Key identification features
- Moderately built flyingfish, typically 8-12 inches long, with a dark blue back and silvery sides
- Pectoral fins distinctly dark to blackish, lacking the pale bands or clear patches seen in related species
- Pelvic fins comparatively short, not reaching far down the body, marking it as closer to a two-wing type
- Deeply forked tail with a longer lower lobe, standard for flyingfish
- Small upturned mouth and a compact, blunt head
Common look-alikes
- Bandwing Flyingfish: pectoral fin shows an obvious pale crossband rather than being uniformly dark from base to tip
- Tropical Two-wing Flyingfish: pectoral fins are plain dusky or clear rather than distinctly blackish
- Atlantic Flyingfish: pectoral fins are dusky but not as deeply blackened, and the body tends to run slightly larger
Where you'll see one
Occurs in warm offshore surface waters across tropical and subtropical oceans, frequently seen well away from shore gliding low over ocean swells, often at night around the lights of anchored vessels.
Frequently asked questions
What is the clearest way to identify a Blackwing Flyingfish?
Focus on the pectoral fin color; a uniformly dark to near-black wing without pale bands or clear patches is the most distinctive and reliable field mark for this species.
How do I avoid confusing it with the Bandwing Flyingfish?
Look closely at the wing pattern rather than just overall darkness; the Bandwing shows a defined pale crossband interrupting the dark wing, while the Blackwing's fin stays evenly dark throughout.
