We
dived in Brighton Marina in the same area (near the entrance) that the
adult Short-snouted Seahorse,
Hippocampus
hippocampus, was discovered in June,
and over a period of a few hours we spotted about a dozen juvenile Seahorses
ranging in size from 10 to 25 mm. They were not all found together. This
looks as if there is a population breeding in the marina.

are a protected species in British seas and collection for whatever reason
is illegal.

A Triggerfish,
Balistes
capriscus, was discovered washed up on Castletown
beach, near Thurso, on the extreme northerly tip of mainland Scotland.
These southern fish a now regularly seen in the English Channel but are
unusual so far north and was not immediately recognised by the local people.

Fisherman
Geoff
Blake was stunned when he discovered an unusual
30 cm long fish in his regular morning catch off Ventnor,
southern Isle of Wight. The fish was identified*
by
the fisherman as the first ever Lesser Amberjack,
Seriola
fasciata, to be found in British seas.
All four of the Amberjacks
of the North Atlantic Ocean are vagrants in British seas and there are
only 17 confirmed records of the other three species. This fish was caught
in 6 metres of water, just 200 metres from the shore.
(*Identity
to be confirmed. These fish are difficult to identify, sometimes requiring
a count of the gill rakers. Recent fish caught have been the Almaco
Jack, Seriola
rivoliana.)

A
vagrant Atlantic Tripletail,
Lobotes
surinamensis, was caught in a stake
net on
the
banks of the River Severn near Newport. The fish is now in the National
Museum and Galleries of Wales with the Curator
of Vertebrates, Peter Howlett.
This
tropical fish is likely to be the first one ever caught in British seas.
It is a sluggish offshore fish that often floats on its side near the surface
in the company of floating objects.

A number
of these contained the symbiotic amphipod
crustacean Hyperia
galba alive inside them. These are
remarkable little creatures with large green eyes, and as adults they are
only found in jellyfish.

This attractive
crab was brought in by a potter from Milford
Haven, south-west Wales. It is about 40 mm wide and is now alive and
well in the Silent World Aquarium at Tenby.
It is the species Monodaeus couchi which
is seldom recorded and may be one of the rarer crabs from the seas around
the British Isles.

A
pair of Northern Bottle-nosed Whales,
Hyperoodon
ampullatus, were washed up alive on
the Lincolnshire coast (North Sea east coast of England) and despite strenuous
attempts by the British
Divers Marine Life Rescue using pontoons to float the whales, the female
died on the scene, and the male towed 1.2 km out ot sea and seen to swim
away, was found washed up dead at Seacroft,
near Skegness, on the second day.

An
unusual discovery of a fresh but dead 27 kg (60 lb) Tuna
was found on a soft mud bank at Burry
Port, Carmarthenshire, south Wales, by
local angler Nick Roberts
and it was pulled ashore with some difficulty by
three
teenagers. The exact species is not known at present: the most likely
species is the Bluefin Tuna, Thunnus thynnus.

August 2006
A
vagrant 18 kg (40 lb) Yellowfin Tuna, Thunnus albacares
(originally identified as a Big-eyed Tuna,
Thunnus
obesus), was a rare capture by a commercial
net fisherman 70 miles off Land's End and 2,000 miles adrift of its usual
habitat in the tropical Atlantic Ocean. It
is only the second capture on record from British seas.
