Subject: pilot whale or dolphin?

Dolphins, porpoises and large whales are officially all whales.  The Orca or 
killer whale is a member of the dolphin family.  Pilot whales are also large 
dolphins, and received their name centuries ago because they seemed to 
"pilot" vessels into port.

Good question.  Thank you
