Dear SCUBA News

I was diving in San Rafael, France last summer and would 
like to go back again. However, I can't remember the name 
of the SCUBA place. It was in a campsite - can you suggest 
its name and if they have an e-mail address?  Also where 
is the best spot for diving in St. Raphael?

Thanks

Carla

news@scubatravel.co.uk and we'll pass it on.

Creature of the Month: The Octopus
===================================================

The octopus is found all over the world: in warm and cold 
water, in deep oceans and in the shallows. It is an 
invertebrate, having no backbone, but is extremely 
intelligent. Unfortunately an octopus lives only two or 
three years.

Octopus solve problems by experience and trial and error. 
Once it has solved a problem, it remembers and can solve 
the same type of problem in the the same way but faster 
each time. For example, an octopus soon learns to 
unscrew jars to remove food placed inside. 

Octopus tend to spend the day inside holes.  Once you get 
an eye for it, you can spot their lairs by the pile 
of stones concealing the entrance, and crustacean remains 
nearby.

The octopus normally lives alone. When mating occurs, the 
smaller male stretches out a modified arm to the female. 
The arm has grooves along which parcels of sperm pass. 

The female octopus guards her eggs, hosing them with 
water to keep them clean and aerated.  In some species 
she might not eat during this time and die soon 
afterwards.  Some males don't fare any better, as they 
may be eaten by the female after mating.

Sharks, moray eels and seals all prey on octopods.  One 
escape strategy is to squeeze through the tiniest of gaps 
into crevices.  Others include camouflage - their skin 
changes colour and texture to mimic their surroundings - 
and ink squirted at the predator.

All octopus can inject their prey with venom, but some, 
notably the Australian blue ringed varieties, are 
extremely poisonous to humans.  Their venom paralyses 
muscles.  Mouth-to-mouth resuscitation will keep people 
alive until the venom wears off, 24 hours later.  The 
victim is fully aware of what is happening around them, 
but is unable to move or breath.

Choosing Sea-Sickness Medication 
================================

This article is by the UK Sport Diving Medical Committee.  
Their information is regularly updated: in future please 
refer to 
http://www.uksdmc.co.uk/
for the latest version.

  The problem with sea-sickness medication is that some 
  tablets may make you drowsy and may therefore predispose 
  you to nitrogen narcosis. 

  It is strongly advisable to find the medication which 
  best suits your body.  First, you should purchase a type 
  recommended by your local pharmacist (such as Stugeron), 
  and take a test dose at a time when you are not driving 
  or diving.  If you become drowsy, you will know the 
  medication does not suit you and you must then try 
  another type.  This procedure should be repeated until 
  you find one which does not make you drowsy. It is 
  important to note that the one which suits you best 
  might not suit your buddy at all.  This is nothing to 
  worry about and is due to differing body metabolism. 

  Your initial dives on this medication should be 
  shallow. Depth should be gradually increased over 
  subsequent dives in order to minimise the possibility 
  of adverse effects on a deep dive.  Beware of the 
  possible additive effects of this medication with 
  prolonged use.  If any drowsiness is experienced, 
  you should not take a dose on that day. 

  At the start of a new diving season, prior to diving, 
  it is advisable to retest yourself in this way to 
  ensure that your chosen medication still suits you.

DIVE SHOP SUED FOR TRYING TO PROTECT SHARKS
  A dive shop is being sued over a pamphlet claiming a 
  fishing charter is guilty of the needless killing of 
  Zambezi sharks and that the fishing has significantly 
  reduced the shark population in the area.

LACK OF SHARKS WORRIES BRITISH TEAM
  An expedition to find a great white shark in British 
  waters has ended without success.  More worrying was 
  the lack of native species.  "I would liken our trip 
  to going to a game park and discovering that someone 
  had killed all the mammals."

COMMENTS WANTED ON SEAHORSE PROTECTION
  The New South Wales Government (Australia) is inviting 
  comments on proposed protection measures for a unique 
  family of fish that includes seahorses, pipefish, 
  pipehorses and sea dragons. The closing date for 
  submissions is 26 September 2003.

REEF DECLINE NOT NECESSARILY NEW
  Global warming and pollution are among today's threats 
  to coral reefs, but new research shows the problem began 
  started when people first began killing off top predators 
  and large herbivores - a process that started thousands 
  of years ago in some places and just a century or so ago 
  in others. The Great Barrier Reef sometimes is said to 
  be largely pristine, but it's actually as much as a 
  third of the way toward ecological extinction!  The 
  research gives custodians of the world's coral reefs 
  a yardstick they can use to determine how far their 
  particular reef system has progressed along the 
  ecological "extinction continuum."
