1 The ventral arm plates are not contiguous. 2 Note the downturned wingtips and large ventral fin. 3 The ventral interradial areas are covered with small plates. 4 The ventral interradial areas are completely naked. 5 The ventral interradial areas are also covered by naked skin. 6 The ventral arm plates are wider than long, pentagonal with an obtuse proximal angle and a slightly convex distal edge. 7 The lateral and ventral arm plates have distinctive transverse ridges most noticeable in dry specimens. 8 The ventral interradial area is also covered with granules, if spinelets are present they are usually confined to the distal edge. 9 The ventral arm plates are pentagonal, broader than long and separated. 10 The lateral and ventral arm plates have distinctive transverse ridges most noticeable in dry or nearly dry specimens. 11 The subsequent ventral arm plates are pentagonal to bell shaped, separated with a wide curved distal edge and indented lateral edges. 12 Its ventral fins are enlarged and flattened to form suckers on the underside of the body. 13 The proximal ventral arm plates are approximately trapezoidal with a wide convex distal edge, they are contiguous with one another at least proximally. 14 The ventral interradial areas are covered with large plates sometimes bearing a spinelet. 15 The first ventral arm plate is pentagonal with the lateral edges raised forming a boundary lip to the second oral tentacle pores. 16 The Ventral Nerve-Cord consists of a series of ganglia lying on the floor of the thorax and abdomen. 17 The ventral arm plates are an irregular pentagonal or hexagonal shape, often keeled, with the distal edge sometimes indented. 18 The ventral arm plates are irregularly rectangular with indented lateral edges and a rounded distal edge; they are contiguous at least proximally. 19 The ventral interradial areas are also covered by low granules. 20 The ventral interradial areas are similar to those of the dorsal side but the scales are usually more conspicuous. 21 The ventral arm plates are pentagonal with a wide distal edge, and contiguous on proximal arm segments. 22 The ventral interradial areas are covered by scales like those of the dorsal surface but the rod-like spinelets are usually smaller. 23 The ventral interradial areas are also covered with spinelets which are more nearly granular than those of the dorsal side. 24 The ventral arm plates are pentagonal nearly triangular with a very wide distal edge; the distal edge may project slightly midradially. 25 The central nervous system is divisible into the brain or cerebral ganglion, the suboesophageal ganglion and the ventral nerve-cord. 1. 26 They frequently can be seen perched on a rock and propped up on their ventral fins as if surveying their little world. 27 All the patients were treated in the prone position, with the shock waves entering from the ventral side. 28 Locomotion is effected by undulating waves of muscle contraction and relaxation which alternate on the dorsal and ventral aspects of the worm. 29 The male is a little larger than the female and has very bright orange ventral fins when in breeding colouration. 30 The dorsal arm spines are the longest nearly two arm segments in length, the ventral arm spines are much shorter.
