Summary: | The morphology of extrinsic gasbladder musculature of Sebastes marinus was examined to provide criteria that may be useful in discrimination of the three Northwest Atlantic redfishes, particularly for small individuals. The investigation revealed that S. marinus has a short, wide L-shaped gasbladder muscle which is generally tricipital. The most frequent pattern of tendons extending posteriorly was attachment of dorsal head tendons to ventral rib 2, passage of central head tendons between ribs 2 and 3, and passage of ventral head tendons between ribs 3 and 4. This is significantly different from the long, narrow gasbladder muscle of beaked redfishes, with |
