Condylactis gigantea

Figure 2. Relative toxicity (LD50 and LD qq) estimates for actiniid sea anemone toxins upon crabs (Carcimis maenas) and mice. Values for Anemonia sulcata (As) and Anthopleura xanthogrammica (Ax) toxins are from ref. 24 data for Condylactis gigantea and Phyl-lactis flosculifera toxins are unpublished (Kem). The arrows indicate that the real mouse LD q values for Cg II and Pf II must exceed the values indicated in the Ogure. Although insufficient data are presently available to quantitatively define a relationship between mammalian and crustacean toxicity, it seems that there is usually an inverse relationship, which may be approximately defined by the stipple zone.

Kentolysin Compared to Heliantholysin. Stoichactis helianthus occurs in the Caribbean region whereas another species, Stoichactis kenti is distributed in the Indo-Pacific area. The latter produces a toxin, kentolysin, that is similar to, but not identical with heliantholysin (6). The amino acid compositions of the two polypeptides show a distinct resemblance but appear to differ significantly in number of residues of lysine, methionine, tyrosine and histidine. IgG from a rabbit immunized against heliantholysin neutralizes both heliantholysin and kentolysin, but neutralization of the homologous toxin is more efficient (Table III). It can be seen that in the concentrations used, the IgG failed to neutralize the related lytic peptides of Condylactis gigantea and Epiactis prolifera.

Figure 3 Purple-tipped giant sea anemone-Condylactis gigantea. Condylactisgigantea is a common Caribbean anemone that is not always purple-tipped . Several organisms can find refuge by inhabiting near a sea anemone, as the anemone shrimp (Periclimenes brevicarpalis) shown in the picture. Photo courtesy of Susan Davis, Key Largo, FL.
