Record #179971:

A dwarf form of killer whale in Antarctica / Robert L. Pitman, Wayne L. Perryman, Don LeRoi, Erik Eilers.

Title: A dwarf form of killer whale in Antarctica / Robert L. Pitman, Wayne L. Perryman, Don LeRoi, Erik Eilers.
Author(s): Pitman, Robert L.
Perryman, Wayne L.
LeRoi, Don.
Eilers, Erik.
Date: 2007.
In: Journal of Mammalogy. (2007.), Vol. 88(1) (2007)
Abstract: Comparison of aerial photogrammetry of Type C killer whales in southern Ross Sea in January 2005 with data from Soviet whaling ships in 1960s and 1970s shows that total length of inshore, fish-eating whales was significantly less than that of Type A offshore mammal-eating killer whales. Discusses possibility that size dimorphism could result in reproductive isolation between sympatric ecotypes, which would be consistent with hypotheses of multiple species of killer whales in Southern Ocean proposed by Soviet researchers in 1980s.
