Sea urchins in Israel, Diadema setosum (Red Sea) and Paracentrus lividus (Mediterranean), cause painful injuries when stepped on. Their brittle spines and venom lead to mechanical damage, foreign body reactions, and potential infection.

Area of Science:

  • Marine biology
  • Toxicology

Context:

  • Sea urchins are prevalent along Israeli coasts, with distinct species dominating the Red Sea (Diadema setosum) and Mediterranean (Paracentrus lividus).
  • Injuries from sea urchins are a common concern in coastal regions.

Purpose:

  • To describe the types of injuries caused by common sea urchin species in Israel.
  • To outline the clinical presentation and complications of sea urchin envenomation.

Summary:

  • Sea urchin injuries are primarily mechanical, resulting from penetration by brittle spines.
  • Envenomation involves venom secreted by epithelial tissues, causing severe pain, edema, and local sensory loss.
  • Complications include foreign body reactions to spine fragments and epithelium, and secondary infections (suppuration).
