Fig. 48. Family Ophiactidae Matsumoto, 1915 in New species, redescriptions and new records of deep-sea brittle stars (Echinodermata: Ophiuroidea) from the South China Sea, an integrated morphological and molecular approach
Fig. 48. Family Ophiactidae Matsumoto, 1915, Maximum likelihood (ML) tree based on partial COI sequences (bootstrap support values were generated with rapid bootstrapping algorithm for 1000 replicates). Abbreviations: AUS = Australia; IC = Inter-Clade; NZ = New Zealand; PNG = Papua New Guinea; SC = Sub-Clade; SCS = South China Sea; TS = Tasman Sea.
Fig. 27. Ophiactidae Matsumoto, 1915 in Taxonomic analysis of the genital plates and associated structures in Ophiuroidea (Echinodermata)
Fig. 27. Ophiactidae Matsumoto, 1915, SEM, unless otherwise noted. A. Ophiactis savignyi (Müller & Troschel, 1842), genital plates in situ, micro-CT. B–L. Ophiactis abyssicola (M. Sars, 1861). B. adGP and adGP articulated. C. Radial shield, internal aspect. D–E. adGP, dorsal aspect. F. adGP, ventral aspect. G. abGP, abradial aspect. H. adGP, ventrolateral view (from other, smaller specimen). I. oGP in situ (arrowheads, digital image), oral shield removed. J. Oral shield, internal aspect. K. Madreporite, internal aspect. L. oGP. Scale bars: A, J–L = 0.1 mm; B–I= 0.5 mm.
FIGURE 2 in New light on the nomenclature, taxonomy, and biology of Hemipholis species (Echinodermata: Ophiuroidea: Ophiactidae)
FIGURE 2. Scatter plot for Hemipholis cordifera and Hemipholis gracilis, showing the relationship between the body size in terms of disk diameter, and shape of the second ventral arm plate characterized by the ratio between the ossicle's width and length.
FIGURE 1. Hemipholis cordifera and Hemipholis gracilis. A–C, H. cordifera, LACM 1999-26.2, 7.8 in New light on the nomenclature, taxonomy, and biology of Hemipholis species (Echinodermata: Ophiuroidea: Ophiactidae)
FIGURE 1. Hemipholis cordifera and Hemipholis gracilis. A–C, H. cordifera, LACM 1999-26.2, 7.8 mm disk diameter, from South Carolina; D–F, H. gracilis, LACM 1997-224.001, 7.8 mm disk diameter, from Panama; specimens preserved in ethanol. For each specimen, shown from left to right are: portion of disk in dorsal view, arrowheads indicating pairs of radial shields; basal arm joints on ventral side of disk, arrow indicating second ventral arm plate; basal arm joints in dorsal view, arrowheads indicating middle arm spines. Dorsal arm plates of both species are sometimes fragmented as is the case in Figure C. Scale bars = 1.0 mm.
FIGURE 3 in The widely occurring brittlestar Ophiactis savignyi (Amphilepidida: Ophiactidae) as an epibiont on loggerhead sea turtle, Caretta caretta
FIGURE 3. Ophiactis savignyi (Müller & Troschel, 1842) (CMNH-ZE 01692), disc diameters are 1.0 mm (A; different specimen from Fig. 2A) and 2.9 mm (B–D). A, aboral disc and proximal portion of arms, arrow heads indicate spines on disc edge; B, oral disc, part of jaws; C, lateral proximal portion of an arm, arrow heads indicate arm spines; D, aboral proximal portion of an arm. Abbreviations: D, dorsal arm plate; OP, oral papillae. Scale bars = 1 mm

FIGURE 2. Ophiactis savignyi (Müller & Troschel, 1842) (CMNH-ZE 01692), aboral view showing conspicuously variegated green and white body color, disc diameters are 1.0 mm (A), 2.2 mm (B), 2.0 mm (C), 2.5 mm (D), 1.8 mm (E).
FIGURE 1 in The widely occurring brittlestar Ophiactis savignyi (Amphilepidida: Ophiactidae) as an epibiont on loggerhead sea turtle, Caretta caretta
FIGURE 1. Heavily encrusted female loggerhead sea turtle (plastic tags of Yakushima Umigame-kan, No. Y8390 on the right hind flipper and No. Y8389 on the left hind flipper). The first landing record of this turtle was 2002 July, 21th in Yakushima Is. Landings of this turtle were recorded in 2002, 2008 and 2017.
