What unusual activity do the horses engage in that one might not typically see in a beach setting?

In the image, the unusual activity is that a group of horses is walking on the beach near the ocean. It is not a common sight to see a herd of animals, particularly horses, on a beach as they are typically found in rural areas, fields, or stable environments. Beach visitors usually expect to see people, sunbathers, and even birds or small marine animals, but not horses. This unique occurrence creates an interesting visual in the image as the horses roam by the water's edge, adding a different dimension to the typical beach scenery.
