Baby sharks stick close to shore

Scientists have shown for the first time that juvenile great white sharks gather in nearshore waters up to 10 meters deep with temperatures between 16 and 22 °C – a very different habitat from that of adults. These preferences may optimize their growth and minimize the risk of predation. These results can inform conservation efforts and help avoid unwanted encounters with swimmers.

Tiny crustaceans discovered preying on live jellyfish during harsh Arctic night

Scientists used DNA metabarcoding to show for the first time that jellyfish are an important food for amphipods during the Arctic polar night in waters off Svalbard, at a time of year when other food resources are scarce. Amphipods were not only observed to feast on ‘jelly-falls’ of dead jellyfish, but also to prey on live jellyfish. These results corroborate an ongoing ‘paradigm shift’ which recognizes that jellyfish aren’t a trophic dead-end but an important food for many marine organisms.
