Field guide
Species is rarely confirmed after a bite — the water is too dark and the encounter too brief. But the surf-line population here is well documented, and it is dominated by two small, fast, bait-chasing species.
Carcharhinus limbatus
Fast, nervous, and abundant. Blacktips run the bait line in dense schools and strike by sight in low visibility. A blacktip bite is typically one shallow, ragged laceration — the shark releases the instant it identifies its mistake.
Carcharhinus brevipinna
Named for the corkscrew leap it makes through bait balls. Nearly indistinguishable from a blacktip in the water, and functionally identical in behaviour and bite pattern. Most reports listing 'blacktip' could equally be spinner.
Carcharhinus leucas
Tolerates fresh water and moves through the inlet and lagoon. Capable of far more serious injury, but very seldom linked to New Smyrna's surf-zone bites, which happen in a few feet of water among crowds.
Carcharhinus plumbeus / Negaprion brevirostris
Both are frequently seen from the pier and from the air. Neither hunts in a way that produces mistaken-identity bites in the whitewater.
Carcharodon carcharias
Tagged whites transit Florida's Atlantic coast in winter, generally well offshore and in deeper water. They are not part of the New Smyrna bite record.
