A week or so ago I was reading an article on blue marlin and the growth rates/age at "Grander"size.
Was pretty surprised.
One of the largest sampled, a female of over 1500 pounds, was just 26 years of age. At birth, they are just millimeters in length. Would fit on the tip of your fingers.
I started down the wikihole reading about them when I was looking at dog fish and their age and life cycle. Dog fish, which is particularly sorry form of shark, are much slower growing, mature later, and rarely exceed 4ft. Yet they are ubiquitous "trash fish" here in the PNW.
The volume of prey a blue marlin must consume to grow past 1k pounds in a relatively short period is astounding.
