Octopuses Use Microbial Signals to Guide Complex Behaviors A new study published in Cell from the lab of MCB faculty member Nick Bellono reveals that octopuses detect microbial cues on surfaces to distinguish prey and eggs from inanimate objects—an astonishing example of how animals can sense their environment through the invisible world of microbiomes
A taste for microbes — Harvard Gazette The octopus senses the chemicals made by certain microbes, such as those growing on the surfaces of crabs or eggs, to distinguish the vitals of these surfaces ”
‘Truly amazing’: Octopuses ‘taste’ harmful microbes with . . . Nicholas Bellono, a molecular biologist at Harvard University, suspected octopuses might also be reacting to microbes they encounter He and his postdoc Rebecka Sepela observed mother California two-spot octopuses (Octopus bimaculoides) in the lab sorting through their eggs and tossing some out
Microbe Flavors Tell Octopuses Which Babies Deserve Their . . . Octopuses can taste with their arms, and a new study reveals that specifically, they're tasting chemical cues from microbes that grow on the surface of objects like dead crabs and living octopus eggs
Octopuses’ 8 Arms Snoop on the Microbial World - DNyuz Researchers reported on Tuesday in the journal Cell that octopus arms are fine-tuned to “eavesdrop into the microbial world,” detecting microbiomes on the surfaces around them and deriving information from them, said Rebecka Sepela, a molecular biologist at Harvard and an author of the new study
Environmental microbiomes drive chemotactile sensation in octopus Signals from environmental surfaces activate octopus chemotactile receptors, influencing behaviors such as maternal care and predation, thereby highlighting the role of microbiomes in shaping animal sensory systems and ecological interactions
