In the Tardent and Weber scheme, there are seven types ([B.sub.1]-[B.sub.7]) of bipolar neurons, only two of which are ciliated ([B.sub.3] and [B.sub.4]).
The cell bodies of the monopolar and bipolar neurons appeared to be flask shaped, similar to the cell bodies described for neurons in the bipinnaria larvae of an asteroid (Lacalli et al., 1990).
One was a population of bipolar neurons. These cells, which had cell-body diameters of 10 to 15 [[micro]meter] and axon diameters of 0.5 to 2 [[micro]meter], were at least 0.6 mm long and formed a loose nerve net [ILLUSTRATION FOR FIGURE 1D OMITTED].
