Octopuses Can Disappear Right Before Your Eyes: Here’s The Incredible Science Behind Their Powers
The octopus rarely stays the same shape or color for long. In the wild, its ability to disappear against a shimmering coral or jagged rockface continues to baffle even the most experienced marine researchers. These creatures transform their appearance not only in an instant, but with a precision that seems logic-defying.

Octopuses use mirrors to find food they cannot see
Octopuses may be even smarter than we thought. Researchers at Dartmouth found that octopuses can learn to use mirrors to locate food hidden behind them—a skill previously seen only in vertebrates like mammals and birds. After training, the animals correctly identified the food’s location about 73% of the time, showing they could use a mirror as a tool rather than simply reacting to a reflection.

Giant octopuses may have ruled the oceans 100 million years ago
Giant, fearsome octopuses may have once ruled the ancient seas, according to new research that flips the script on their evolutionary past. By uncovering exquisitely preserved fossil jaws hidden inside rock, scientists revealed that early octopuses from the age of dinosaurs weren’t shy, soft-bodied drifters—they were massive apex predators, possibly stretching up to 20 meters long and crushing prey with powerful bites.
This Week in Science: Giant Octopuses, a Promising Cancer Vaccine, And More!
Our weekly science news roundup.
Earliest octopuses were Kraken-like sea monsters, fossils show
Whale-sized, monstrous octopuses prowled the seas during the Age of Dinosaurs, snatching prey with their huge tentacles and crunching them with powerful jaws, fossils from B.C. and Japan suggest.
Meet the 19 metre octopus that may have prowled ancient seas
Giant octopuses may have ruled the oceans 100 million years ago, according to fossil evidence.
Giant, 60-foot octopuses were apex predators 100 million years ago, fossil discovery shows
Rare fossil finds show colossal octopuses were among the top ocean predators during the Cretaceous Period, according to a new study.

Scientists discover the world's oldest 'octopus' fossil is a different 300-million-year-old critter
The ‘oldest octopus’ in the world isn’t an octopus after all, scientists find
The story of a 300-million-year-old fossil has been rewritten after scientists discovered that it doesn’t actually belong to the world’s oldest octopus as previously thought.
The ‘oldest fossil octopus’ is probably another animal
In 2000, researchers thought they found the oldest fossil octopus, which lived over 300 million years ago. But it may just be a half-rotten nautilus.
The world’s “oldest octopus” was never an octopus
A famous “oldest octopus” fossil has been exposed as a case of mistaken identity. Advanced imaging revealed hidden teeth showing it was actually related to a nautilus, not an octopus. The confusion came from decay that altered its shape before fossilization. This discovery rewrites part of evolutionary history, pushing the true origin of octopuses much later in time.

Stanford scientists create shape-shifting material that changes color and texture like an octopus
A new shape-shifting material can change both its texture and color in seconds, inspired by the camouflage abilities of octopuses. By precisely controlling how a polymer swells with water, researchers can create detailed, reversible patterns at the nanoscale. The material can even mimic realistic surfaces and dynamically adjust how it reflects light. In the future, AI could allow it to automatically blend into its surroundings.

But behind the scenes, things get even stranger. Nearly all cephalopod females mate with multiple males and can store sperm for weeks to months. That means each female carries a tiny archive of potential fathers. So the big question becomes: when everyone is competing for a spot in that archive, how do cephalopod females decide who to mate with, and can they control whose sperm ultimately fertilizes their eggs? About the Speaker Theodora is a PhD student in Marine Biology at Scripps Institution of Oceanography, UC San Diego. Prior to starting at SIO, Theodora researched chronic reproductive pain conditions in New York, created marine science multimedia as a science communication intern at Point Reyes National Seashore, and studied cephalopod neuroethology as a research intern at Okinawa Institute of Science and Technology. Theodora currently studies the evolutionary and behavioral dynamics of female choice in cephalopods, with a focus on local California market squid.
