A
post storm check of Thurlestone (south Devon) beach for stranded cetaceans
or oiled birds revealed my first ever UK sittings of by the Jack-by-the-Wind-Sailors,
Velella
velella, several hundred, some as just the chitinous float and
sail. I have never noticed them before in Britain but I saw millions on
beaches in SW Corsica last May. There was no sign of the predatory Violet
Sea Snails,
Janthina sp., often
(rarely in the UK) associated with this creature or tropical
seeds but three species of Cuttlefish
were present in reasonable numbers.
Lots
of Large (Turban) Topshell, Gibbula
magus, and Necklace (Moon) Shells Polinices
sp. were washed up on Slapton Sands, Devon.

A
juvenile Bottle-nosed
Dolphin, Tursiops truncatus, was
discovered on a remote north Cornish beach at Gwithian,
near Hayle. This is unusual as it is usually Common
Dolphins,
Delphinus delphis, that are
washed up, often killed in fishing nets with a total of 220 recorded in
2004.
In
this case it seemed to be heavily scarred with fresh "rake marks", wounds
inflicted by the sharp teeth of one or more other dolphins, which may have
attacked the individual. This behaviour has been seen in Bottle-nosed
Dolphins off America.
It
is not known why they occasionally attack one another but fatalities appear
to be
confined
to fights between males. If the post-mortem confirms that this was the
case, it will be the first recorded incident of its kind in the UK.

A
Sunfish,
Mola
mola, was washed up on the beach at West Runton, near Sheringham,
north Norfolk.
Although
this fish is frequently seen off the south and western coasts of Britain
during the summer and autumn, sightings and strandings in the North Sea
are much less common.

There
are at least a dozen reports of at least 16 Triggerfish,
Balistes
capriscus, being found washed up dead on
Cornish beaches, and these are probably only a fraction of the actual strandings.

were also dead Triggerfish

A
pod of seven White-beaked
Dolphins, Lagenorhyncus
albirostris, off Dungeness, Kent. They
gave a spectacular display including leaping clear of the water as they
fed and were in view for most of the afternoon. I have looked at the sea
on an almost daily basis at Dungeness since 1989 and this is the first
time I have seen White-beaked Dolphins.
NB:
This species of dolphin is not often recorded in the eastern English Channel.

Commercial
fisherman Andy Le Prevost
trawling on the Lady Patricia caught a Almaco
Jack, Seriola rivoliana, (originally
identified as a Guinean Amberjack,
Seriola carpenteri), on the south-west Casquet bank, near
the Channel Islands, at night.
ID
Details
The
fish was caught at a water depth of 25 metres. The fish was small (length:
30.7 cm, weight: 637 grams) and similar in size to the specimen caught
by George Staples
east of Herm Island on 7 September 2000.
The sea temperature was 11.7°C. My records indicate that this is the
fourth confirmed Amberjack
species caught in Channel Island waters.

A
40 cm long Oriental Flying Gurnard, Dactyloptena
orientalis, was hauled up in a herring net less than a mile from Penzance.
The fish is being kept at the Blue Reef Aquarium
in Newquay after
skipper Tony Richards,
from St. Ives, kept it alive.

“We
were in only about 15 metres depth and were hauling up our herring nets
by hand. It was the last fish in the net. I could feel by touching that
it was an extraordinary specimen — its skin is armoured. It had a flat
head and when I picked it up it spread its wings. They are as wide as the
fish is long, about 40 cm.
“It
is a beautiful animal. Its wings are all different colours: blue, red,
yellow and grey. I’ve never seen anything like it in all my years at sea.
It’s an incredible beast.”
This southern
species of gurnard has only been recorded on one or two occasions off British
coasts, both if them off the coast of Cornwall.

Guernsey
commercial fisherman Steve Fallaize
landed a handsome Couch's Sea Bream,
Pagrus pagrus, on weighing 2688 grams whole (5.93 lb). The fish
was netted in a water depth of about 20 to 25 metres over a mixed shell-gravel
bottom off Guernsey's west coast. This is the largest Couch's
Sea Bream that I have recorded in Guernsey.
Small
Couch's Sea Bream have been frequently landed
in recent years around the Channel Islands, but this is a southern fish
and it is uncommon any further north.

Red
Sea Bream were common during the 1970s but
disappeared from his catches after 1984. Black
Sea Bream were also almost completely absent
from his angling catches during the 1980s but have, in the last five years,
made a spectacular comeback.
