According to firefighters, the phenomenon is related to changes in oceanographic conditions typical of the season, such as the frequent passage of cold fronts, changes in winds, sea currents and undertows, among other factors that can transport animals closer to the coast. Still according to firefighters, another factor is the entry of colder waters from the South, in addition to the "natural dynamics of marine ecosystems". Although it raises concern, they are a natural and seasonal phenomenon according to firefighters. ?
