This gif is a clip from a National Geographic video filmed at an aquarium.
The staff kept finding dead spiny dogfish sharks on the floor of the tank and decided to investigate. The culprit turned out to a be an octopus. The aquarium assumed that the octopus would use it’s color changing camouflage as a defense mechanism to avoid the sharks, but it instead wiped out its enemies in return for a safe environment.
Michael Smith was studying honeybees at Cornell when one flew up his shorts and stung him in a delicate place, as National Geographic reports. Yet unlike most people, who would have screamed and sworn and maybe put on pants, Smith used the unexpected sting as inspiration to study where a bee could do the most damage in terms of sheer pain.
National Geographic magazine put together this gif showing how their maps have expressed the extent of the sea ice in the Arctic Ocean over time - even the maps are showing the rapid retreat of summer sea ice.
