Giant Australian Cuttlefish have returned to waters near Point Lowly en masse with numbers tipped to be more than 150,000.

Local diver Tony Bramley said there was a visible abundance of the species, Sepia Apama, estimating numbers this breeding season have more than doubled from 2014 figures which recorded around 60,000. ...

Giant cuttlefish numbers are soaring after nearly disappearing
The Advertiser Brad Crouch September 25, 2015


GIANT cuttlefish – the “rock stars” of SA’s marine environment – are rebounding in huge numbers near Whyalla, just a few years after the population had all but disappeared.

New figures show a dramatic increase in the world’s largest cuttlefish at rocky ledges off Port Lowly, where they gather to breed annually.

The population has increased by 128 per cent to more than 130,000 compared to 57,000 last year — also an increase on the previous year.

Fisheries Minister Leon Bignell said the giant Australian cuttlefish was an iconic South Australian species which drew visitors from all over the world. Tourists dive in the shallow waters and watch the cuttlefish light up spectacularly during mating rituals.

“Just a few years ago, the cuttlefish population all but disappeared for some reason,” Mr Bignell said.

“This year’s survey by the South Australian Research and Development Institute shows conditions have been very favourable over the last two spawning seasons.


“The Whyalla Cuttlefish Citizen Scientist Group has again been active this year, undertaking surveys throughout the season to complement SARDI’s formal monitoring program.

“It’s so good to see the willingness and enthusiasm of local divers to get involved in the research and it goes to show just how valued this remarkable species is.”

Conservation Council SA chief executive Craig Wilkins said the results were encouraging. “The Giant Australian Cuttlefish are the rock stars of South Australia’s marine environment,” he said.

“This year’s numbers provide a promising sign the population is recovering from the dramatic low seen in 2013.

“That’s tremendous news.”

Giant cuttlefish numbers bounce back in South Australian waters, numbers up 128 per cent this year

Breeding numbers of giant cuttlefish are bouncing back in South Australian waters, with a 128 per cent rise this season.

Fears had been held for the sepia apamaspecies population, when in 2013 numbers dropped to 13,500.

But two consecutive years of growth has seen the population rise back to an estimated 130,771 this year.

Dr Michael Steer has researched giant cuttlefish for the South Australian Research and Development Institute (SARDI) for more than a decade. ...

Whyalla close to the heart of Cuttlefish Country

This year Whyalla will be the first town in the state to hold a screening for the feature-length environmental documentary Cuttlefish Country produced by Daniel and Emma Monceaux.

The film documents the clash between industry and environment as the industrialisation around Point Lowly threatens the habitat of the Giant Australian Cuttlefish who migrate there every year for breeding purposes. ...

Weekend cuttlefish dive sold out
June 29, 2016
A Giant Cuttlefish dive to be held in Stony Point this week has sold out as residents gather to catch a glimpse of Whyalla’s signature sea creature.

The dive will take place over four days from Thursday through to Sunday, with good conditions expected for most of the event.

The event will be hosted by Experiencing Marine Sanctuaries, and Executive Officer Carl Church said this is the first time the dive has been held in Whyalla.

“We’ve received some good support from the community, we’ve been forced to close registrations because over 600 people have signed up,” he said.

“Those who still want to participate in the dive will have to bring their own diving gear because we have run out of supplies.”

Following a safety briefing participants will be heading into the water in groups of six with a certified instructor.

Why we're watching the giant Australian cuttlefish
August 15, 2018 by Bronwyn Gillanders, The Conversation




Australia is home to the world's only known site where cuttlefish gather to mate en masse.

From May to August, if you head into the water around Point Lowly, South Australia, it will be a chilly 12℃. But you'll be able to observe what look like aliens – hundreds, even thousands of tentacled organisms with their unusual distinctive W-shaped eye pupils, and pulsating colours moving across their body.

Intent on mating, the cuttlefish will be totally oblivious to your presence.

But this population of cuttlefish dropped in abundance from an estimated 150,000 animals in the late 1990s to only 13,492 in 2013.

Although counts in recent years suggest the creatures have recovered, my research aims to determine what sorts of factors influence this very unique cuttlefish population. This may allow us to better manage and protect the species – important not just for science, but also for the local environment and economy.
