These amazing creatures deserve a day, and given the name, it was always going to be in 'Oct'ober. World Octopus Day began in 2006.
Octopuses are ocean creatures famous for having eight arms and bulbous heads. Some other fun facts: They have three hearts and blue blood; they squirt ink to deter predators; and being boneless, they can squeeze into (or out of) tight spaces. They are very intelligent and have been observed using tools.
Giant Pacific octopuses are the world’s largest species and are found from Japan to Southern California. The biggest recorded specimen had an arm span of 10 metres (33ft) and weighed 270kgs (600lbs).
As well as being the largest, the giant Pacific is among the cleverest members of the cephalopod family. They also mature incredibly quickly – going from the size of a rice grain at birth to being fully grown within the space of just two years.
