The animal was an injured young Cuvier’s beaked whale, or Ziphius cavirostris, according to Arion, a research organization that provides veterinary care for stranded cetaceans.
He said two specialized veterinarians, a specialized veterinary nurse and four aid organizations had been brought in to try to save the whale.
The animal was found to have suffered a severe injury to its lower jaw and mutiple superficial wounds to its body.
The animal was initially sighted in shallow water Thursday in the nearby area of Vouliagmeni, and divers had been called in to lead it out to sea.
“The prognosis unfortunately isn’t good,” Amyras said, noting that the whale’s natural habitat was in deep water.
