Videos capture orcas’ tricks for taking down the largest fish on Earth
Citizen science videos document for the first time how orcas coordinate an attack against whale sharks.

For deep-diving whales, plastic garbage may ‘sound’ like food
Experiments show that the acoustic signature of plastic and prey is similar. That may confuse whales that use echolocation to hunt.

Why a small seabird dares to fly toward cyclones
Tracking data show that Desertas petrels often veer toward cyclones and follow in their wake, perhaps to catch prey drawn to the surface.

Octopuses and squid are masters of RNA editing while leaving DNA intact
Modifications to RNA could explain the intelligence and flexibility of shell-less cephalopods.

RNA editing helps octopuses cope with the cold
California two-spot octopuses tweak the proteins they make, potentially to help maintain brain function when temperatures dip.
- Animals
Octopus, squid and cuttlefish arms evolved to ‘taste’ different compounds
Octopus suckers can taste a variety of greasy, sticky molecules, while squid and cuttlefish suckers detect bitter compounds.

Remote seamounts in the southeast Pacific may be home to 20 new species
A recent expedition to the intersection of two undersea mountain chains has revealed a new seamount and a rich world of deep-sea biodiversity.
- Life
Squid edit their RNA to keep cellular supply lines moving in the cold
Squid change their RNA more often in the cold, producing motor proteins that keep cellular cargo on track.

Invisible comet tails of mucus slow sinking flakes of ‘marine snow’
New measurements reveal the gunk that surrounds the particles, an important factor in understanding how the ocean sequesters carbon.
- Animals
Scientists have now recorded brain waves from freely moving octopuses
The data reveal some unexpected patterns, though it’s too early to know how octopus brains control the animals’ behavior, a new study finds.

The animal kingdom never ceases to amaze
Editor in chief Nancy Shute revels in the wonder of animals, from psychedelic toads to extinct pterosaurs.
