Key identification features
- Long, laterally compressed, torpedo-shaped body, silvery with a blue-green back
- Large mouth reaching well past the eye, lined with prominent fang-like teeth
- Deeply forked tail fin and a short dorsal fin set far back on the body
- No scales on the head; body scales are small and easily shed
- Can grow to well over 1 m (3 ft), unusually large for a herring relative
Common look-alikes
- Milkfish: similar silvery torpedo shape but has a small, toothless mouth, unlike the wolf herring's fang-filled jaw
- Barracuda: also has large teeth and an elongated body, but a barracuda has two well-separated dorsal fins and a rounder cross-section, while the wolf herring has a single dorsal fin and a flattened, blade-like body
- Sardines and true herrings: much smaller, blunt-mouthed, and lack large visible teeth
Where you'll see one
Wolf herring cruise in loose schools through coastal and estuarine waters of the Indo-West Pacific, from the Red Sea and East Africa to Southeast Asia and northern Australia, often near river mouths and over sandy or muddy bottoms.
Frequently asked questions
How do I tell a wolf herring from a barracuda?
Look at the dorsal fins and body shape: a wolf herring has a single short dorsal fin and a flattened, blade-like body, while a barracuda has two separated dorsal fins and a more cylindrical body.
What's the easiest feature to spot on a wolf herring?
Its unusually large, fang-like teeth in a mouth that extends well past the eye, a trait no true sardine or herring shares.
