Birdfish

Fly Fish are strange bird-fish hybrids found in the Turtle Zone of Super Mario Land 2: 6 Golden Coins. Much like Cheep-Cheeps, they jump out of a body of water and attack anything in their way. However, Fly Fish glide in the air a bit longer than Cheep-Cheeps. To defeat a Fly Fish, Mario had to either throw a Fireball or a Green Shell at one.
