FIGURE 3 in Podocoryna loyola, n. sp. (Hydrozoa, Hydractiniidae): a probably introduced species on artificial substrate from southern Brazil

FIGURE 3. Phylogenetic hypothesis derived from maximum likelihood analysis based on a fragment of the 16S mitochondrial gene (540 bp). The sequence of the species described here is referred to "Podocoryna loyola Brazil." The numbers above and below the branches support values are obtained per 100 bootstrap replicates.

FIGURE 2 in Podocoryna loyola, n. sp. (Hydrozoa, Hydractiniidae): a probably introduced species on artificial substrate from southern Brazil

FIGURE 2. Diagram showing the main morphometric measurements taken of the hydromedusa and some of its most characteristic structures. Dmax: maximum diameter of the umbrella; Hmax: maximum total height of the umbrella; Dmar: diameter of the umbrella margin; Dape: diameter of the opening to the subumbrellar cavity; Hmes: height of the mesoglea in the apical region; Hman: height of the manubrium; Thmes: thickness of the mesoglea near the edge. (modified from Tronolone 2001).

FIGURE 11 in Description and life cycle of the hydrozoan Hydractinia uniformis, sp. nov. (Cnidaria: Hydrozoa: Hydractiniidae), from the coast of southeastern Brazil

FIGURE 11. Schematic side view of a colony of Hydractinia uniformis, sp. nov. Note: the polyp tentacles are slightly retracted; the polyp on the right side is contracted and has frustules and medusa buds; the polyp on the left side has an older medusa bud. Scale = 500 µm.
