A GIANT octopus which correctly predicted William and Kate would have a baby boy is set to make a series of new psychic pronouncements over the coming weeks.

Mystic Marjorie, a giant Pacific octopus at Blue Planet Aquarium in Cheshire Oaks, delighted keepers by opting for a blue baby bottle in a recent experiment to determine the sex of the royal baby.

Aquarists had provided her with two options; a pink and a blue bottle, each containing a tasty treat.

Following her successful prediction the royal baby would be a future king, staff are planning to utilise Mystic Marjorie’s psychic powers to make a series of other predictive pronouncements.

Blue Planet Aquarium’s Rebecca Collins said: “It may be a little premature to claim Marjorie as the oracle of Ellesmere Port but she’s got a 100% record so far so we’ve decided to keep going and see how good she really is.

“Several members of staff are keen to get her to pick their lottery numbers but we’re probably going to keep it simple – we may ask her to predict the result of the third test in the Ashes series which starts at Old Trafford this week and take it from there,” she added.

Giant Pacific octopus are the world’s largest species of octopus 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 also among the cleverest members of the cephalopod family. Individuals living in aquariums have been filmed sneaking out at night to raid nearby fish-filled displays.

Despite their intelligence giant Pacific octopus are relatively short lived – going from the size of a rice grain at birth to being fully grown within the space of two years.
