A couple of days ago, I was snorkeling when I saw this enormous fish. I snapped a quick photo, fearful that the fish would quickly disappear. But it stuck around for a minute or two, passing back and forth in front of me, before sliding away into deeper water.
I knew it was a jack, but not one I’d seen before. When I got home, I dove into my fish book and figured out this was a giant trevally. According to my fish book, the giant trevally is the largest of the jack family. The biggest recorded catch is one that weighed 191 pounds. That would be heavier than me! That’s a tad worrisome because my fish book also notes that these curious and fearless fish ‘have been known to grab and rip away divers’ bright snorkel tips and colorful fins.’
This one was smaller than that, probably somewhere between three and four feet long, but comfortably the largest jack I’ve ever seen and probably the largest fish I’ve seen of any kind other than rays and sharks.
