Summary

Lionfish stings in home aquariums cause painful injuries, primarily to hands. Some cases may be "empty stings" due to venom delivery system issues.

Area of Science:

  • Marine Biology
  • Toxicology
  • Aquatic Veterinary Medicine

Background:

  • Lionfish (Pterois volitans) are popular in home aquariums.
  • Their venomous spines pose a risk of injury to owners.
  • Previous reports on lionfish envenomation are limited.

Purpose of the Study:

  • To document injuries from lionfish kept in home aquariums.
  • To analyze the clinical presentation and severity of lionfish envenomations.
  • To investigate potential causes of "empty stings" in lionfish.

Main Methods:

  • Retrospective review of injury cases reported to toxicology centers over 3 years.
  • Clinical assessment of patients with lionfish stings.
  • Analysis of venom delivery mechanisms in lionfish.

Main Results:

  • 14 injuries from captive lionfish were recorded, all involving hand punctures.
  • 11 patients experienced intense pain and systemic symptoms.
  • 3 cases presented as "empty stings" without typical envenomation symptoms, possibly due to venom organ structure.

Conclusions:

  • Lionfish stings in home aquariums can cause significant pain and systemic effects.
  • The venom delivery system of lionfish may occasionally prevent toxin injection, resulting in empty stings.
  • Proper handling and awareness are crucial for aquarists keeping lionfish.
