Pod of Dolphins in Rare Incident of Killing Baby Calf off Welsh Coast
In an extraordinary and heartbreaking event, a group of boat trippers off the Welsh coast witnessed a pod of dolphins attacking and killing a baby calf. The incident occurred during a wildlife watching trip near New Quay, Cardigan Bay, where a group of passengers, along with intern Dylan Coundley-Hughes from the Sea Watch Foundation, observed the rare behaviour.
The remarkable sighting was captured on video, showing four bottlenose dolphins aggressively hunting down and throwing the common dolphin calf into the air. This interspecific infanticide, as described by Dylan, is an extremely uncommon occurrence, as bottlenose dolphins are usually known to prey on porpoises rather than attack common dolphin calves.
The Sea Watch Foundation, a charity dedicated to the conservation of marine mammals in British waters, has been monitoring the dolphin population in Cardigan Bay for over two decades. This incident sheds light on the complex behaviour of bottlenose dolphins and their interactions with other cetacean species in the region.
Sarah Michelle Wyer, a guide and photographer for dolphin spotting boat trips in west Wales, expressed her surprise at witnessing such rare behaviour. While it is common for bottlenose dolphins to attack porpoises, the attack on a common dolphin calf was a first for her. The sighting has provided researchers with valuable insights into the behaviour of these marine mammals.
Cardigan Bay is home to a resident population of bottlenose dolphins, with an estimated 200 to 300 individuals living in the area. The conservation efforts of organisations like the Sea Watch Foundation are crucial in protecting these marine species and understanding their ecological dynamics.
Researchers, such as Katrin Lohrengel from the Sea Watch Foundation, emphasise that while bottlenose dolphins are often perceived as friendly and playful animals, instances of infanticide and aggression towards other species have been documented. The aggressive behaviour observed in this incident highlights the complexity of dolphin social dynamics and interactions in the wild.
The post-mortem examination of the common dolphin calf by the UK Cetacean Strandings Investigation Programme will provide further insights into the circumstances surrounding the attack. Understanding the factors that drive such aggressive behaviour among dolphins is essential for their conservation and management in the wild.
Overall, this rare and tragic event has provided researchers with a unique opportunity to study the behaviour of bottlenose dolphins and their relationships with other marine mammal species in Cardigan Bay. By documenting such incidents, conservationists can better protect these animals and their habitats from potential threats and disturbances.
In conclusion, the recent sighting of dolphins attacking and killing a baby calf off the Welsh coast serves as a reminder of the complex nature of marine ecosystems and the importance of ongoing research and conservation efforts to safeguard these charismatic and intelligent animals.
