An Australian Giant Cuttlefish putting on a wonderful display at Cabbage Tree Bay Aquatic Reserve this morning. He changed his colour from mottled brown to deep red in the first clip in about 1/3 sec, from counting the number of frames from start to finish of the colour change

We couldn't help but share one of our most charismatic #research species this #MolluscMonday. This beautiful eye belongs to a cuttlefish, with their distinctly shaped pupils enabling them to see almost completely behind themselves, with no blind spot! 🐙 🐚 🦑

Happy Halloween! Because of their proficiency in camouflage, everyday is Halloween for cuttlefish. This reaper cuttlefish is going as a demon 🦑

Cuttlefish, despite being colorblind, can still change the color and texture of their skin in order to camouflage to their surroundings.

What is your favorite color?

Despite its name, the flamboyant cuttlefish isn't very buoyant. Due to its shrunken cuttlebone, this species "walks" along the seafloor rather than swimming.

Cuttlefish are extremely intelligent. Out of all 1.25 million species of invertebrates, they have the largest brain to body ratio! Studies have proven that some cuttlefish are capable of problem-solving, observational learning, and spatial learning.

Cuttlefish are also wonderful dancers! This one is using flashing light in order to hypnotize its prey.

Cuttlefish control their buoyancy with their cuttlebone, an internal shell. The cuttlefish controls the levels of gas/water in the chambers of the cuttlebone in order to rise/fall in the water.
