A whale has appeared in a port at one of Buenos Aires' most exclusive neighborhoods, periodically surfacing alongside luxury yachts while attracting hundreds of onlookers.

The whale surfaced Monday afternoon in Puerto Madero, an area of towering office buildings and high-end lofts. In the middle of the neighborhood is a body of water the size of a few square blocks where many residents keep their yachts.

News of the whale quickly spread on social media and the newscasts.

Authorities have not identified the type of whale, and it's unclear how they will get it back to sea. A port police boat is traversing the waterway, apparently trying to lure the animal to the connecting Rio de la Plata river, which feeds into the Atlantic Ocean.
