Let's flap our flippers and delve into knowing a bit more about penguins. How many kinds of penguins can you name? Today's snapshot features agile macaroni penguins swimming in the plankton-rich waters of the Drake Passage in Chile. These charming creatures are just one of 18 species of penguins found in the Southern Hemisphere and can be recognised by their peculiar amber crests and prominent orange beak. Macaroni penguins gather in foraging groups, but males can be aggressive towards each other. To show passivity and avoid a fight, individuals often ease through colonies with their heads tucked down to their chests. Despite being beloved by us humans, penguins are threatened by reduced food availability, errant fishing nets and the profound impact of climate change on their habitat, sea ice.
