juvenile male calf, but still massive, Humpback Whale, Megaptera
novaengliae, weighing 8 tonnes with
a length of 7 metres, was found dead floating close to shore at at Fishnish
on the Isle of Mull.
It was craned on to the shore for a post-mortem. Even at this size, it
was dependent on its mother for nutrition. This
was probably the first ever Humpback Whale washed up on Mull.
numbers of Bluefire Jellyfish, Cyanea
lamarckii, were spotted on the falling
at Padstow in north
of the more interesting characteristics of this very wet spring were the
numerous reports of very large jellyfish washed
up on the southern and western shores of Britain. Almost all of them were
the non-venomous Barrel Jellyfish, Rhizostoma
octopus. Reports were received from
all south-western coasts and many of them were seen in the sea and washed
up on the shore of Dorset.

blue specimen was a typical sized specimen as others were reported the
size of dustbin lids. This was washed up at the Witterings,
West Sussex. The most usual colour of this jellyfish is a creamy wide umbrella
with trailing tentacles of cream and sometimes brownish-red.
and scavenged Tuna was found washed up in the Fleet, Dorset. The
fish was in too worn condition to identify it to species. Tuna
are an uncommon visitor in summer in the English Channel.
Scorpion Fish, Scorpaena
was captured in pots off Plymouth. This benthic
southern species is only rarely recorded in British seas. It is the spines
on this bottom living predator that are venomous and in the Mediterranean
Sea and the Atlantic coast of Portugal it is a hazard to bathers.
day with friends from Coastwise
North Devon at Westward
produced a special find: a little Sand
was caught in a push net at the edge
of the sea.
Pegusa lascaris, was a particularly
interesting discovery as this is a southern species and it is not often
recorded in British seas. I do not know if this a rare
in British seas or just rarely recorded?

immigrant Asian Shore Crab,
was discovered by Martin
Burke in a rock
pool by the Aberthaw
Power Station, in south Wales. This small
crab is a species of crab from
East Asia. It has been introduced to several other shores, and is now an
invasive species in North America and Europe. These crabs are known from
the European mainland and have been reported in Guernsey,
as far as we are aware this is the first
record of Hemigrapsus
on mainland GB and is therefore a significant record. Asian
Shore Crab larvae are thought to have been
introduced to European waters through discharge of ships’ ballast water.
It has since extended its range through natural larval dispersal by water
currents. It is unclear how it reached the Channel Islands, but given
the proximity of the abundant populations on the French coast, natural
larval dispersal, hull fouling and association with oyster transportation
We originally identified it as the immigrant Marbled
Rock Crab, Pachygrapsus

discovered on Newquay Beach,
north Cornwall, was discovered to be hosting Goose
Barnacles, Lepas anatifera,

that had burrowed into the shell. These were identified as the vagrant
