Wilderness: Scorpionfish, Lionfish, and Stonefish Topic Guide
Scuba Diving: Scorpionfish, Lionfish, and Stonefish Poisoning: Scorpionfish, lionfish, and stonefish are all poisonous marine animals that live in tropical and temperate oceans, especially the Red Sea and Indian and Pacific oceans. Each of these fish have poisonous erectile spines on their dorsal, anal, and pelvic fins. Encounters with these fish is generally accidental. The fine poisonous spines are covered in a mucous-containing poison that can cause mild to severe reactions. Symptoms of poisoning from these fish include intense throbbing and pain, redness, bruising, edema, numbness, tingling, blisters, numbness, and tissue shedding at the sting site. Treatment is immersion in hot water, local pain blocks, tweezers to remove any spines, washing the wound site, and possibly, medical treatment and a tetanus booster.
Rash A rash is a visible skin outbreak. Examples of noninfectious rashes include eczema, psoriasis, contact dermatitis, seborrheic dermatitis, rosacea, hives, and allergic dermatitis. Types of infectious rashes include ringworm, impetigo, scabies, herpes, chickenpox, and shingles. Rashes may be caused by fungi, viruses, bacteria, and parasites. Treatment depends upon the type of rash.
