Photographic
evidence for the regression of fibropapillomas afflicting green
turtles at Honokowai, Maui, in the Hawaiian Islands
Peter Bennet & Ursula Keuper-Bennet
Over 10 summers (1988-1998), we have
used underwater photography and video to document the expression of fibropapillomatosis
in individual turtles at Honokowai, Maui, in the Hawaiian Islands. Approximately
200 turtles of all sizes have been identified, 37% of which have been sighted
in more than one summer. Of these, over 70% have or have had FP.
By examining the visual record and
applying a tumour scoring system developed in Hawaii, we were able to show
moderate to complete regression in a significant percentage (over 30%)
of the afflicted turtles that we have sighted in more than one summer.
This presentation demonstrates the methods used to identify the turtles
and to process the images that constituted our evidence. We describe how
the resulting data were captured and analyzed using a database, and present
the results. Finally, we provide graphic examples of regression in several
turtles that we have known over the years. |
