Shark attack suspected in swimmer's disappearance

Police in Perth say experts believe missing swimmer Bryn Martin was taken by a white pointer shark at Cottesloe Beach. The 64-year-old Mosman Park man set out from the shore near the Indiana Tea Rooms on his daily swim on Monday morning. He was heading out to a buoy several hundred metres from the shore when he disappeared from sight. A friend and several other swimmers went into the water looking for Mr Martin but could find no sign of him.

Senior Sergeant Denise Grant says several hours later, police divers found Mr Martin's bathers on the sea bed near the buoy.

"Police divers have located a pair of black speedo bathers that have been positively identified by our missing person's wife," she said.

Police say fisheries experts have viewed the bathers and say the damage to them is consistent with that which a white pointer shark would cause.

Senior Sergeant Denise Grant says Mr Martin's friend quickly alerted authorities.

"He comes down with a friend and his friend was waiting on the beach and he saw him swimming out there, and then he's gone to enter the water and then he couldn't see him anymore," she said.

"He was a very strong and a very good swimmer apparently."

Mr Martin's family spent the day at the beach waiting for developments.

The skipper of a Whitfords sea rescue boat involved in the search, Mike Walters, has told the ABC it was thorough.

"It was fairly intense and there were a couple of helicopters in the air and the police helicopter was there for a very long period of time, so they gave it the best chance," he said.

Police, surf lifesavers and SAS troops from the nearby barracks spent the day searching the water and foreshore for the man. Police media's Graeme Clifford says Mr Martin is a regular swimmer at Cottesloe.

"He was due to meet his family a short time after; he didn't return," he said.

The beach has been closed until further notice.

EDIT; I have spent the last week or so trying to convince couple people I know who are new to Australia that shark attacks are very, very rare and that they have nothing to worry about -told em they have more chance being killed from being hit in the head by a falling coconut... and they should stop being silly and go down the beach for a swim once in awhile... and now this happens, I feel for the blokes family.

Went for my morning coffee at Cott this morning. Plenty of cops around, several boats patrolling and two jetskis with that body-slide thing on the back. Beach still closed.

Probably too early for the silly joke I want to make.

Condolences to the family. Now brace yourselves for the next round of anti-shark ignorance and worthless statistics.

I've been busting my arse trying to get access to the online tracking data for the CSIRO shark tagging project(s). Think google-earth with sharks. Not working though...all I'm coming up with is seal tracking.

I am very interested now to know what is actually going on with the Whites in Australia. It is starting to look like their behavior is changing and they are hanging around inshore waters more but I just don't know anywhere near enough to have an 'informed' opinion. Spent all night reading old journals on White Sharks instead of finishing off my essay on lobsters

Two fatal attacks in a month and a very high amount of sightings along the coast. I know it's shark season, but this seams like a bit of an anomaly...to my uninformed eyes anyway.

Also seems to be more reports of whale cacaces

More whale fatalities would definitely give whites a reason to come in shore and stick around. The past decade of 'archival-tag' data from whites along the south coast of Australia basically suggests that sharks will stick around shallow areas for unusually long periods of time if the feeding is good and then make a very sudden and very straight exit out to the 'shark highways' once the feeding dies off.

I've got absolutely no knowledge on whales and if there numbers are up. My Dad works with Doug at DEC (the number 1 man when it comes to whales). I might get him to ask him about it because I've heard rumblings and anecdotes about greater whale numbers but never seen any figures to back it up.

so sad for the family

it would be great if there would be someway of tagging these gws's to see where they go and do some more research on them. the more sharks that could be tagged then it could alert the local life guards any where on the coast to the fact there was a big shark in the area.

There is a way...and it's been done for over a decade and is still being done.
Go to Sandtrax/Port beach and you'll probably be able to spot the acoustic antennas used for picking up signals from acoustically tracked sharks (and other marine life, like seals).

A 5hitload of effort has been put in to track many different species of sharks and there is still a long way to go. Archival-tags were used and were shown to be pretty inaccurate as they relied on light-level data to be compared with astronomical data to determine the longitude of the shark. Then they started using acoustic tags which only worked in areas where you had a receiver and they only lasted for so long. It's only in the last few years that we've really been able to use long lasting GPS tags that not only record a whole range of data, but they last long enough and only weigh about 250g and are attached the dorsal fin and triggered using a sea level switch.

Unfortunately it's not a simple matter of just building a tag and bolting it onto the animals dorsal fin. It's taken a long time to develop a tag that collected the range of data required, lasted long enough and did not have any behavioral effects on the shark. You gotta remember, bolting something onto a fin can affect it's swimming behaviour and even more so, an electrical device can play on the sharks crucial hunting senses.

