The greater weever is a small sea fish that buries itself in shallow sand along the eastern Atlantic coast and in the Mediterranean and Black Seas. Its spines carry a venom that causes intense pain, so it is one of the most dangerous fishes in the Mediterranean for swimmers.1

Duri berbisa

Duri tajam membawa bisa. Memijak atau memegangnya menyakitkan.

Apa kesan bisanya?

The venom contains a large protein called Dracotoxin, which can be lethal in high enough doses. It damages cell membranes, and the sting is followed by a short period of tissue changes around the wound. The best-known effect is excruciating pain that begins shortly after the sting and can last from a few hours to days.1

Berapa bahaya ia kepada manusia?

The most common incident happens when a bather steps, jumps or falls onto a buried greater weever in shallow water, especially in summer. Fishermen handling fish caught in nets are also at risk. The pain can reach 10 out of 10 on the numeric rating scale, and some stings have caused pain for months, though this is rare. Reported fatal accidents exist, but these are widely believed to be due to secondary infections and sepsis rather than the toxin itself.1

Jika durinya menikam kamu

  • Rendam luka dalam air panas, sepanas yang orang itu boleh tahan tanpa melecur (uji dengan tangan kamu sendiri), selama 30 hingga 90 minit. Dapatkan bantuan perubatan, terutamanya untuk ikan batu dan ikan pari.

Sentiasa hubungi nombor kecemasan dahulu (112, 000, 911). Ini panduan pertolongan cemas umum, bukan nasihat perubatan. Asas pertolongan cemas

Kekal selamat

  • Jangan sesekali sentuh, tangkap atau usik haiwan liar, walaupun yang kecil, dan walaupun ia nampak tidur atau mati.
  • Beri ia ruang. Jika kamu terjumpa, bertenang, undur perlahan-lahan dan biarkan ia pergi.
  • Jika durinya menikam kamu: bertenang, jangan bergerak, hubungi nombor kecemasan (112, 000, 911) atau pergi ke hospital dengan segera. Ingat rupanya, gambar boleh membantu.
