About
thirty White-beaked Dolphins,
Lagenorhyncus
albirostris, were seen off the coast of
Norfolk, off the end of the Nelson Head Track, just south of Horsey Gap
on the east coast. Conditions were perfect, it was mirror calm and good
light first thing in the morning. The pod was actively fishing in association
with 4+ Porpoises, Phocoena phocoena,
and a flock of Gannets about 1000 metres offshore and appeared very settled
in the area. I watched them for one hour before I moved off. This represents
a good record of this species so far south in the North Sea.

A marine
leech, Pontobdella
muricata, was identified at a fish
merchants. The leech was approximately 130 mm in length, and was caught
aboard a vessel fishing off the Sussex coast. The catch included numerous
plaice and rays.
The relative prevalency of this leech is not known at the time of writing
but the experienced fishermen had never seen one before.
*
The literature records this leech as a parasite of rays.

Bottle-nosed
Dolphins, Tursiops
truncatus, exist along the length of the
Welsh coast and not just in Cardigan Bay as previously thought, according
to the Sea Watch Foundation's National Dolphin and Whale Watch. This one
of the results of the annual seawatching survey.

Three
visiting marine biologists found the invasive ascidian Corella
eumyota in St. Peter Port Harbour,
Guernsey, Channel Islands. This tunicate was identified by
Dr.
John Bishop from Plymouth. This southern hemisphere
sea-squirt was first discovered in Europe in Brittany in 2002.
It has now been found in marinas along the south coast of England and also
along the Channel coast of France.

Whilst
accompanying the biologists in St. Peter Port Harbour, I found many Goniodoris
castanea sea slugs with their spawn.
They were feeding on the colonial Star Ascidian, Botryllus schlosseri,
and were cryptic. On one 5 x 5 cm
square
colony of Botryllus schlosseri I found six of these nudibranchs.
Dr.
Charles David, President of La Société
Guernesiaise, tells
me this species is a new record for Guernsey.

A
large superpod of over one thousand Common
Dolphins, Delphinus delphis, were
seen off the south-west coast of Wales. The location is reported off the
Pembrokeshire coast but the exact distance from the shore is not mentioned.
The video film
footage is by Chris Benson of the Sea
Trust (the marine branch of the Wildlife Trust of South and West Wales)
is from Cardigan Bay.

Whilst
fishing the mid channel rocks near St. Anne's Head, Milford Haven, Pembrokeshire
we spotted a Sunfish, Mola
mola, at the top of the water. A couple
of seagulls were watching it which drew our attention to it. We motored
past it to see what it was, as we brought the boat around for a second
look it must have swam down as we lost sight of it. We estimate that the
fish was approximately one metre across and light grey in colour. At the
time we did not know that it was a Sunfish.

Triggerfish,
Balistes
capriscus, were in shallow water in
Long Quarry, Torquay, Devon, patrolling around in threes. We caught
two on road and line from the shore, both around a kilogram in weight.

Whilst
on board a sight seeing boat travelling back from the Island of Staffa
off the Island of Mull, Argyll, Scotland. We were on a cruise boat run
by Tarus Mara, which runs tours to Fingal's Cave on Staffa, returning to
Ulva Ferry, when we spotted a Sunfish,
Mola
mola,
swimming North West in Loch
Tuach (a sea loch).
It
was approximately one metre in diameter and seemed very healthy, turning
on it's side to watch us as we came alongside, all passengers on the boat
witnessed this unusual fish, which was icing on the cake to such a glorious
sunny summers day.

A
Leatherback
Turtle,
Dermochelys coriacea, was
found dead off the coast of Cornwall. It was spotted by a helicopter crew
which was carrying out a survey for RNAS Culdrose. The turtle, which is
the largest reptile in the world, had become entangled in lobster pot buoy
ropes off Botallack, near Land's End. It was towed to shore at Cape Cornwall
by the Sennen Inshore Lifeboat.

A
Bluefire
Jellyfish, Cyanea lamarckii, was seen in the shallows off Shoreham
Beach.
This
species has not been recorded recently off the Sussex coast although it
has been discovered in the shallow seas around the rest of Britain. It
is one of the lesser known jellyfish that frequent
the seas around the British Isles, although there have been more than the
usual number of reports from other shores this year.
