1st image cropped from 2nd. (I have left the 2nd photo up because it adds perspective wrt the terrain).
Among cup sponges on a dive.Once known as Turbo jourdani.
Reputedly largest turbo shell (or heaviest?) in southern hemisphere but I am way out of touch here😑
SMITH BAY boat dive from Arriba(catamaran). 3 mediocre pics of the only one of this species I saw,and my ID is provisional only.
Old slide scan,so date now given is probably very inaccurate but correct date is recorded in my archived dive logs.
Scuba dive ,but depth range is an estimate only.
