The Bay of Bengal blue-ringed octopus is a small sea creature that hides in rock crevices and coral reefs. It is one of the most venomous marine animals in the world, even though it is only about the size of a hand. Its blue rings are a warning to keep away.1

Kekuatan bisa

Gigitan

Bisanya keluar lewat taring atau gigi saat menggigit.

Apa efek bisanya?

Its venom contains tetrodotoxin, a neurotoxin (a poison that attacks the nerves). It causes paralysis of the muscles and can stop breathing within minutes. Victims stay fully aware but cannot move, and the venom can also cause nausea, heart failure and blindness.1

Seberapa berbahaya bagi manusia?

Bahaya bagi manusia: Sangat berbahayaBisa membunuh orang yang tidak diobati.

The octopus carries enough venom to kill more than 20 adult humans within minutes. Its bites are tiny and often painless, so victims may not realise they have been bitten until breathing problems and paralysis begin. Estimates of recorded human deaths range from seven to 16, and most scholars agree at least 11 have occurred. Children are the most at risk because of their small body size.1

Apa yang dilakukannya saat takut?

It first tries to flee. If the threat continues, it takes a defensive stance and flashes its blue rings, and if cornered and touched it may bite.1

Jika ia menggigit

  • First aid is pressure on the wound, followed by artificial respiration as soon as paralysis stops the victim breathing. Respiratory support should continue until medical help arrives. In hospital, the patient is put on a ventilator until the toxin leaves the body, and those who survive the first 24 hours usually recover completely.1
  • Imobilisasi dengan tekanan: balut gigitan dengan perban elastis yang kencang lalu lanjutkan ke seluruh anggota tubuh, pasang bidai, dan jaga orangnya benar-benar diam sampai bantuan datang.
  • Gurita cincin biru atau siput kerucut bisa membuat orang berhenti bernapas padahal ia masih sadar: minta bantuan dan bersiaplah memberi napas buatan sampai ambulans datang.

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 ia menggigitmu: 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

Fakta

1

The blue-ringed octopus was the first animal reported to use tetrodotoxin as a venom. The same toxin is also found in pufferfish, rough-skinned newts and some poison dart frogs.1

2

The mother may inject the toxin into her eggs, which may then make their own venom before hatching.1

3

The octopus produces its venom using bacteria living inside its posterior salivary gland.1

4

Its blue rings flash in less than a third of a second, using muscles under nerve control. This is a warning display.1

5

The octopus's own body is resistant to its tetrodotoxin, so the venom does not harm it.1

6

In the 1983 James Bond film Octopussy, the blue-ringed octopus is the symbol of a secret order of female bandits and smugglers.1

Pembongkar mitos

Mitos: Because it is small and relatively docile, the blue-ringed octopus is harmless.

Faktanya: It is small and usually calm, but it is very dangerous if it is provoked or handled. Its venom can kill a healthy adult within minutes if not treated.1
