Translated from the Reddingsteam Zeezoogdieren Zuidwest in Zeeland province in the Netherlands:
Nieuwvliet, 25 December 2017 – this afternoon RTZ-Zuidwest received another report of a stranded ocean sunfish. This time between beach pavilion De Boekanier and Nieuwvliet.
RTZ-southwest has gone that way but due to the falling darkness and the rising water, the sunfish was no longer found. It is possible that it will be found tomorrow morning so that it can still be recovered.
