Swordfish

Andrew Johnson, from the University of Glasgow, spotted a two metres long
Swordfish, Xiphias gladius, five miles out of the Firth of Lorne in September of
this year. On a beautifully calm day with the Atlantic like a millpond, he spotted
something rising out of the water and coming straight towards the boat. He
could not believe his eyes, but with a long sword about a third the length of its
body, he identified it as a species of swordfish. To his surprise, it rose a further
seven times in full view of the divers on the charter boat heading for a site west
of the Garvellachs.

The Swordfish is the only member of the family Xiphiidae. It has a long pointed
snout which it uses to stun fish on which it will then feed. This fish is a
widespread and solitary fish throughout the warmer oceans, but it is an
extremely rare vagrant in British seas. One specimen was seen off the south of
the Isle of Wight a couple of years ago.

The Swordfish, Xiphias gladius, has a tuna-like first dorsal fin and attains a
length of 4.9 metres. Specimens are usually between 2 and 3 metres in length. It
feeds on shoaling fishes and squids. Its colour on the most often seen upper
surface is a blue-grey, paler underneath.

The only other fish recorded in British seas with a pointed snout is the Sailfish,
Istiophorous platypterus, which is distinguished by a huge dorsal fin. This latter
species has only been recorded once stranded on a Devon coast in 1928
(A. Wheeler). This fish belongs to the family Istiophoridae, which includes at
least three species of marlins and spearfishes with pointed snouts.

The Firth of Lorne is the six mile wide passage between the mainland and the
Isle of Mull and there is an open stretch of water to the Atlantic.

Seals

In the summer of 1993, Susanne Herbert spotted a seal in the sea off Shoreham-by-Sea, a
most unusual occurrence.

In July 1996 a one and a half year old Grey Seal hauled up on a wooden support underneath
the footbridge that crosses the River Adur in the centre of the Sussex town of
Shoreham-by-Sea. It remained there until it swam back out to sea with the receding tide.