Also, as of 2003 there was almost 500 white sharks tagged in Australia...I don't know the current figures but I know a lot of work has been done.

Tragic news.
My brother who lives in Dunsborough and is a keen fisherman said to me this year he has sighted more whales along the SW coast than ever so definitely a possible reason for increased shark activity. Saying that though he reckons the great white population has been increasing each year for years. Peak season is rightly so around the whale migration (Aug-Nov) and salmon (Mar-Apr?) seasons. He and his mates have had close encounters diving sometimes only 50m off shore and now rarely go in the water during the peak seasons. Some young kids about to go skurfing the other week spotted a 5m about 25m off the boat ramp at Old Dunsborough! Apparently also some research group tagged around 100 or so sharks and when they came back to look for them found heaps but none were the tagged ones....thats scary!

It was my understanding that the Whale's are a little closer inshore this year..

I still will put it down to a reduction of smaller fish in the ocean means the sharks could be hungrier when they first get hear. So were once they would have sat back waiting they are searching for more food and earlier.
The biggest thing is for man to realise the effect we are having on a fragile ecosystem and we can't just keep treating our oceans like a food bowl, waste ground to dump rubbish and pollutants and then complain when our enjoyment is being effected.

My condolences to family and friends.

If there had off been a decent swell today and the waves were pumping --considering the great weather we have and all -sunny day, no wind etc etc..... I wonder how many people would risk it and be out in the water south of Cottesloe today?

I put it down to a dominant species getting protected when there were no actual accurate numbers of population at the time of the decision. (IMO)

Now: More numbers = More sightings = More attacks

Doug isnt in the office and my Dad doesn't specialize in whales at all, but he is under the opinion that whale numbers are on a steady increase over the last decade.

Hopefully can get more info later...in a lecture right now

Pretty scary, I was at cables for about 4 hours on that Sunday.

Suba, I've always respected your opinion on the marine wildlife, and you posted some things last time about the Bunker Bay attack that has questioned my opinions regarding sharks and surfers.

I don't mean to hijack the thread, and I know I'll get many people who disagree, but I have told my family if I get taken I would love the shark destroyed. In my humble opinion we are way too protective of sharks, we destroy dangerous dogs and bulldoze land for houses but protect the sharks. They're just a fish with teeth, we don't cry whenever average Joe reels in a herring (or when commercial fisherman take all the fish and make the sharks hungry).

But I bear in mind that my opinion could change because suba had brought up some good points last time there was a shark attack, and I think he did the time before that too (Gracetown).

You guys should check out a website called stopsharkcagediving.com
Everyone knows how far sharks travel so I wonder if there is any link with what's happening on the other side and what's going on in West Oz
Probably not but whatever it is it's a worrying trend

We destroy dangerous dogs because they are land animals. They are also non-native pests that actually do not have any natural 'right' (for lack of a better term) to even exist here. Sharks on the other hand are native and actually play an active and very vital role in our ecosystem. To me, that is a huge separation between dangerous dogs and dangerous sharks.

As for comparing sharks to normal bony fish. I do get what you're saying. I actually don't have a problem if someone catches a shark, kills it and eats it's meat...so long as it is sustainable and not wasteful. Herring are plentiful and at our current catch rates, are very likely to stay plentiful. On the other hand, catching some types of Tuna commercially is something I am against...same goes for the (suspected) over catching of the western rocklobster. It's just a lobster, yet the fishery is in an unhealthy state. Killing sharks is always going to be a problem. They breed slowly, are predated on by humans all over the world (have to remember that great whites migrate to non-protected waters) and play a vital role in keeping the marine system balanced.

I'm not against killing sharks because I think sharks are special. I'm against killing sharks because they are vulnerable. I have the same feeling for all other vulnerable species; sharks just happen to be where I am specialising

I have a theory. The vast majority of shark attacks in Perth have occurred in a marine area that forms a triangular shape between Rockingham, Garden Island, Rottnest Island and Cottesloe. If you have a look at Google Earth you can see a vast reef network that covers this entire area. It appears that this area is a white pointer feeding ground as all of the recent attacks at Cottesloe, Rockingham and Garden Island have occurred within this reef network area.

The moral of the story is that you are dramatically increasing your chances of being attacked if you enter the ocean within or near these areas. In saying that it could happen anywhere but it just seems odd that we've had 6 attacks in the same exact geographic location since 1997.

Food for thought.
