FIGURE 7 in New species of Crella (Pytheas) Topsent, 1890 and Crellomima Rezvoi, 1925 (Crellidae, Poecilosclerida, Demospongiae) from Chilean shallow and Argentinean deep waters, with a synthesis on the known phylogenetic relationships of crellid sponges

FIGURE 7. Crella (Pytheas) santacruzae Fernandez, Gastaldi, Thompson & Hajdu, sp. nov.: skeleton (A–F) and spicules (G–S, in SEM and light microscopy) of the holotype―ZIN 12081 (A, D–E, G–N) and paratype―ZIN 12082 (B–C, F, O–S). A, transverse section. B, transverse section. C, transverse section (another section). D, tornotes in bouquet and ectosomal acanthostyles scattered and making a continuous layer at the ectosomal region. E, bouquet of tornotes and ectosomal acanthostyles. F, tornotes in bundles and ectosomal acanthostyles at the ectosomal region. G, tornotes (strongyle-like shape). H, extremities of the tornotes. I, tornotes (in light microscopy). J, extremities of the tornotes with slightly rough appearance due to very small spines. K, choanosomal acanthostyles. L, choanosomal and ectosomal acanthostyles (in light microscopy). M, ectosomal acanthostyles. N, arcuate isochelae. O, tornotes (strongyles-like shape) and ectosomal acanthostyles. P, extremities of the tornotes. Q, choanosomal acanthostyles (in light microscopy). R, ectosomal acanthostyles. S, arcuate isochelae. Scale bars: A = 500 µm; B–C = 200 µm; D–G = 100 µm; H = 10 µm; I= 100 µm; J = 10 µm; K–L = 100; M = 50 µm; N = 20 µm; O = 100 µm; P = 10 µm; Q = 100 µm; R = 50 µm; S = 20 µm.
