ventral造句
31 The ventral interradial areas are skin covered with a coating of granules. 32 The plates of the ventral interradial areas are not as coarse as those on the dorsal surface. 33 The distal ventral arm plates are more pentagonal with an obtuse proximal angle and a wide convex distal edge. 34 The ventral arm plates are pentagonal with an acute proximal angle, a slightly indented distal edge, and separated from one another. 35 Where necessary the ventral view is supplemented with drawings of the disk armament, arm spines and lateral views of the arms. 36 The ventral arm plates are keeled rounded pentagonal to nearly square in shape and contiguous. 37 The ventral interradial areas are also covered with spinelets although the extent and density of covering varies. 38 The ventral arm plates are pentagonal with the distal edge rounded and contiguous at least proximally. 39 Ventral interradial areas are covered by many quite small plates but granules are not present. 40 The ventral interradial areas are also covered with granules although perhaps not as densely as the dorsal surface. 41 Their armour consisted of large dorsal and ventral oval shields surrounded by a series of smaller plates. 42 The ventral arm plates are pentagonal, the distal edge is convex but indented in the middle. 43 The coxal process is situated at the ventral extremity of the pleural sulcus. 44 The ventral arm plates are nearly pentagonal with a distinct convex distal edge textured with layers of calcite forming a concentric pattern. 45 The oral area is covered with skin, often with small granules, which extends on to the ventral surface of the arms. 46 The ventral interradial areas are covered with large plates like those of the dorsal surface, spinelets may be present. 47 The ventral interradial areas have similar armament to the dorsal side. 48 The ventral interradial areas are covered with small plates armed with simple rods like those of the dorsal surface. 49 The ventral arm spines are more rugose than the dorsal ones and slightly curved or sabre shaped. 50 The ventral ones are slightly flattened and very rugose; the dorsal ones appear smooth or finely rugose. 51 The ventral interradial areas are partially naked, but in some large specimens often covered with overlapping plates. 52 The ventral interradial areas are also covered by spinelets which are slightly smaller than those of the dorsal side. 53 The ventral interradial areas are covered by plates similar to those on the dorsal surface. 54 The ventral part of the arms does not have the small granules found in G. caputmedusae. 55 The ventral arm plates are pentagonal often with a rounded distal edge, and are separated. 56 The ventral interradial area is covered by similar spinelets to the dorsal side. 57 The ventral arm plates are rectangular contiguous with their lateral edges indented. 58 Ventral arm spins may be slightly flattened and in some the arm spine may be curved. 59 The ventral interradial areas are covered by plates and granules like those of the dorsal side. 60 The ventral arm plates are small, pentagonal with a rounded distal edge, sometimes the distal edge is indented.
