Finbacks are the second largest animal to ever live on earth.
The average length maybe 50 to 60 feet with the record in the North Atlantic being 79 feet and the Antarctic record being 88 feet. Finbacks have been a harder whale to study as they can be very fast swimmers and travel a great distance under water. For example, this past summer we were with two finbacks that made a twelve minute dive and came up over a mile away. Also they do not show the under side of their tail when they dive down as humpback whales do. Yet, Allied Whale proved that you can tell them apart largely through fin shape.
