The protein actin is crucial for one of the last steps in cell division – a process called cytokinesis. At the end of cell division, the two resulting cells separate. Actin filaments form a ring in ...

For the first time, marine biologists have measured the energy demands of octopus color changes, revealing that the process ...

Now, biologists have measured how much energy octopuses use during their complete color transformations, providing new insights into their biology. While the advantages of an octopus's color ...

For the first time ever, marine biologists have measured how much energy octopuses really need to change color — and it's a ...

Energy trade-offs of octopus camouflage. While the benefits of an octopus' color-changing abilities are well-documented, the ...
