Grey seals in UK waters are displaying unusual and worrying behavior: they have begun attacking and feeding on dolphins and porpoises, raising concerns for human safety.
Wildlife conservation groups have reported several recent attacks, some of which have been caught on camera. In one incident in the Irish Sea off the coast of Dublin, a large seal was seen grabbing a bottlenose dolphin with its teeth.
The first suspected case of a grey seal killing a dolphin has also been recorded in Wales. Analysis showed characteristic injuries, known as "spiral wounds", consistent with seal bites.
Similar events have been reported in other areas, including Devon, raising concerns about a change in the behavior of these marine predators.
Experts warn that seal bites can be very dangerous to humans. The infections caused by bacteria in their mouths are so serious that in some cases they can lead to amputation.
Another risk for those who have contact with injured animals is the infection known as "seal toe," which can progress to sepsis if left untreated.
There are currently around 120 grey seals living along British coasts. Researchers say there is growing evidence that these animals feed on a wider range of marine life than previously thought.
However, this behavior is not widespread across the population. It is believed to be associated with certain individuals, who may be "learning" this way of hunting and transmitting it to others.
Scientists suspect that the attacks occur suddenly, often from below, leaving the dolphins unable to react.
So far, about 20 seals have been identified that are suspected of being involved in these attacks, distinguishable by the characteristic marks on their bodies. Experts warn that this phenomenon could gradually spread if it continues to be learned by other individuals. /GazetaExpress/
