Pirambeba-vermelha
The pirambeba-vermelha is a fin-eating piranha native to the Amazon basin.
Unlike the red-bellied piranhas most tourists picture, this species targets the fins and tails of other fish rather than flesh — a feeding habit that makes it a nuisance in gill nets and a curiosity for anglers.
It's caught incidentally across Amazonian waters and occasionally targeted by local fishers.
Scientific Name: Serrasalmus humeralis
Also known as Pirambeba-vermelha, Piranha-de-orelha-preta, Pirambeba
- Compressed, roughly rhomboid body with a serrated keel running along the belly — the feature that gives the genus its name (Latin for "serrated salmon").
- Named for a distinctive black shoulder patch (humeralis = shoulder), which separates it from similar pirambeba species at a glance.
- Reddish coloration on the flanks and belly; sharp, interlocking teeth visible even when the mouth is closed.
- A small species by piranha standards — sources do not give a confirmed maximum size for this species specifically, so treat any large pirambeba as a bonus.
What to know
Habitat Distribution
- Native to the Amazon River basin in Brazil; also recorded in estuarine environments near river mouths.
- Found in both main-channel rivers and smaller tributaries; tolerates a range of water types common to Amazonian drainages.
- Dies at water temperatures below about 11°C, so it is strictly a tropical species confined to Brazil's warmer northern and central river systems.
- Not native to the Pantanal or southern Brazilian drainages; any records there would be incidental or introduced.
Key Locations
- Amazon River basin — the species' core range in Brazil, including main-channel and tributary waters across the Amazon drainage.
- Estuarine zones near Amazonian river mouths, where the species has been recorded in brackish conditions.
Specific Spots
- Near schools of larger fish — pirambebas follow concentrations of other species to pick off fins, so wherever baitfish or mid-sized fish stack up, pirambebas are likely nearby.
- Slack water pockets and eddies off main current, where injured or slow-moving fish are easier targets.
- Around gill nets and fish traps, where trapped fish are vulnerable — this is how most are encountered by local fishers.
Pirambeba-vermelha FAQ
Answers from onWater's species guide.
What are the best lures and bait for Pirambeba-vermelha?
Small chunks of fresh fish flesh or animal fat on a short-shank hook, the traditional and most effective bait used by local Amazonian fishers for piranha species including pirambeba. Small spoons or spinners can draw reaction strikes, but natural bait consistently outperforms artificials for this fin-feeding species.
How do you catch Pirambeba-vermelha?
Most pirambeba-vermelha are caught incidentally by local fishers using hand lines or light spinning gear baited with fish chunks near concentrations of other fish.
What do Pirambeba-vermelha eat?
Primarily eats the fins and tails of other fish rather than whole prey, a behavior called lepidophagy/fin-feeding. This means small, soft-plastic or natural-bait presentations that mimic a struggling fish fragment can draw strikes.
Where do Pirambeba-vermelha live?
Native to the Amazon River basin in Brazil; also recorded in estuarine environments near river mouths. Found in both main-channel rivers and smaller tributaries; tolerates a range of water types common to Amazonian drainages.
