A remarkable shot of the head showing the large branched oral tentacles (that are unique to Hexabranchus) just underneath the front of the mantle.

This photo shows a juvenile Hexabranchus sanguineus that has just grown to the size where it is able to fold the edges of its mantle over its back (I would guess about 40 mm long)– notice the separate gills with the anus in the middle of them appearing as a small white papilla.

Comment from Richard Willan on photo #3223
Note the separate gills that cannot be contracted beneath the mantle surface.

Comment from Richard Willan on photo #1063
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.

Detail of gills with commensal shrimp Periclimenes imperator.

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.
