Unprecedented orca attacks in Gibraltar: Scientists probe the cause
In the region of the Strait of Gibraltar, a 15-metre yacht sank. Fortunately, none of the passengers were injured. This is yet another incident, so scientists are trying to find an explanation. A group of killer whales responsible for the attacks and swimming in the Mediterranean Sea consists of about 15 individuals.
Killer whales are considered to be some of the most social marine mammals. They live in groups ranging from 5 to 40 individuals, led by the oldest and most experienced female. Despite this, incidents where they attack vessels, such as yachts or catamarans, are becoming increasingly common.
The Spanish maritime rescue service reported that the killer whales sank the yacht after ramming it in Moroccan waters in the Strait of Gibraltar. How many of these marine mammals were involved in the attack is uncertain.
Yacht sank in the region of the Strait of Gibraltar
According to information provided by Reuters, the yacht named "Alboran Cognac" was 15 metres long.
Witnesses on the yacht described violent impacts to the hull and rudder before the water started to flood. They immediately called the rescue services. A nearby tanker came to their aid, took them on board, and transported them to a safe place. Despite the efforts, the yacht sank.
Killer whales on the attack, scientists seek answers
This was not the first attack in the region of the Strait of Gibraltar. Researchers believe that the Iberian killer whales comprise about 15 individuals.
Researchers are trying to understand why this happens. According to their theories, it may be a manifestation of the mammals' curiosity or a desire to eliminate a competitor. Killer whales may perceive yachts or catamarans as rivals in the fight for access to food.
In the scientific journal "Marine Mammal Science," researchers catalogued 49 instances of human contact with killer whales in 2020.
