This implies that Type Bs and Type Cs contribute equally toward prey killing during that period and, by extension, mastigophore nematocysts from Type Bs and Cs are equally effective in killing brine shrimp nauplii.
cnidocyte/supporting cell complex; [i.sub.m], intrinsic adherence of mastigophore nematocyst; [i.sub.s], intrinsic adherence of spirocysts; [n.sub.m], number of discharged mastigophore nematocysts: NANA.
A TEM image of a mastigophore nematocyst at an early stage of formation reveals an immature tubule in a moderately electron-dense matrix enclosed by a thin double-walled capsule (Fig.
Despite this evidence, the relationship between capsule wall and tubule was still unsettled: figure 4 of Godknecht and Tardent (1988: 88) illustrates a mastigophore of Anemonia sulcata, the caption of which states that what we interpret as the anchorage of the tubule is "where electron dense interna of the evaginating structures goes over into the less electron dense interna covering inner face of capsule." and that they considered to be a fourth layer of the capsule wall.
In their study of microbasic mastigophores of the sea anemone Anemonia sulcata (Pennant, 1777), Godknecht and Tardent (1988: p.
verrucosa countered by incorporating larger percentages of the penetrating microbasic mastigophore.
Flabellina verrucosa responded to the presence of Crossaster papposus with significantly increased incorporation of microbasic mastigophores (MM) and depressed uptake of heterotrichous anisorhizas (HeA) (Fig.
Flabellina verrucosa's increased incorporation of microbasic mastigophores from its cnidarian prey in the presence of the predators Crossaster papposus and Tautogolabrus adspersus is a unique example of such an interaction.
Abbreviations: Al, atrichous isorhiza; AT, aboral tentacle; D, desmosome; MM, microbasic mastigophore; S, stenotele.
The calculated Type B dose-responses of both mastigophore and spirocyst discharge are narrow and biphasic.
The dilution/recruitment model assumed that (i) the [i.sub.m] values of mastigophore nematocysts from both Type B and Type C CSCCs are constant, (ii) the value of [[i.sub.m].sup.c] is larger than the value of [[i.sub.m].sup.b], and (iii) the number of nematocysts discharged from Type C CSCCs is constant, (iv) while the number discharged from Type B CSCCs varies biphasically with increasing concentrations of chemosensitizer.
Mastigophore nematocysts were discharged with 30% gel-coated probes following exposure of the Carolina strain anemones to E[C.sub.100] doses of different sensitizers.
We measured the dimensions of mastigophore capsules discharged onto test probes from control anemones (i.e., discharged from Type C CSCCs) and from anemones chemosensitized at [K.sub.0.5] and [EC.sub.100] levels of various sensitizers (i.e., discharged from both Type B and Type C CSCCs in ratios ranging from 2:1 to 5:1, respectively).
2a), and no euryteles or mastigophores were observed.
After 5 days of hydration, we observed undischarged and discharged isorhizas, and a few euryteles were visible through the layer of tissue, but still no mastigophores were found (Fig.
