The use of beak measurements to separate two morphologically similar species of the squid family Ommastrephidae is discussed. Discrimination is shown to be possible with a high degree of certainty using various ratios of measurements. Relationships between a durable beak measurement and both body weight and dorsal mantle length are presented for each species. The applications and possible extensions of the separation methods are discussed.
