Fig. la,b. Nematocytes isolated by heat dissociation. Note in a the presence of a distinct cnidocil (arrowhead), that in b is surrounded by stereocilia (arrowhead)
Fig.2a,b. a Nematocyte isolated by SCN- treatment. Note the absence of cnidocil at the apical end (large arrowhead) and the
centrally placed girdle (small arrowhead). b Segment of tentacle in which the treatment of SCN- was blocked once the protrusion of nematocytes was observed. Note that cnidocil was still present in partially extruded nematocytes (arrowheads)
