  • Conservationists have declared 2025 the 'year of the octopus' following record sightings of the common octopus in British waters.
  • The Wildlife Trust reported the highest numbers of octopus vulgaris since the 1950s, particularly in south Cornwall and Devon.
  • This significant increase is attributed to rising sea temperatures and a warm breeding season, which has led to greater larval survival.
  • Approximately 233,000 octopuses were caught by local fishers in Cornwall, representing about 13 times the usual amount.
  • The charity anticipates even higher numbers in 2026 due to predicted global temperature rises and suggests fisheries may need to adapt as octopuses prey on shellfish.
