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

Kekuatan bisa

Duri berbisa

Duri tajam membawa bisa. Menginjak atau memegangnya terasa sakit.

Apa efek 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

Seberapa berbahaya bagi 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 menusukmu

  • Rendam luka dalam air panas, sepanas yang masih bisa ditahan tanpa melepuh (coba dulu dengan tanganmu sendiri), selama 30 sampai 90 menit. Cari bantuan medis, terutama untuk ikan batu dan ikan pari.

Selalu hubungi nomor darurat dulu (112, 000, 911). Ini panduan pertolongan pertama umum, bukan nasihat medis. Dasar-dasar pertolongan pertama

Tetap aman

  • Jangan pernah menyentuh, menangkap, atau mengganggu hewan liar, walaupun kecil, dan walaupun tampak tidur atau mati.
  • Beri ia ruang. Jika bertemu, tetap tenang, mundur perlahan, dan biarkan ia pergi.
  • Jika durinya menusukmu: tetap tenang, jangan bergerak, hubungi nomor darurat (112, 000, 911) atau segera ke rumah sakit. Ingat seperti apa rupanya, foto sangat membantu.

Ia tidak mengincarmu. Ia memakai bisanya untuk menangkap makanan atau melindungi diri, dan ia jauh lebih suka bersembunyi. Lebih lanjut tentang tetap aman
