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.

Research Overview

In a recent study, scientists found that octopus suckers function not only for grasping but also for chemical sensing. By detecting microbial signatures, octopuses can identify potential threats like bacteria on objects they encounter.

This sensory mechanism is particularly useful for egg-laying females, who can assess the cleanliness of surfaces before attaching eggs. The discovery adds to our understanding of how marine animals interact with their environment at a microscopic level.

Broader Context

The research was discussed alongside other topics in a popular science program, emphasizing advancements in marine biology. Further studies may explore similar abilities in other cephalopods.
