"The Florida panther is tawny brown on the back and pale gray underneath. It is one of 32 Puma concolor subspecies known by many names – puma, cougar, mountain lion, painter, catamount and panther."
Had a residence call in NM years ago that was for a Mtn Lion in a backyard tree. The best descriptor from the reporting party when asked by the dispatcher was a terse "I don't know what the hell it is other than A big Ass Cat".
Bingo. The Florida Panther was believed extinct until about 20 years ago, when a troubled homeless guy read about the extinction and wandered off into the Everglades, living off the land. He finally spotted his first "extinct" panther -- as he bent down to drink some water, he glanced up and across the standing water a panther was doing the same, while keeping an eye on the man.
