Proyecto ORCA estimates that there are 14 individuals breaking rudders of sailboats in the Strait.

ORCA Project Cádiz, an association whose main purpose is to disseminate and raise awareness about the situation of orcas in the Iberian Peninsula, particularly in the Strait, has counted that there are 14 individuals, all females, which in the vicinity of Campo de Gibraltar, break or deform the rudders of sailboats, leaving them without control and needing to be towed to a port for subsequent repairs.

"If this were a defensive response, such behavior would be perpetrated by adults protecting themselves and their offspring from a possible threat. However, this is not the case, as there are only 2 adult females involved, and the other 12 are actively participating juveniles," state the members of this association, which has created a catalog to effectively monitor the population.
