea (the type locality) have a completely red mantle.
