Unprecedented sightings of a supremely intelligent sea creature over the summer months have prompted the declaration of 2025 as the year for octopuses in a yearly report of the nation's marine environment. A Perfect Storm Driving a Surge A gentle winter coupled with an exceptionally warm spring triggered a huge population of *Octopus vulgaris* to establish themselves along England’s south coast, across the southwestern peninsula. “The reported landings was approximately over a dozen times what we would typically see in the waters around Cornwall,” stated a marine life specialist. “Calculating the figures, nearly a quarter of a million octopuses were found in British seas this year – that’s a huge increase from the norm.” The Mediterranean octopus is found in British seas but ordinarily in such small numbers it is infrequently encountered. A population bloom is caused by the dual effect of gentle winter conditions and favorable spring temperatures. These ideal conditions meant a higher survival rate for young, potentially supported by large numbers of a favored prey species seen in the area. An Uncommon Occurrence The most recent occasion, a population surge of this scale of this size was recorded in the mid-20th century, with archival data indicating the one before that occurred in 1900. The huge numbers of octopuses meant they could be readily observed in nearshore environments for a rare occurrence. Video footage show octopuses gathering in groups – contrary to their normally lone nature – and moving along the bottom on their tentacle tips. A curious octopus was even filmed grabbing an underwater camera. “The first time I dived off the Lizard peninsula this year I saw multiple octopuses,” the specialist continued. “They are sizeable. Two kinds exist in these waters. One species is smaller, football-sized, but the *Octopus vulgaris* can be reaching impressive sizes.” Predictions and Marine Joy If conditions remain mild this coming winter suggests the potential a second bloom next year, because historically, under these conditions, the blooms have repeated for two consecutive years. “However, it is unlikely, looking at history, that it will go on for a long time,” they said. “Marine life is unpredictable these days so it’s hard to forecast.” The assessment also celebrated other “surprises, successes and joyful moments” across British shores, including: Highest-ever counts of grey seals seen in one northern region. Exceptional populations of puffins on an island off Wales. A first-ever sighting of a rare sea slug in Yorkshire, usually found in the south-west. A type of blenny discovered off the coast of Sussex for the inaugural time. Not All Positive News Challenges were also present, however. “The calendar year was marked by environmental disasters,” stated an expert. “A major tanker collision in March and the release of plastic pollution off the Sussex coast were serious issues. Staff and volunteers are working tirelessly to defend and heal our coasts.”
