Think those guys make their own right of way.

this is what the shark research institute say...

The presence of porpoises and dolphins may indicate sharks are hunting in the area.
Reason: These species often feed with sharks. Dolphins and sharks are both fish eaters.

Leave the water when pods of dolphin cluster or head inshore
Reason: This behavior is often associated with the proximity of sharks.

I duunnoooooo I heard the opposite: that dolphins ram sharks with their bony snout and can really hurt a shark with a good shot in the flank.... so about the only animal in the ocean that a shark will flee from is a dolphin. I'm sure that was a doco on TV years ago

who is right?

that's kinda where me email came from, i showed a mate at work and he said same thing. i also thought that but a year ago i saw a doco on sharks and it changed my view because they filmed sharks and dolphins hunting together.

doesn't bother me really, i don't go in the water anymore, just post on seabreeze cause it's safer.

I am a marine biologist and I can say that that is a load of crap. No offence to the person who posted it.

no offence taken,


i'm not a marine biologist can only go on what i have read etc.

have you got any data to prove it's wrong?

i would love to know once and for all cause there seems lots of different outcomes on this one.

cheers.

Perhaps, while there's plenty of food, dolphins and sharks get on with their own business without worrying each other.
But if food is scarce, and there are young vulnerable dolphins around, and a biggish shark turns up, then the dolphins are either going to run or fight, and it may not be predetermined which way they go.

dralyagmas, can you enlighten us?

Weeeeeeeell,

I have been surfing at one of our local spots a few years back and we had a pod of dolphins round up a school of salmon up against a groyn.

We all thought it was cool watching the dolphins riping around and under us ctaching the salmon, until we turned around to see a dirty great big noah go cruising past about 15m away. The break got cleaned out rather quickly.

After we got changed we sat on top of the rock wall watching both the sharks and dolphins hook into the fish, it was a good show.

Was it your groyn Elmz?

One of our locals groynes, I fordets whos it twas

The Ichthyology Department of the Florida Musuem of Natural History's International Shark Attack File states that the prsence of dolphins does not exclude the possibly of the presence of sharks as they eat the same things.

However from my own perspective I have seen 1000's of dolphins and never seen a shark, and that is while surfing, windsurfing and sailing (not really looking) and diving and snorkling (looking).

It would depend on what the dolphins are doing. In the photo that Windy posted the dolphins are playing in the waves and not fishing so the likelihood of a shark bieng close would be the same (IMHO) as if the dolphins were not there. If, like elmo said, the dolphins are rounding up fish then there could be sharks. But the risk is the same as if the fish were there without the dolphins.

My opinion is that the presence of dolphins has no bearing whatsoever on the probability of sharks being present.

Personally I would not go surfing when there are schools of salmon in the water, whether there are dolphins there or not.

Just dont bring the sharks back here Kev

Hey Greenie
We are currently in negotiations with CSIRO who did all that tracking work with 5 MASSIVE Great Whites a year or so ago (They tracked them using satellites traveling across the bite off towards South Africa and Tassie and back)

Looking to get a couple of Whities to head up north WA around October where they will be sticking relatively close to the coast... there's a little place up there a little way off the beaten track that's perfect for this type of operation !

Can you train them to hunt down kiters?
