Taxonomic comments. Liao and Clark (1995) distinguished between Calliderma spectabilis Fisher 1906 View in CoL and C. emma Gray 1847 View in CoL on the basis of presence/absence of sharp spines on the radial abactinal plate regions (spines present on C. spectabilis View in CoL ). Liao and Clark (1995) argued that differences between the two species were slight and that the radial abactinal spines in C. emma View in CoL were artefactually absent, thus removing the most significance difference between the two species. Examination of C. emma View in CoL / C. spectabilis View in CoL specimens, further supports their hypothesis that the two species are synonyms. Liao and Clark’s (1995) synonymy is adopted herein.
In situ observations. Although not observed feeding, Calliderma View in CoL occurs widely and is a subject of some fossil study (e.g., Villier et al. 2004) and as such, its living in situ life mode is considered herein. Calliderma emma View in CoL [called C. spectabilis View in CoL by Fisher (1906), see taxonomic note] is observed in many HURL images of the Hawaiian deep-sea benthos. All of the images observed show individuals on fine to coarse grained sediment in a diversity of current regimes (e.g., Fig. 4 View FIGURE 4 A). None were observed on hard bottoms. Rays of this species were always splayed out on the bottoms with the arm tips upturned into the water. Only individual animals were observed in images reviewed with no other C. emma View in CoL individuals present within the field of view. One image (M-211-036) showed C. emma View in CoL in relatively close proximity (within 2 feet / 1 meter) distance to multiple aspidodiadematid echinoids but no interaction was evident ( Fig. 4 View FIGURE 4 A).
Occurrence. Hawaiian Islands, China, (near Hainan Island), Gulf of Carpentaria, northern Australia. 138– 387 m.
