What Are Barracudas?
Barracudas, from the genus Sphyraena, are a ferocious species of fish that embody sleekness, agility, and raw power.
Thanks to their elongated shape and razor-sharp teeth, they are perfectly adapted for life in the ocean.
They are feared for their formidable speed and ability to strike prey with unbelievable precision.
The fish range in size from the gargantuan great barracuda (Sphyraena barracuda) to the more comparably diminutive Lucas barracuda (Sphyraena lucasana).
Regardless of size, all barracuda share similar physical traits– such as a spinous anterior dorsal fin, rayed posterior dorsal fin, and elongated body– making them efficient hunters.
The origin of their name is thought to come from the Spanish word “barraco,” meaning “shack.”
