A damaged Aglaja tricolorata

Concerning message #21676:
Hi Bill,
It seems that even Aglaja has repulsive chemicals to avoid aggression. This photo shows that even though a first bite can cause quite a lot of damage, the animal survives.
Locality: Cagnes, 4 m, France, Mediterranean sea, 29 August 2008, muddy. Length: 40 mm. Photographer: Dominique Horst.
Kind regards,

Dear Dom,
Thanks for the photos. Like most sea slugs, aglajids have skin glands which deter predators. Two other things I can note in your photos is that the animal is being 'trailed' by another [see your message #21709] and in the close-up alongside I can just make out the sensory bristles which are characteristic of aglajids and occur in clusters on each side of the mouth. They are most obvious in the genus Chelidonura [see C. hirundinina Fact Sheet].
Best wishes,
Bill Rudman
