WA father, 51, feared taken by shark

The search for a man feared taken by a shark off a West Australian beach has so far failed to find him.
Brian Guest, 51, was snorkelling for crabs with his son off their local beach near Rockingham, south of Perth, when he suddenly disappeared from view shortly after 7am (WDT) on Saturday.
His 24-year-old son, identified by Perth Now as Daniel, swam to shore and raised the alarm.
Witnesses told police they saw flashes of fins in the area and the water was coloured by blood.
"Something very traumatic and pretty violent has happened there and we are treating it as a probable shark attack," acting Inspector Mark Valentine told AAP.
"There was lots of talk among witnesses at the incident location about seeing fins in the water but we can't yet say whether there was definitely a shark out there, though in all probability that's what it is."
The beach was immediately closed as police, marine rescue patrols and three helicopters mounted a huge search for the missing man.
The 10km beach is a popular swimming location and there were many people out because of the early morning warm weather conditions, Insp Valentine said.
Witness, local resident Luke Tubbs, said the son was in shock on the beach.
"He was on the beach shaking and looked really white and he was just really shocked," Mr Tubbs said.
The three emergency service aircraft, 10 boats and divers conducting a grid search by late Saturday afternoon had found nothing.
Family spokesman and police officer Steve Kent told reporters Mr Guest was a devoted husband and father who knew the dangers of swimming in the ocean.
"(He's) an avid fisherman, an avid diver and a loving husband and father," Sergeant Kent told reporters.
"His son and he were out in the water, which he had done quite regularly.
Unfortunately, this morning there was a shark in the water and it's taken the father.
"At the time his son didn't actually sight what had happened but there were some people on the beach that saw and heard some things in the water.
"His son ran from the beach to his nearby home and that's when they called police and went down to try to find the father in the ocean."
Sgt Kent said the 51-year-old, who worked in the banking industry, knew the ocean's dangers and had spent "many, many years diving and fishing and (has) a very deep respect for the water and he knows the dangers of being in the water".
Asked if the family wanted the shark hunted and killed, Mr Kent said: "No, no, definitely not."
"It's nature and we should pay respects to nature and nature's way.
"It is a shock loss to family and friends. He's a loving father and husband that appears to have been taken by a shark.
"We ask that people respect that there is a need for time for grieving and for time and for chances and hopefully, at least, that the husband will be recovered in the near future.
"They've got a lot of family and friends around them and wish and hope they be given the time.
"It's something you don't expect and don't wish to happen to anybody."
It's the second fatal shark attack this year.
In April, 16-year-old surfer Peter Edmonds died after being attacked by a shark at Ballina, on the NSW north coast.
Meanwhile, a kayaker was tipped into the water off Sydney's northern beaches while a white pointer circled on Saturday.
Nearby fishermen hauled the man into their boat and out of harm's way, and another two kayakers clung alongside as the five-metre shark continued to circle off Long Reef.
