It is common in the Irish Sea. It typically is up to 40 cm (16 in) in diameter, but can exceptionally reach 90 cm (35 in), making it the largest jellyfish in British waters (Cyanea capillata reaches an even larger size, but is generally smaller in Britain).

It is a favourite food of the leatherback turtle.
