This is the moment maritime officials in Argentina find themselves accompanied by a group of playful dolphins as they patrol the Beagle Channel, named after HMS Beagle, which carried Charles Darwin on his famous voyage. The tiny orange vessel which the dolphins were filmed swimming around was part of the Argentine Naval Prefecture (Prefectura Naval Argentina) or PNA, which is part of the Argentine Security Ministry. It has the job of protecting both the country's rivers and its maritime territory. The group of dolphins was seen in the Ushuaia area, in the Tierra del Fuego province of southern Argentina, when the boat was one of several on a patrol organised by the PNA.
