Beachgoers have been left surprised by dolphins as they swim close to the shore.

In a video shared by the Institute for the Conservation of Nature and Forests (ICNF) on social media, you can see several dolphins swimming next to a beach in Tróia.


On Facebook, in addition to revealing that the video was captured in Tróia, the ICNF highlights that this was an "involuntary observation" by Roazes-do-Sado.
