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

Fakta

1

A single 25-gram blue-lined octopus carries enough venom to kill about ten adults weighing 75 kilograms each, according to estimates.1

2

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

3

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

4

The blue-lined octopus is the only one of the four blue-ringed species with lined blue markings instead of circular ones.1

5

Blue-lined octopuses are nocturnal hunters, while the greater blue-ringed octopus hunts during the day.1

6

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

Pembongkar mitos

Mitos: Because it is so shy, the blue-lined octopus is not really dangerous.
