Octopuses follow two strategies to squeeze through tiny holes
Researchers have documented two separate movement strategies octopuses employ when navigating openings smaller than their bodies. For moderately tight spaces, the animals lead with their arms and pull the rest of their body through. When gaps become extremely narrow, they reorganize all eight arms and their soft mantle into a coordinated sequence that changes shape progressively, allowing them to pass through holes a fraction of their body width. The findings come from controlled experiments and high-speed video analysis.

- ✓ Octopuses employ an arm-first strategy for moderately small openings.
- ✓ For extremely tight holes, octopuses reorganize arms and mantle into a progressive shape-changing sequence.
- ✓ The research was conducted using controlled experiments and high-speed video analysis.
- ✓ Findings may offer design principles for soft robots operating in confined spaces.
What changed
A new study identifies and characterizes two distinct, context-dependent squeezing strategies rather than treating the behavior as a single continuum.

Octopuses use two distinct strategies to squeeze through tiny holes
Researchers have documented two separate movement strategies octopuses employ when navigating openings smaller than their bodies. For moderately tight spaces, the animals lead with their arms and pull the rest of their body through. When gaps become extremely narrow, they reorganize all eight arms and their soft mantle into a coordinated sequence that changes shape progressively, allowing them to pass through holes a fraction of their body width. The findings come from controlled experiments and high-speed video analysis.
Why it matters
Octopuses are known for extreme flexibility, but the mechanics of how they fit through openings far smaller than their beak, the only hard part, have been poorly quantified. Understanding these distinct motor programs could inform soft robotics designed for search-and-rescue or medical procedures in confined spaces.
What is confirmed
- Octopuses employ an arm-first strategy for moderately small openings.
- For extremely tight holes, octopuses reorganize arms and mantle into a progressive shape-changing sequence.
- The research was conducted using controlled experiments and high-speed video analysis.
- Findings may offer design principles for soft robots operating in confined spaces.
What to watch next
- Publication of the full peer-reviewed paper with kinematic data
- Replication of the two-strategy framework in other cephalopod species
- Application of the movement patterns in soft-robot prototypes
