Figure 4 in Digging with 'hands': observations of food capture in the flying gurnard Dactylopterus volitans (Linnaeusı 1758)
Figure 4. Above: still image collected from video Sequence 1 (0.067 s later than the image shown in Figure 2). White arrow indicates direction of movement of the anterior pectoral fin. At this stage of the movement cycle, the anterior rays have twisted downward against the substratum and are depressed with respect to the posterior rays; the fin is moving downwards, backwards and laterally. Below: line drawing of outline of fish and its fins.
Figure 3 in Digging with 'hands': observations of food capture in the flying gurnard Dactylopterus volitans (Linnaeusı 1758)
Figure 3. Above: still image collected from video Sequence 1. The fish is viewed from the side and slightly above/behind. White arrow indicates direction of movement of the anterior pectoral fin. At this stage of the movement cycle, its anterior fin rays are elevated and the posterior rays depressed; the fin is being moved forwards and medially. The distal ends of the fin rays trail and are curved. Below: line drawing of outline of fish and its fins.
Figure 2 in Digging with 'hands': observations of food capture in the flying gurnard Dactylopterus volitans (Linnaeusı 1758)
Figure 2. Close-up of proximal ends of right anterior and posterior pectoral fins of the preserved specimen of D. volitans viewed from the lateral aspect. The robust unsegmented second fin ray is arrowed; the curved white line indicates the thickness of this fin ray at its articulation with the pectoral girdle, This figure also illustrates the heavy armour and spines of the skull.
Figure 1 in Digging with 'hands': observations of food capture in the flying gurnard Dactylopterus volitans (Linnaeusı 1758)
Figure 1. (a) Dorsal view of adult live specimen of D. volitans moving over a sandy substratum (in Florida) with the pectoral fins expanded. This illustrates the separate anterior and posterior pectoral fins (single field from https://www.youtube.com/watch?v=-YaDmwvGICE). (b) Ventral view of preserved 40 cm specimen of D. volitans. (c) Close-up of proximal ends of the left pectoral and pelvic fins of the preserved specimen viewed from an antero-ventro-lateral aspect. Note that the fin rays of the pelvic fin are all unsegmented, as are many of those of the posterior pectoral fin. The anterior pectoral fin is largely composed of segmented pectoral rays, but its anterior edge features a strong unsegmented second fin ray.
