In any marina where fish are landed, usually filleted etc, are these large game fish waiting for the unwanted bits. They move extremely quickly and I wouldn’t want to fall in.
Our tender will give an idea of their size, they can grow to 8ft long and 280 lbs.
While we were there an iguana swam through, a couple of the Tarpon had a look at it but it managed, in some manner, to scare them off. They could have swallowed it whole.
They are caught at sea as a game fish that is very challenging as they leap a lot but are not good eating and are usually released.
