Robotic drones with suction pads can fly, swim or hitch a journey

A robotic drone that may journey via air and water, and in addition connect itself to bigger objects with a suction cup, might be helpful for tagging wild animals, say its creators. The suction cup is impressed by the remora fish, which attaches itself to bigger marine creatures in a symbiotic relationship the place the remora eats parasites that will irritate its host and in addition will get a journey in return.
