The SA government has convened an emergency meeting today to discuss taking cuttlefish eggs from the wild, due to the impending threat of the algal bloom which could wipe them out forever.
Animal welfare laws don’t protect invertebrates, but there’s evidence that some, such as octopuses, are as intelligent as many mammals – even if their cognition takes very different forms.
With nine brains, blue blood and a talent for camouflage, the octopus is one of the most fascinating creatures in the sea.
The fossil is the oldest known vampyropod to date.
Octopus, crabs, prawns demonstrate clear signs of emotion, such as pain and ‘anxiety-like’ behaviour.
They can open jars, use tools, remember instructions and attack on command. But they’re still not the smartest cephalopod in the sea…
In the red corner is the octopus with eight muscular, hyper-flexible arms. In the blue corner is the bird with killer vision and two sharp claws for catching prey with incredible speed and precision.
Colour-changing patterns in snoozing octopuses are characteristic of two alternating sleep states.
If octopuses simply started evolving a smarter brain, what stops them from ruling over humans? Why has this not happened already? An expert explains what these cephalopods might be capable of.
A marine version of the Stanford marshmallow experiment helped show cuttlefish can delay gratification.
Some scientists say attributing ‘human-like’ qualities to animals is misleading. Others say it’s a great tool for conservation. Either way, the Netflix hit My Octopus Teacher has a positive message.
We recorded the largest number of bigfin squids ever seen in one area. Before this, this rather elongated creature had only been spotted a dozen times across the globe.
New squid research north of New Zealand nearly doubles the known cephalopod diversity in the Kermadec region, where a proposal to create one of the world’s largest marine reserves has stalled.
In May-August each year, giant Australian cuttlefish gather and mate over a narrow stretch of rocky coastline in South Australia. At their peak you see literally one cuttlefish per square metre.
Elusive and mysterious by nature, ordinary people are revealing the secrets of the UK’s octopuses.
Over 20 cephalopods crawled on to New Quay beach. What was going on?
A new study shows cephalopods edit messages from their DNA, allowing them to adapt faster to their environment.
Cephalopods are able to adapt rapidly to changing conditions.
The myth of a monstrous giant squid prowling the oceans has persisted for centuries but scientists have been able to reveal the truth behind the stories.
