Dead calf at Ynyslas was killed by another dolphin

By Caleb Spencer in Environment

A BABY dolphin which washed up dead on Ynyslas Beach in August was probably killed by another dolphin, experts have concluded.

The 1.45m-long bottlenose dolphin was found on 5 August by Ali Chedgy, assistant reserves manager at Natural Resources Wales’ Ynyslas Dyfi National Nature Reserve, who was able to recover the dolphin and keep it in frozen storage.

A post-mortem examination was carried out by the Cetacean Strandings Investigation Programme, a UK, Wales and Scottish government-funded body established in 1990 to investigate live and dead marine strandings.

CSIP said they found evidence the dolphin was a calf, likely less than a few weeks old, and had injuries consistent with attack by another dolphin.

A CSIP report on its Facebook page said: “The post-mortem found conspecific rake-marks on the head (i.e. made by the same species) and multiple areas of focal bruising to the abdominal region and body wall, which were considered to be consistent with traumatic point impacts.”

CSIP thanked Miss Chedgy, whose swift action they say allowed a post-mortem to take place.

Miss Chedgy told the Cambrian News: “I got the call after Borth carnival to go and investigate a possible stranding.

“I identified the dolphin as a young bottlenose and contacted the CSIP, who said they’d come and collect it, but wouldn’t be able to get to us until the next day at the earliest.

“As the tide was coming in, we removed it from the shore, and stored it on site for 24 hours, until it could be transferred to cold storage elsewhere.

“Although upsetting to see, dead marine mammals are not an uncommon sight on our coastline."
