FIG. 7 in Use of cnidae in taxonomy: implications from a study of Acrozoanthus australiae (Hexacorallia, Zoanthidea)
FIG. 7. Scattergrams of nematocyst capsule width and length measurements. (A) Collection from Indonesia, the various types within dotted ellipses; (B) collection from Queensland with the data points superimposed on the dotted ellipses taken from (A).

Origins: Act, actinopharynx; Fil, filament (undifferentiated); Lfil, lower part of filament; Tbas, basal portion of tentacle; Tent, Tentacle (undifferentiated); Ttip, tip of tentacle; Scap, scapus; Ufil, upper part of filament.

FIG. 3 in Use of cnidae in taxonomy: implications from a study of Acrozoanthus australiae (Hexacorallia, Zoanthidea)
FIG. 3. The effect of sample size on nematocyst capsule length range in 15 samples of Acrozoanthus australiae from Indonesia. All samples are from the same clone.

Large increases occurred between n~50 and n~75; only in sample 4, 5.0 was there no increase in range with increasing sample size.
