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.
m], intrinsic adherence of mastigophore nematocyst; [i.
quadrumanus consists of three types of nematocysts, isorhizas (ovoid and ellipsoid), microbasic euryteles and microbasic mastigophores (Calder & Peters, 1975; Carrette et al.
2a), and no euryteles or mastigophores were observed.
We infer from our results that the capsule wall and the apical flaps of a mastigophore of Metridium each consists of two layers and that each layer is continuous between capsule and flaps.
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.
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.

of nematocysts 2-4h-old larvae, 1-day-old larvae 0.
m] values of mastigophore nematocysts from both Type B and Type C CSCCs are constant, (ii) the value of [[i.
Briefly, the gelatin coating of the probes is enzymatically digested to release the nematocysts of the discharged mastigophores.
Our findings indicate that as long as mastigophores are able to penetrate the surface of prey, cnida-mediated attachment of prey to tentacles is provided predominantly by mastigophore nematocysts, not by spirocysts.
After being used to measure adhesive force, the gelatin coating of the probe tips are enzymatically digested to release the discharged mastigophore nematocysts.
