Octopus species uses taste sensors on sucker cups to detect harmful chemicals

A team of molecular and cellular chemists and biologists from Harvard University and the University of California, San Diego, has found that at least one type of octopus has taste sensors on its sucker cups that allow it to detect harmful chemicals. In their study, published in the journal Cell, the group tested the sensing ability of California two-spot octopuses.
