#MarineWildlife - Seven dolphins and two beaked whales have stranded on beaches in the northwest in events described as "unusual" by the Irish Whale and Dolphin Group (IWDG).

On the Mullet Peninsula, a group of seven common dolphins - comprising five adults and two juveniles - live stranded at Tarmon Beach on Sunday 12 May.

Though initial attempts to refloat them were successful, one of the juveniles was later found dead and the other was euthanised due to poor health.

Meanwhile in Donegal, the fresh carcass of a female True's or Sowerby's beaked whale was found on Sunday evening on Five Fingers Stand at Inishowen - some days after a reported live stranding of a Sowerby's beaked whale on the Welsh coast.

The Inishowen stranding was followed yesterday 14 May by the discovery of a dead beaked whale calf at Trawbreaga Bay, in what is believed to be a connected stranding.

Samples of the adult female were taken in order to confirm the species, either of which would mark a rare cetacean record for Ireland - the first since 2009.
