Blue-lined octopus
The blue-lined octopus is a small sea creature, about the size of a golf ball, that lives in shallow reefs and rock pools in the Pacific Ocean. It is one of the most dangerous animals in the sea, because its bite contains venom that can be fatal to people. It is shy and usually hides, but its bright blue lines are a clear warning to leave it alone.1

Kako ga prepoznati
- At rest, its body is mottled yellow-brown with dark blue or black streaks, and its underside is paler.1
- When it feels threatened, it shows bright, iridescent blue lines across its body.1
- It is small, with a mantle (main body) up to 45 mm long, about the size of a golf ball.1
- Its blue markings are lines, not rings.1
- The visceral hump (the bulge behind the head) is regularly pointed.1
Često se miješa s: The greater blue-ringed octopus, southern blue-ringed octopus and blue-ringed octopus have circular blue rings rather than lines. The blue-lined octopus is also the smallest of the four species in its genus.1
Otrovna snaga
Otrov izlazi kroz očnjake ili zube kad ugrize.
Što radi njegov otrov kad ugrize ili ubode?
Its venom is tetrodotoxin (TTX), a neurotoxic venom, which attacks the nerves. A bite may not be felt at first. After some time, symptoms include loss of feeling in the tongue and lips, muscle weakness or paralysis, respiratory failure (breathing failure), and unconsciousness, which can lead to death.1
Koliko je opasno za ljude?
Opasnost za ljude: SmrtonosnoJedna od najopasnijih životinja na svijetu.It is regarded as one of the most dangerous animals in the sea, and its venom can be fatal to humans. At least three human deaths have been reported. The greatest risk is to people who pick it up or touch it.1
Što radi kad se uplaši?
When threatened, it displays bright blue warning lines to predators, and it is more likely to flee and hide in shelter than to fight.1
Ako ugrize
- Imobilizacija pritiskom: čvrsto omotaj elastični zavoj preko ugriza, a zatim uz cijeli ud, stavi udlagu i drži osobu potpuno mirnom dok ne stigne pomoć.
- Plavoprstenasta hobotnica ili stožasti puž mogu zaustaviti disanje osobe dok je još pri svijesti: pozovi pomoć i budi spreman davati umjetno disanje dok hitna pomoć ne preuzme.
Uvijek prvo nazovi broj za hitne slučajeve (112, 000, 911). Ovo su opće upute za prvu pomoć, a ne liječnički savjet. Osnove prve pomoći
Ostani na sigurnom
- Nikad ne diraj, ne hvataj i ne zadirkuj divlju životinju, čak ni malu, i čak ni ako izgleda kao da spava ili je mrtva.
- Ostavi joj prostora. Ako je sretneš, ne paniči, polako se odmakni i pusti je da ode svojim putem.
- Ako te neka ugrize: ne paniči, miruj, nazovi broj za hitne slučajeve (112, 000, 911) ili brzo idi u bolnicu. Zapamti kako je izgledala, fotografija pomaže.
Ne želi ti ništa loše. Otrov koristi za lov hrane ili za obranu i mnogo bi se radije sakrilo. Više o sigurnosti

Činjenice
A single 25-gram blue-lined octopus carries enough venom to kill about ten adults weighing 75 kilograms each, according to estimates.1
Male blue-lined octopuses bite the female's aorta during mating, injecting TTX. This paralyses her within about 8 minutes, which lets the male transfer his sperm packets safely.1
Hapalochlaena is the only octopus genus known to produce TTX, a toxin thought to have played an important role in the evolution of the species.1
The blue-lined octopus is the only one of the four blue-ringed species with lined blue markings instead of circular ones.1
Blue-lined octopuses are nocturnal hunters, while the greater blue-ringed octopus hunts during the day.1
Its range has been spreading across the Pacific. Warming ocean water may be shifting suitable habitat, and scientists monitor this for public health and safety.1
Razbijač mitova
Mit: Because it is so shy, the blue-lined octopus is not really dangerous.
Istina: It is extremely shy and usually flees, but its venom can still be fatal to people, and at least three deaths have been reported.1
