"Check out this spectacular video orca hunting a shark in the Mahurangi Harbour. The shark is a broadsnout sevengill shark (Notorhynchus cepedianus) – identified by Clinton Duffy, shark researcher in NZ.
This footage also features some well known and distinctive New Zealand killer whales catalogued by Dr. Ingrid Visser: A1 (NZ1) and Ben (NZ101)!
Female orca A1 was the first orca to be catalogued in New Zealand. She was first photographed in 1977, when she was already an adult – this would make her born around 1966. The top of her dorsal fin is missing due to an incident with a fishing line, cut at an angle.
Ben is an adult male with some story, having been stranded and rescued on Northland's Mangawhai Beach in June 1997. One year later he was run over by a boat and hurt badly. The boat propeller sliced his dorsal fin, half of the fin now folds to the left.
The guys filming were very excited capturing this scene: *WARNING* swear words - please watch with sound off if children are present."
