FIGURE 4 in A new species of Diadumene (Actiniaria: Diadumenidae) from the subtropical coast of Brazil

FIGURE 4. Representative undischarged cnidae of Diadumene paranaensis n. sp. from each region of the body. Dashed line along upper edge is the scale. Letters on left and right sides refer to the different types of cnidae, as follows: a = Macrobasic pamastigophore; b = Atrich; c = Holotrich; d, g, j, k, m, n, o, r = Microbasic p-amastigophore; e, h, i, l, p, t = Basitrich; f = Spirocyst; q, s = Microbasic p-mastigophore. Difference between atrichs and holotrichs is based on England (1991).
