A Caretta caretta is pictured yesterday recovering in the Aquaworld aquarium in Crete, the largest of its kind in the Balkans, after receiving medical treatment for swallowing a fishing hook. The sea turtle is to stay at the aquarium until it is healthy enough to be released back into the sea. Aquaworld, on Crete’s Hersonissos peninsula, takes in sick and injured marine mammals for treatment and accommodates abandoned pets.
