Eudendrium scotti Puce et al., 2002: 370, fig. 3C, D, fig. 4, fig. 5A, B; Peña Cantero, 2008: 452; 2009: 1745; Peña Cantero & Vervoort, 2009: 84; Peña Cantero et al., 2013: 736–737, fig. 3f.

Material examined. Stn 21, colony with several monosiphonic stems, a few mm high, with a few polyps (NIWA 117479); Stn 148, a few solitary polyps on Staurotheca nonscripta (MNCN 2.03/530).

Description. Polyps 300–450 µm high, with ca. 16 tentacles, and a relatively large basal groove. Cnidome composed of large macrobasic euryteles (21–24.8 x 8–10 µm), apparently only on hypostome, and small microbasic euryteles (7–8.5 x 3.5–4 µm).

Ecology and distribution. Shelf species found at depths between 10 (Puce et al. 2002) and 135 m (Peña Cantero & Vervoort 2009); present material between 168 and 397 m, epibiotic on Staurotheca nonscripta. Species found epilithic on pebbles (Peña Cantero 2009) and epibiotic on algae (Peña Cantero et al. 2013), hydroids and bryozoans (cf. Peña Cantero 2008; Peña Cantero & Vervoort 2009; Peña Cantero et al. 2013). Basibiont for other hydroids (Peña Cantero & Vervoort 2009). Gonophores in December (Peña Cantero et al. 2013).

Circum-Antarctic distribution (Peña Cantero 2009), known from Tethys Bay in the Ross Sea (Puce et al. 2002; Peña Cantero et al. 2013) and the Balleny Islands (Peña Cantero 2009), in East Antarctica, and off Livingston Island (Peña Cantero 2008), Bransfield Strait and off Low Island (Peña Cantero & Vervoort 2009), in West Antarctica. Present material collected off Possession Islands and Moubray Bay.
