FIGURE 4 in Two new desma-less species of Theonella Gray, 1868 (Demospongiae: Astrophorida: Theonellidae), from the Great Barrier Reef, Australia, and a re-evaluation of one species assigned previously to Dercitus Gray, 1867

FIGURE 4. Summaries of statistics for sets of measurements of microrhabds from Theonella deliqua n. sp., Theonella maricae n. sp. and Theonella xantha (Sutcliffe, Hooper and Pitcher, 2010) n. comb. The boxes for each species include the minimum, maximum, mean, standard deviation and variance. A boxplot has been used to demonstrate the distributions of the means of the measurements for each species and to indicate significant differences among them. Outliers are indicated by asterisks (*). The ranges of the measurements for T. deliqua and T. xantha can be seen to be approximately equivalent, and are normally distributed. Stronger skew and Kurtosis are shown for the measurements for the specimens of T. maricae. Most measurements of the microrhabd length for T. maricae greatly exceed those of the other two species, as illustrated in the boxplot.Published as part of Hall, Kathryn A., Ekins, Merrick G. & Hooper, John N.A., 2014, Two new desma-less species of Theonella Gray, 1868 (Demospongiae: Astrophorida: Theonellidae), from the Great Barrier Reef, Australia, and a re-evaluation of one species assigned previously to Dercitus Gray, 1867, pp. 451-477 in Zootaxa 3814 (4) on page 459, DOI: 10.11646/zootaxa.3814.4.1, http://zenodo.org/record/491927
