Strombus alatus, the Florida fighting conch, is a species of medium-sized, warm-water sea snail, a marine gastropod mollusk in the family Strombidae, the true conchs.

Strombus means, in Latin, a snail with spiral shell, which derives from the Greek στρόμβος, meaning anything turned or spun around, like a top or, as in Aristotle's Historia Animalium, a sea snail.

[1][3] This species is closely similar to Strombus pugilis, the West Indian fighting conch, which has a more southerly range.

S. alatus shells have less prominent subsutural spines and slightly more projected outer lips.

[4] In an extensive study of the Stromboidea in 2005, Simone provisionally treated these as distinct species, but observed, "no spectacular morphological difference was found [and] all related differences, even those of the genital system, can be regarded as extreme of variation of a single, wide distributed, variable species.
