Migaloo the whale is turning 30, and the obsession with this albino humpback is far from on the wane

Migaloo the whale is turning 30, and the obsession with this albino humpback is far from on the wane With whale season upon us, all eyes are on the east coast of Australia in the hope of spotting Migaloo the albino humpback on his 30th birthday. Each year, the whale's obsessive fans try to capture the rare albino humpback through the lens of their cameras. He is just one of an estimated 35,000-plus humpback whales that migrate along the east coast of Australia each year from the cold waters of the Antarctic to the warm tropical waters of the Great Barrier Reef, and back again. But the obsession with Migaloo the white whale is far from on the wane.

For the first time at the world heritage-listed area, whale sharks — the world's biggest fish — have been captured on film attempting to mate.

Ningaloo Aviation pilot Tiffany Klein took rare photos of the tryst while she was aerial spotting, searching for the graceful giants of the sea, as part of her regular work for tour operators and researchers, such as the CSIRO who were out on the reef with her this week.

The liaison between two whale sharks is one of the few times mating has ever been seen .

This is the first time this behavior has been seen , let alone photographed, in the world. CSIRO research scientist Dr. Richard Pillans saw the whole interaction go down and said

"It's the first time I've ever seen it and the first it's ever been seen at Ningaloo," she said.

"I always take my camera with me because so many amazing things happen out there everyday and you don't want to miss those things.

"That was probably one of the most incredible things I've ever seen up here."

The tryst involved a 9-metre-long male whale shark, which had earlier been swimming with tour operators and their guests.

"He had been acting quite erratically, zigzagging around and up and down quite quickly," Ms Klein said.

"After they left, I was directing the CSIRO boat to go and have a look at it and the shark approached another smaller female shark and just swam straight underneath the female shark and, yeah, got a little bit frisky."

Despite this, scientists have never actually seen two whale sharks mating . While flying over Australia's Ningaloo Reef in mid-June, commercial tour pilot Tiffany Klein spotted an adult male whale shark trying to catch a juvenile female's attention by zigzagging through the sea for more than an

Unfortunately the feelings were not reciprocated.

"Yep, he was rejected, swam off away from them quite quickly," Ms Klein said.

'He was completely upside down'

CSIRO research scientist Richard Pillen was watching the whale sharks from a nearby boat when the waters became choppy.

"It's actually the first time we've seen it anywhere in the world," Dr Pillen said.

"It was an extraordinary experience to see this male shark, that was behaving really erratically for an hour before that while industry was swimming with him.

"He was turning and twisting and diving and swimming a lot faster than normal.

"And then we saw him catch up to a female shark, well we presume it was a female shark but no-one was in the water at the time, and then there was this huge big swirling and the male basically turned upside down.

"As you can see from the aerial images he was completely upside down, his clasp or his male reproductive organs are flared and he's attempting to mate with this female.

'World-first' inflatable surf reef to be installed at beach in Western Australia

'World-first' inflatable surf reef to be installed at beach in Western Australia What is believed to be the world's first inflatable surf reef is set to be installed at a beach in Western Australia. The new device, dubbed an Airwave, is a 2-metre high, dome-shaped bladder that builds on the natural swell of the ocean and uses air to create bigger surf waves. Inventor Troy Bottegal said the artificial reef was designed to work across all types of swell. require(["inlineoutstreamAd", "c.

"Unfortunately for him the female wasn't mature, she was too small to be a mature female, so his attempts were brushed aside but nevertheless the fact that that behaviour is taking place is extremely important."

Mating attempt may spark further research

The spectacle could even have big implications for future research of the whale sharks at Ningaloo.

"It's an incredibly rare event to see," Dr Pillen said.

"The fact that the males are actively trying to engage in mating behaviour suggests that Ningaloo may be an area where mating occurs is very exciting and certainly something that warrants further research."

Dr Pillen has been conducting research on the DNA of whale sharks to find out more about the behaviour and populations of whale sharks that visit the Ningaloo Reef each year.

The five-year project is a collaboration between BHP and CSIRO and involves attaching satellite tags to whale sharks to track where they go, as well as collecting DNA samples to help better estimate how many of the creatures visit Ningaloo and the Indian Ocean more broadly.

The research suggests the whale sharks can swim long distances.

"The animals at Ningaloo are basically genetically identical to animals on the opposite side of the Indian Ocean," Dr Pillen said.

"Animals in Madagascar and Mozambique have the same genetic make-up, which implies that there are animals moving a long, long distance, much further than the ones that we've tagged and that others have tagged here at Ningaloo."

The sighting also raised further questions, including where the female whale sharks go.

"The Ningaloo population is dominated by juvenile males and we see very few adult animals," Dr Pillen said.

"One of the questions is: where are the big females?

"We don't know where birthing happens and we don't know where mating happens."

Migaloo the rare white whale is spotted off the coast of Australia for the first time this year - as the iconic mammal turns 30.
The 40-tonne, 15-metre humpback albino whale typically turns up in New Zealand in late June before heading to Cape Byron or the Gold Coast in late July. But it appears the gigantic mammal may have started his annual migration a few weeks early, after a photo believed to be Migaloo appeared on Twitter on June 21.
