Killer Whales Off Spain Develop Unique Language, Attack Boats

A group of killer whales, led by an individual known as White Gladis, has been involved in a series of aggressive encounters with boats off the coast of Spain. These incidents, which began in 2020, have resulted in damaged vessels and endangered sailors, prompting scientists to investigate the unusual behavior of this particular pod.

Researchers have identified that the orcas are not only attacking boats but are also communicating with one another in a distinct set of sounds that has never been documented before. The findings suggest that the pod has developed a unique language that includes a combination of four different vocalizations.

Dr. Renaud de Stephanis, the president of the Conservation, Information and Research on Cetaceans (CIRCE), has dedicated years to studying these animals. He remarked to The Times, “We’ve been studying these orcas for 30 years. Until now they were thought to be very silent. But now we’ve learnt that their calls are totally, totally different to any others.” This revelation is significant from a cultural conservation perspective, akin to discovering a new human language in Europe.

The orcas typically remain quiet while hunting to avoid alerting their prey. Yet, they are known for their vocalizations, which often include clicking and whistling sounds. Historically, scientists have classified various orca calls as accents rather than entirely new dialects, but White Gladis and her pod have demonstrated a level of complexity that sets them apart. Dr. de Stephanis likened their communication to the differences between Arabic and Latin, indicating a profound linguistic divergence.

The pod has reportedly been sighted over 700 times since the onset of their aggressive behavior, with at least 15 killer whales suspected of involvement in boat ramming incidents. Footage has surfaced showing at least three killer whales attacking a luxury sailboat near Fonte da Telha beach, causing the vessel to capsize. Fortunately, all five individuals aboard were rescued.

In a separate incident, a second boat was immobilized after being struck by the orcas, which resulted in a broken rudder. The crew was successfully evacuated back to shore. Just days later, another boat was targeted off the coast of Portugal, leading to a rescue operation for four individuals aboard a sailboat in Costa da Caparica. These incidents have raised concerns among local sailors and prompted calls for further research into the orcas’ behavior.

As scientists continue to study this remarkable pod, the development of their unique language may provide crucial insights into orca communication and behavior. The ongoing investigation highlights the need for a better understanding of these complex creatures and their interactions with human activities in their habitat.
