Background
- From the Scorpaenidae family of camouflaged bottom-dwelling fish

- Symptoms peak at 60-90 minutes
- Duration: 1-2 days
Differential Diagnosis

- Toxins
- Ciguatera
- Scombroid
- Tetrodotoxin (e.g. pufferfish)
- Shellfish poisoning

- Portuguese man-of-war
- Sea anemones
- Seabather's eruption
- Phylum porifera (sponges)

Evaluation
- Clinical diagnosis, no specific testing available
Management

- Stonefish envenomations with severe toxicity can be treated with antivenin obtained through poison control
