Additional information
Velella velella is commonly found on the surface of the warmer waters of the World's oceans (Kirkpatrick & Pugh, 1984). McGrath (1985; 1992) reported large numbers of Velella velella washed up around the west coast of Ireland each year between 1976-1984, and again in 1992. In 1981 strandings were reported along the north Cornish coast, in north Devon, Lundy, Weston-Super-Mare and south-west Wales (Turk, 1982b). The Cornish Wildlife Trust Strandings Index (2002) has reports of two main stranding events per year in the winter, December-February, and late summer early autumn, August-September.In 2002 there were numerous reports of washed up Velella velella. John White reported Velella velella washed up on a Sussex beach at Bognor rocks and Robert Harvey reported the species as far north as Kilmory Bay in the Sound of Jura (BMLSS, 2002a). Mike Bates reported Velella velella being washed up on the south of the Isle of Man, the last confirmed record previous to this was in 1954 (BMLSS, 2002a). At Millport, on the Isle of Cumbrae, Philip Smith reported small numbers of Velella velella washed ashore (BMLSS, 2002a), the first record from the Isle of Cumbrae despite there being a marine station there for over a hundred years (Smith, pers comm.). Edwards (1959) reported living specimens of Velella velella at Croy Sands, Turnberry Bay but no specimens were found on the Isle of Cumbrae despite a search.
