The blue-ringed octopus belongs to the octopus family, commonly known as the blue-ringed octopus. Leopard octopus is widely distributed in the Pacific Ocean between Japan and Australia. It is a very small octopus species with an arm span of less than 15 cm. Can feed small fish, crabs, shrimps and crustaceans, and paralyze prey with strong toxins. In the ocean, the blue-ringed octopus is one of the highly toxic creatures, and being bitten by this small octopus will lead to death. But this octopus will not take the initiative to attack humans unless it is greatly threatened.
Most attacks on humans occur when the blue-ringed octopus is lifted from the water or stepped on. Its sharp mouth can penetrate the diver's diving suit. Female octopus needs larvae to hatch 4-8 weeks after spawning once. The young octopus looks like an adult and is very small. After hatching, it needs to drift with plankton for several weeks, and then sink to the bottom of the water for concealment.
Life habits of blue-ringed octopus
The blue-ringed octopus is shy by nature, and likes to hide under rocks and come out for food at night. If it is in danger, it will send out a dazzling blue light to warn each other. The blue-ringed octopus is a very small octopus species, and its wingspan does not exceed 15 cm. The blue-ringed octopus mainly lives in the Pacific Ocean between Japan and Australia.
The toxicity of the blue-ringed octopus can be seen from its own color. Its skin contains color cells that can change color at will. By shrinking or stretching, changing the size of cells with different colors, the overall appearance of the blue-ringed octopus will change. Therefore, when the blue-ringed octopus moves in different environments, it can use the same protective color as the environmental color.
If threatened, their blue rings will flash, hence the name "blue-ring octopus". The cells on these blue rings are densely covered with bright colored crystals formed by reflected light. The blue-ringed octopus uses these unique rings to warn other creatures that it has deadly weapons.
