A family of fishes with a body encased in a hard armour. This means that they use the dorsal fin as a means of propulsion. The seahorses use the dorsal fin exclusively for swimming and the pipefishes use it for slow movements, with the pectoral fin vibrated to keep the fish steady, but the pipefish are able to wriggle their long slim bodies (the extent varies between species) to escape predators.
In this family only, the males incubate the eggs in a groove or a fold, and in the seahorses they are kept within a brood pouch.
The
family usually inhabit the shallow seas, but some live deeper than 30 metres,
and a few species are pelagic
(i.e.
live in the surface waters of the open ocean).
NEW BOOK
Neil Garrick-Maidment runs the Seahorse Nature Aquarium in Exeter, (now moved to the National Aquarium at Plymouth), and he passes on his knowledge of keeping and breeding them in captivity in this small book. The most important snippet of information is on page 15 when it says that adult seahorses eat about 40 mysid shrimps a day.
"Every year, huge numbers of seahorses die
in aquaria as a result of the lack of accurate information on
how to keep them. This book redresses the
balance by giving a comprehensive account of how to care for
these most difficult of marine fish, but
also stresses the need for conservation in the wild".
Feeding live food to seahorses is more likely than not to be an insurmountable
problem for the home aquarist, and anybody wishing to keep this fish will
need to buy this book. If you are just interested in these fascinating
fish the 48 page book contains information not published elsewhere.
Greater Pipefish, Syngnathus acus.
Very common, widespread.
Aquarium Study of the Greater Pipefish
Lesser Pipefish, Syngnathus rostellatus. Very common, widespread.
Deep-snouted Pipefish, Syngnathus typhle. Local, frequent.
Straight-nosed Pipefish, Nerophis ophidion. Local, uncommon on the shore.
Worm Pipefish, Nerophis lumbriciformis. Very common in the south and west only. Unknown from the east coast.
Snake Pipefish, Enterulus aequoreus. Uncommon, west coast only, frequent in some areas.
Seahorse, Hippocampus ramolosus. Rare in English Channel, Dorset
and western approaches only.
Now Hippocampus
guttulatus
Short-nosed Seahorse, Hippocampus hippocampus. Occasionally found in deep water around the Channel Islands. Extremely rare, probably absent elsewhere. Also recorded off the coast of Holland in 1998.

All Seahorses are a protected species in British seas and collection for whatever reason is illegal.
My
basset
dog found a Short-snouted
Seahorse,
Hippocampus
hippocampus, just
east of Splash Point (east of Worthing Pier) on Worthing
beach. Although it was dead and slightly smelly, it was intact. The
Seahorse
was found at high tide.

Another
Short-snouted
Seahorse,
Hippocampus
hippocampus, was discovered washed up
on the strandline, near Brighton Pier (=Palace
Pier) by beginning of Volk’s Railway (TQ 315038).
The
discoverer was a Mr J Chapman.

A
Sea
Horse, Hippocampus sp., was
spotted and collected in a bucket by Edward
Wilson (aged 8) near the entrance of the outer
harbour of Brighton Marina, Sussex. The adult fish of an estimated height
of 150 mm (6 inches) was seen to swim away in a healthy condition. The
identification was confirmed by a photograph.
Sea
Horses were regarded as rare from the seas
off Sussex until this year.

An
extremely interesting report of three Sea
Horses, Hippocampus hippocampus*
reported
by Southwick (West Sussex) fishermen; the fishermen
say they are the first caught for several years and other fishermen are
reporting them in their fixed nets several miles offshore. The
identity of these fish has not been verified personally, but Sea
Horses are known to be rarely captured from
the Sussex coast.
(*The
species, one of two, is not known.)

A
Whiting
was caught on rod and line four miles out of Brighton, Sussex, and it promptly
regurgitated a Seahorse,
Hippocampus
sp. Seahorses are not known off the Sussex coasts, although I have received
at least one unconfirmed sighting before. This is probably the Short-snouted
Seahorse, Hippocampus hippocampus.
(It is usually the shallow water species Hippocampus
guttulatus that has been recorded off
the Dorset coast.)

A
pregnant male Seahorse,
Hippocampus
guttulatus, was discovered and photographed
in Poole Bay, Dorset. This is the first recorded instance of a pregnant
Seahorse
in the northern English Channel and anywhere in the seas surrounding the
British Isles and is therefore the first confirmed instance of successful
breeding, which has long been suspected. Discharge of the young into the
shallow sheltered ways of Poole Bay seemed imminent.

Late November 2002
A Short-snouted Seahorse, Hippocampus hippocampus, is captured by an oyster fisherman in the Solent. In Victorian times, there are records from off Dorset and the Solent.
Late August 2002
Three specimens of the Short-snouted Seahorse, Hippocampus hippocampus, were discovered about 95 miles east of the Solent in the English Channel. They were picked up during DEFRA sponsored fish habitat studies by the University of Wales Bangor research vessel Prince Madog. Each came up in separate gear deployments, though at a single sampling station. On UWTV the benthic biotope where they came from was seen to be sand with a dense bed of tube worms, Lanice conchilega. All three seahorses were "pregnant" males.Report by Ivor Rees

There
have been further reports of Short-snouted
Seahorse, Hippocampus
hippocampus, from around the Channel Islands. Fisherman Steve
Ryall hauled them up in his nets together
with Lumpsuckers and large Soles over 3 kg in weight. The Seahorses were
returned alive. Lobster and crab fisherman Andy
Egre reports catching two large Seahorses
in his pots about a mile and a half off Rozel in 30 metres of water in
an area of strong tides.
The Marine and Estuarine Fishes of Wales shows confirmed records of the Seahorse Hippocampus guttulatus (=H. ramulosus) in north Cardigan Bay, Pembrokeshire and the Severn Estuary! I would be extremely interested to hear from you if you find any!!!
You could also try looking in the Seagrass beds at Port Dinllaen (which appear to survive being in a mooring area so I can't see a few divers causing any damage). Also Shell Island just south of Harlech could be a good shore dive for looking for them - very shallow and weedy, quite interesting at times but varies too.
Thanks.

Hippocampus.
guttulatus.
This is still known as Hippocampus guttulatus (=H. ramulosus)
until the identification and renaming has been approved in Switzerland
by the nomenclature society.
They start to breed at about 6 months but are seasonal.

The other suborder in the Order is the Aulostomoidei.
I think the Snipefish, Macrorhamphosus scolopax, is included
in this Order.
In the books the Syngnathidae
are usually placed after the Dories (Zeiformes) and before the Sticklebacks
(Gasterosteiformes).
However, this may have changed
recently. AH 2000
