Have you ever been out on the water and had someone completely confused when you said you wanted to catch a dolphin? Well, you’re not alone!

This conundrum has inspired me to write about the controversial subject: Is a Mahi Mahi a Dolphin?

The short answer is no, mahi mahi and dolphins are completely different animals. This article will clarify the confusion between the two and explain why mahi mahi are sometimes called “dolphinfish”.

Why is Mahi Mahi Called Dolphinfish

Why is Mahi Mahi Called “Dolphinfish”?

The term “dolphin” was first used to refer to mahi mahi because of some shared traits:

  • Agile swimming style
  • Curved body shape
  • Ability to make high-pitched sounds

However, this name causes confusion today since we now know dolphins are an entirely different species. “Mahi mahi” comes from the Hawaiian words for “strong strong” and is now the preferred name.

Other common names for mahi mahi include dorado (Spanish for “golden”) and lampuga (Italian). But there are no mahi mahi species that are actually related to dolphins.

Conclusion

While sometimes confusingly called “dolphinfish”, mahi mahi are definitely not the same as dolphins. They are tasty sustainable fish with no relation to marine mammals.
