Killer whale morphology - Variation in morphology of killer whale ecotypes

We are using elliptic Fourier analysis to determine the patterns of variation in morphology of dorsal fin shape, saddle patch shape, and eye patch shape of resident, transient, and offshore killer whales in the northeastern Pacific ocean. We will also be looking for evidence of genetic variation underlying these patterns in southern resident killer whales.
Morphology and heritability of morphol...

本研究采用椭圆傅里叶分析技术，旨在揭示东北太平洋地区常驻、过渡及离岸虎鲸的背鳍形态、鞍部斑纹形态及眼斑形态的变异模式。同时，我们亦将探寻这些模式背后南常驻虎鲸遗传变异的证据。
