Observed and photographed by my colleague Mike Morrison. A rare find usually associated with deep water in the tropics. This specimen was 3 m in length, 300 mm from spine to belly and 75-100mm thick and was estimated to weigh around 50 kg.
Washed ashore at Madaket Beach, Nantucket and reported in The Inquirer and Mirror on 5/11/15. See http://www.ack.net/Oarfishwashesashore050615.html
I thought it prudent to record to iNat in case no one else did.
