In September 2007, observations were made of a siphonophore in surface waters and near to the seabed by sea users off south
Devon and south-east Cornwall. The same siphonophore was also recorded from regular samples collected offshore of
Plymouth. The species is identified as Apolemia uvaria, which had not previously been recorded off Plymouth. It was
sampled until March 2008 and re-appeared, in smaller numbers, in autumn 2008 until February 2009 but was not reliably
reported in autumn 2009 (to end of October). The occurrence is unlikely to be due to sea warming, but more likely some variation
in oceanic currents, possibly influxes of Atlantic wate
