Octopuses Like to Punch Fish, New Research Suggests
Upsetting but strangely satisfying new research documents octopuses punching fish during collaborative feeding sessions. The octopuses primarily do it for practical reasons, but sometimes these underwater jabs seem to be purely spiteful. We learned so many disturbing things this year, and we regretfully have to add another item to the list: Octopuses like to punch fish.

Do Octopuses Have Dreams? They Might, and Undergo Frenzied Shifts in Color
Scientists in Brazil said an octopus' wild shifts in color, behavior, and movement serve as evidence of a sleep cycle - suggesting the octopus pivots between active and quiet sleep, just like humans shifting between deep and REM sleep, according to a new study published in the journal iScience .

Scientists: Octopuses Love to Fling Objects at Each Other
Six years ago, a team of scientists from the University of Sydney filmed common Sydney octopuses ( Octopus tetricus) "throwing" shells, silt, and other seafloor detritus at each other. At the time, it wasn't clear whether they were actually targeting one another or if the other octopuses were merely collateral damage, since they use the same "throwing" mechanism to discard food or build dens.

Octopus and human brains share the same "jumping genes"
Researchers at International School for Advanced Studies (ISSA) in Italy may have just discovered the reason for the remarkable intelligence in octopuses and active jumping genes. Interestingly, the jumping genes found active in octopuses are also active in the human brain, according to a press release by the instutition.
