They have blue blood, three hearts, jet propulsion and can change shape. And they are right here in the heart of Southsea.
Don’t panic. We’re not announcing an alien invasion, but a celebration of certain sea creatures at Blue Reef Aquarium.
The cephalopod family, literally ‘head foot’ in Greek, includes octopus, squid, nautilus and cuttlefish.
For short, Blue Reef just call them ‘suckers’ and they are being celebrated and scrutinized in a special event over half-term.
With all the above traits fact, not fiction, it’s little wonder these suckers have inspired myths and legends since the dawn of time.
From tomorrow until Sunday, February 27, families can learn all about these amazing animals.
Suckers Week includes an octopus quiz trail around the aquarium and a series of special themed talks and activities.
Star of the show will be the aquarium’s giant Pacific octopus, Lucy, who has a tentacle-span of more than two metres.
These creatures are the world’s largest species and are found from Japan to Southern California.
The biggest recorded specimen had an arm span of eight metres and weighed 71kgs.
Despite being closely related to the garden slug (yes, really), octopus are believed to be as intelligent as pet dogs and can solve complex puzzles.
This has been proven in Southsea by Lucy, who recently solved a series of specially-designed puzzles.
Most octopus can also rapidly change body shape, texture and colour. And it is believed that some species use this ability to communicate basic emotions – like fear and anger.
They can even change to blend in with their surroundings, sometimes so effectively that they become invisible.
With no skeleton, they can squeeze their bodies through the tiniest of gaps.
And, when all else fails, octopus produce their very own ‘smoke screens’ or body doubles made out of ink to confuse attackers.
Out of this world!
