Mahimahi the Lungfish was a one-shot manga initially published under "Toriyama's Animal Chronicles" (Weekly Shonen Jump 1999, No. 4/5). For this project, Toriyama simply observed his pet lungfish and illustrated his thoughts about its mysterious nature. Don't let that description fool you, though; the author's trademark warm and comical sense of humor is all over this manga, making it a fantastic way to learn about this unique species of fish! However, it's somewhat hard to track down due to never being released as its own comic, leading many to regard it as an elusive masterpiece.
