Similar Species
The only other dolphinfish is the pompano dolphinfish. They do not grow to the sizes that the common dolphinfishes do. The easiest way to differentiate them is by the anal fin. The common dolphinfish's anal fin is concave at the anterior end (1st few rays slightly longer). The pompano dolphinfish has a convex, rounded anterior end. Also, the pompano dolphinfish has a squarish tongue patch, while the common dolphinfish has a round tongue patch.
