Figure 5. Adeonella pallasii (Heller, 1867). (A–E) Different aspects from the same branch. Off Prvić, 20 m depth. (A) Young portion. Note the different shape and size of zooids in the lateral rows. Scale bar: 500 µm. (B) Old portion with less differentiated and more diamond-shaped zooids. Scale bar: 1 mm. (C) Lateral view showing the zooids forming the margin of the branch with their usually paired, inclined peristomial avicularia. Scale bar: 1 mm. (D) Young zooids, detail of (A). Note the prominence of frontal knobs. Scale bar: 500 µm. (E) Old zooids, detail of (B). Scale bar: 500 µm. (F) Zooids with deepened secondary orifices and spiramina due to secondary calcification. Frontal avicularia appear on some zooids. Apulian shelf, 80–100 m. Scale bar: 500 µm. (G,H) From Jabuka Shoal, 32 m depth. (G) Branching point with an axillary kenozooid. Scale bar: 500 µm. (H) Growing tip with newly budded zooids and their primary orifices rapidly hidden by the overgrowing peristomial bridges. Scale bar: 500 µm. (I) Primary orifice. Scale bar: 50 µm. (L) Detail of the sinus. Scale bar: 20 µm.
