ProppedOne was first photographed in 2005 and has been photographed consistently since then. ProppedOne has been identified on both the right and left sides and is a presumed mother based on photographs with an accompanying calf. ProppedOne has unique injuries indicating that at some point it was possibly entangled or was involved in a ship strike.
