A ratfish spine sting caused severe pain, swelling, and numbness in a fisherman

Area of Science:

  • Marine toxicology
  • Ichthyology
  • Dermatology

Background:

  • Accidental envenomation by marine fauna can lead to significant local and systemic effects.
  • Ratfish (Chimaera monstrosa) possess venomous spines capable of causing injury.

Observation:

  • A fisherman sustained a puncture wound to the right calf from a ratfish spine.
  • Initial symptoms included immediate burning pain, localized swelling, and bluish skin discoloration.
  • Neurological symptoms such as calf numbness and posterior thigh numbness developed subsequently.

Findings:

  • The envenomation resulted in prolonged symptoms, requiring crutches for three weeks and lasting a total of nine weeks.
  • The severity of the reaction highlights the potent nature of ratfish venom.

Implications:

  • Prompt and appropriate first aid is crucial for managing marine animal envenomations.
  • Hot water immersion is a recommended treatment for ratfish spine stings to alleviate pain and potentially denature venom components.
