Localization of a purported chemoreceptor involved in triggering cnida discharge in sea anemones.
I chose spirocysts for this first study of cnida microscaling for several reasons.
Here I describe scaling of one adhesive cnida type (spirocysts) from two different tissues (ectoderm of the feeding tentacles and acrorhagi) of two sympatric anemones that have contrasting diets, growth forms, and social structures.
Cnida scaling (and the scaling of cellular secretions, generally) may typically reflect the underlying phenomenon of cell scaling.
Here I apply a series of generally conservative and robust statistics to describe and compare data on cnida size as a function of polyp size.
In fact, mean cnida lengths are significantly correlated with body size for all four of his acontial cnida populations; and mean capsule widths are significantly correlated with body size for 1 of the 4 (Spearman rank correlation, our Table 4).
8] M D-600 appears to inhibit cnida discharge from Type B CSCCs in response to glycine.
Control of cnida discharge: factors affecting discharge of cnidae.
As a part of our on-going investigation into the mechanisms that regulate cnida discharge, we have developed methods to quantitate discharging cnidae under conditions in which the eliciting stimuli and the target surfaces are defined.
Under conditions where cnida adhesion exceeds tentacle adherence, the contribution of each kind of cnida to adhesive force is the product of the number of cnidae discharged and the force required to remove one such cnida from the tentacle (i.
Because external calcium is required for cnida discharge in sea anemones (Blanquet, 1970; Lubbock and Amos, 1981; Thorington and Hessinger, 1992; Watson and Hessinger, 1994b), we attempted to inhibit discharge by either pre-treating anemones for 90 min in Ca-free ASW or by following the pre-incubation in Ca-free ASW or ASW with 10% formalin for 5 min at 4 [degrees] C or at room temperature before measuring adhesive force and cnida discharge.
Cnida capsules from anthozoans are prolate ellipsoidal in shape.
