FIGURE 4 in Coralliidae (Anthozoa: Octocorallia) from the INDEMARES 2010 expedition to north and northwest Spain (northeast Atlantic), with delimitation of a new species using both morphological and molecular approaches

FIGURE 4. (A) Cortical sclerites of Corallium occultum n. sp., paratype (MNCN 2.04/1130). (B) Box plots indicate the width, height, and width/height ratio of double clubs from Corallium johnsoni (Gray, 1860), NHM 1933.3.13.55 and SMF 2426; Corallium medea Bayer, 1964, USNM 52512 (holotype) and USNM 52513 (paratype); Corallium occultum n. sp., MNCN 2.04/1128 (holotype) and MNCN 2.04/1130 (paratype). The box delimits the first and 3rd quartile, the horizontal line represents the median, and the whiskers delimit values that are within 1.5 x the inter-quartile range; values outside that range are represented by circles and considered as statistical outliers. (C) Mean (± one standard error, n= 40) of width, height, and width/ height ratio of double clubs. Means within a column (in small letter) followed by the same letter are not significantly different based on multiple comparisons (at alpha = 1% significance level).
