Damaged Chromodoris tinctoria

September 20, 2005
From: Chris Cunnold

Dear Bill,
I continue to see Chromodoris tinctoria at this sight with this appearance. This is the third time I have observed multiple numbers in this deformed / injured state. Another sight about a kilometre away has plenty of healthy specimens. Do you have any idea of the cause?

Dear Chris,
This is definitely damage rather than some genetic or developmental deformity. From the diamond-shaped nature of the wounds, it's possible some fish with a beak-like mouth - perhaps a parrot fish? - might have done this. Another possibility is a cephalopod - perhaps a territorial octopus or cuttlefish?
Best wishes,
Bill Rudman
