The hectocotylus is both a reproductive and sensory organ, Harvard scientists and others have found. Octopuses are some of ...

How do octopuses mate in the dark? A new study shows how the hectocotylus arm uses progesterone receptors to "taste" for a mate.

Scientists found that the male’s hectocotylus, the specialized arm for mating, is lined with receptors that can sense ...

A new study by Harvard biologists reveals how octopuses feel their way to potential mates with a "taste by touch" sensory ...

A new study led by Harvard biologists, in collaboration with the University of California San Diego, the Okinawa Institute of ...

It has been confirmed that octopuses can mate if their arms are within reach, even without seeing each other. This is because ...

"In octopus, we found that these chemotactile receptors physically contact surfaces to determine whether the animal should eat a potential food source or reject it," said Hibbs. "Through its structure ...

When the scientists paired two male octopuses in the same setup, the males interacted by touching arms, but they never ...

People have different tastes. It turns out that octopuses, squid and cuttlefish do too. These soft-bodied cephalopods have proteins on suckers along their tentacles that allow them to “taste” by ...

"But the binding pocket of the octopus receptor, although in a similar spot that the ancestral neurotransmitter sticks to, is very different," Bellono said of the large, sticky surface. "And we ...

A new study by Harvard biologists reveals how octopuses feel their way to potential mates with a “taste by touch” sensory system and even can couple at arm’s length without actually seeing each other.
