Animal Behavior
A new analysis of fossil bones suggests that Australia's extinct giant kangaroos, once thought too bulky to hop, may have bounced after all. Researchers found adaptations in their leg structures that could withstand the stresses of hopping. These findings challenge long-held assumptions about the locomotion of these massive marsupials.

A re-examination of a 1970s fossil has revealed that Hallucigenia, one of the oddest creatures from the Cambrian period, may have fed on the corpse of a comb jelly. The discovery shows spines from seven Hallucigenia individuals scattered over the remains of the gelatinous organism. This provides a rare glimpse into the ancient animal's possible diet and behavior.
Researchers have discovered that octopuses can use their suckers to sense harmful microbes on surfaces such as crab shells or their own eggs. This finding was highlighted in a science discussion on September 12, 2025, revealing new insights into cephalopod sensory capabilities. The ability allows octopuses to avoid contaminated food or protect their offspring effectively.
