Fig. 3 in Echinoderes galadrielae Grzelak & Sørensen 2022, sp. nov.

Fig. 3. Gill morphology in T. microlepis was observed in the control group, the hypoxic group and the restricted group after 28 days. A, E, and I was the 1st gill; B, F, and J was the 2nd gill; C, G, and K was the 3rd gill; D, H, and L was the 4th gill, which had the larger vessels in the lamellar base. A-D show gills in the control group; E-H show gills in the hypoxic group; I-L show gills in the restricted group. Significant morphological changes were observed in the 4th gill in the restricted group after 28 days (L). The rest of the groups showed no apparent morphological modification among gills. F: filament, L: lamellar, RBC: red blood cell. Scale bar = 50 μm
