Whyalla is on the southern coast of Australia.

Every year, for a few months between May and August, Giant Cuttlefish arrive and congregate in a patch of shallow water just out of town. This is the only known gathering of large numbers of cuttlefish, and the results are a unique spectacle not replicated anywhere else.

It’s not known how far they migrate, or why they choose that particular area, but they have appeared reliably every year, in tens of thousands, along the same few miles of coast. 

They gather to reproduce-  those months are a continual melee of courting, fighting, mating, and the laying of eggs, all accompanied by an unending chorus of color changes.



How deep is the water?

The cuttlefish aggregate in 2-6 metres of water along a six kilometre stretch of the Point Lowly and Black Point. Perfect for snorkeling. This peninsula is 20 kms north of the city of Whyalla.

The aggregating sites are accessible from shore.

Giant Cuttlefish

Close encounters of the third kind 

Whyalla offers the opportunity to interact with a creature unlike other animals.

Diving with the giant cuttlefish can feel very otherworldly.

The strange facts that make the cuttlefish so different are:

-   ​Cuttlefish have three hearts

-   Their blood is green in colour

-   Studies have proven they are capable of counting

-   Cuttlefish can perceive light polarization, can see 360 degrees & have no blind spots

-   They can instantly change colour and shape to match their surroundings

-   Their lifespan is only 1 - 2 years & only one breeding cycle.

There are over 100 different species  of Cephalopods. Whyalla is home to 12 species:

     The southern dumpling squid

     Southern blue-ringed octopus

     Southern pygmy squid

     Southern keeled octopus

     Southern sand octopus

     Southern torpedo squid

     Common octopus

     Southern bobtail squid

     Koch's bobtail squid

     Southern calamari

     Pinstripe bottletail squid

     pajama squid

The Giant Cuttlefish is the largest cuttlefish species.  They can grow to over 3 feet in length & weighing up to 10kg.
