The Blue Marlin is found in the ocean.
The Blue Marlin can be donated to the museum. Upon doing so, the following text is given by Blathers:
"Blue marlins are famous for their long, swordlike noses that give them the nickname "swordfish." They use their "swords" to knock out their prey before capture, not skewering it as you'd think. Able to swim as speeds above 60 mph, their speed and power make them a true test for any angler."
Upon catching the fish, the player will say the following:
"I caught a blue marlin! What a true darlin'!"
