The octopus was found on the beach in Hornbæk north of Helsingör on Monday morning. It has a gelatinous body and bears the Latin name haliphron atlanticus, reports Helsingør Dagblad.

The animal belongs to one of the largest octopus species and usually lives at great depths in the Atlantic. The species can grow up to 3.5 meters long, but the one that has now been found is about one meter long and weighs 10-14 kilos.

The species has only been registered four times before in Scandinavia, according to Henrik Carl at the State Natural History Museum in Denmark, who has identified the octopus.

Now the octopus will be conserved in formalin to be exhibited at the Öresund Aquarium in Helsingör.

If it were to be frozen, it would be destroyed. If you freeze it and thaw it again, it would just become water and a little trash, since the body is so gelatinous, says marine biologist Kristian Vedel at the Öresund Aquarium to the newspaper.
