Various views of tuna in eco-tourism pen ,some include dive buddy for size comparison.
[Same date and dive(s) as previous observation,however statistically the odds are that these images do not include that lone fish,because there were about 30 or so Southern Bluefin Tuna zooming about in the very spacious and deep-bottomed pen]

(Please also read my description for the previous submission as it applies equally to this one.)
