Key marine animal injury statistics
- Divers and swimmers suffer an estimated 40,000 to 50,000 marine envenomations a year[7].
- One California beach, Seal Beach, records 500 or more stingray stings a year; 75% of stings in a 393-person study hit the foot[1].
- Stingray deaths are rare, but they happen: the MSD Manual notes reported deaths, and a barb to the chest killed a 62-year-old aquarium diver[2][4].
- In a 943-fishermen survey, every participant reported a past marine animal injury, and 44.11% reported 4 to 6 episodes[15].
- Ciguatera fish poisoning is estimated at 10,000 to 500,000 cases a year worldwide, depending on the estimate[16].
- About 1 in 5 people with a Vibrio vulnificus infection die[19].

Stingray injury statistics
| Statistic | Figure |
|---|---|
| Reported stings a year, Seal Beach, California | 500 or more[1] |
| Stings to the foot (393 people followed) | 75%[1] |
| Pain fully gone within 1 week | 52%; 94% resolved or improved by 1 month[1] |
| Saw a doctor / took antibiotics | 22% / 17%; none needed hospital admission[1] |
| Pain peak | Within 90 minutes; usually fades over 6 to 48 hours[2] |
| Relief from hot water alone | 65 of 74 people in a 119-case series[3] |

Jellyfish sting statistics
| Statistic | Figure |
|---|---|
| Studies in the 2025 ILCOR first aid review | 7 randomized or quasi-randomized trials and 3 other studies, all very low certainty[5] |
| Hot water vs ice, bluebottle stings | 96-patient trial; 42% matched difference in favour of 45 °C water[5] |
| Vinegar | Studied in 7 studies; worse pain than no treatment in 2[5] |
| Where deaths occur | Mostly the Indo-Pacific, from box jellyfish; one antivenom exists[6] |
| Sea lice (jellyfish larvae) rash | 38 cases in one Brazilian state study[23] |
Guides: jellyfish sting treatment and sea lice rash.
Venomous spine injuries: catfish, lionfish and sea urchins
| Animal | Study | Key statistic |
|---|---|---|
| Catfish | 155 patients, US Gulf South[8] | 38% had complications; arriving 24 to 72 hours late raised the risk 2.70 times |
| Marine catfish | 127 injuries over 8 years, Brazil[9] | About 20% of more than 700 marine animal injuries in the author’s records |
| Lionfish | 117 patients, Martinique[10] | 22% admitted to hospital; 18% local infection; 8% surgery |
| Lionfish | 555 sting victims[11] | Pain peaks at about 1 hour; more than 70% were spearfishing |
| Sea urchin | Bathers, Brazil, 24 months[12] | 64 of 133 marine animal injuries; 93.55% on the sole of the foot |
| Sea urchin granulomas | Review of 36 studies[13] | More than 120 cases; spines can stay visible on X-ray 8 years later[14] |
Marine injury statistics for fishermen
| Study | Crew | Key statistic |
|---|---|---|
| Yu et al., 2026[15] | 943 fishermen, China | All reported a past injury; stingrays, jellyfish and echinoderms most common |
| Marshall et al., 2004[20] | 215 North Carolina fishers | 80% of injuries came from marine animals; 32% of penetrating wounds became infected |
| Kucera et al., 2010[21] | 219 US fishermen | 35% of injuries were penetrating hand wounds; gloves were protective |
For the infections that follow, see fish handler’s disease: in reported erysipeloid endocarditis cases, overall mortality was 38%[22].
Seafood poisoning and infection statistics
| Condition | Key statistic |
|---|---|
| Ciguatera | Estimated 10,000 to 50,000, up to 50,000 to 500,000 cases a year[16]; 19 of 20 sailors ill on one bulk carrier in 2021[17] |
| Scombroid | 192 US outbreaks and 597 illnesses, 2011 to 2023; 76% of outbreaks with a known food were tuna[18] |
| Vibrio vulnificus | About 1 in 5 infected people die, some within a day or two[19] |
How these statistics were chosen
Each figure comes from a peer-reviewed study, a US government source or a professional medical reference, and each links to the original. Numbers are not combined across studies because the studies count different things: emergency visits, survey answers or outbreak reports. Treat study-level figures as what that study found, not as national rates.
For fleets, these numbers point to one plan: puncture wounds, stings and seafood poisoning are predictable, so the first aid steps and the chest stock should match them. Discovery Health MD writes that plan through maritime medical consulting and stocks it through ship medical chest management. Contact our physician team.
Common questions
How many stingray injuries happen each year?
No national count exists, but Seal Beach, California alone records 500 or more reported stings a year[1].
How many people die from stingrays each year?
Deaths are rare; the MSD Manual notes that deaths have been reported, including from chest wounds[2][4].
How many people get stung by marine animals each year?
An estimated 40,000 to 50,000 divers and swimmers are envenomated each year[7].
Which jellyfish cause the most deaths?
Box jellyfish, mostly in the Indo-Pacific[6].
How common is ciguatera poisoning?
Estimates range from 10,000 to 500,000 cases a year worldwide, with heavy under-reporting[16].
How dangerous is Vibrio vulnificus?
About 1 in 5 people with the infection die[19].
How often are fishermen injured by marine animals?
In one survey of 943 fishermen, every participant reported at least one past injury[15].
