Quantitative histology Feeding tentacle
Feeding tentacles had an average of 114.7 cnidae per tentacle tip cross section (equivalent to a 1.00 unit cnidom, n = 6). Of these 114.7 cnidae, 57.3% were spirocysts, 26.5% were microbasic p-mastigophore nematocysts, 5.2% were basitrich nematocysts, 2.2% were gastrodermal cnidae, and 9.8% were cnidoblasts (Fig. 9). The H. luciae feeding tentacle complement of spirocysts (at 57%) of the tentacle cnidom is lower than those reported by Purcell (1977) for Metridium senile (at 80%) and Schmidt (1982) for Anemonia sukata (at 68%) but is in general agreement with the findings of Bigger (1982) for four anemone species. In this study, Bigger reported that the spirocyst complement ranged from 49% to 79% of the feeding tentacle cnidom.
Stage 1 intermediate catch tentacle
Stage 1 intermediate catch tentacles had slightly fewer cnidae than feeding ten tacles with an average of 104.6 cnidae per tentacle cross section (104.6/1 14.7 = a
