Notes: Prior to reforms of the Marine Mammal Protection Act (MMPA) in 1994, holders of marine mammals for public display were required to submit necropsy reports (animal autopsy

reports) for deceased animals, making the documents available to the public and scientificcommunity. Presently, marine mammal parks in the U.S. are only required to provide a “cause

of death” to the National Oceanic and Atmospheric Administration (NOAA) National MarineFisheries Service (NMFS) which maintains Marine Mammal Inventory Reports (MMIR).

Details of marine mammal deaths are now a closely guarded secret at U.S. entertainmentfacilities.

The Orca Project acquired the following documents from the National Marine Fisheries Service(U.S.A) via the Freedom of Information Act for deaths that occurred prior to implementation of the 1994 MMPA changes.
