Occurrence of the physonect siphonophore Apolemia uvaria off Plymouth and in south-west England

  • Keith Hiscock (a1), Gillian M. Mapstone (a2), David V.P. Conway (a1) and Nicholas Halliday (a1)

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 water.
