Description
Summary:Phorbas megasigma Ríos & Cristobo, 2007 (Fig. 9, Tab. 6) Phorbas megasigma Ríos & Cristobo, 2007a: 1486 –1488, figs. 1–5, tab. 1. Material. Several fragments of 1 (?) specimen from station 048-1 (SMF 11817, 11833), 602.1 m, 70° 23.94' S, 8° 19.14' W, 12.01.2008. Description. Sponge grows upright reticular, composed of 2 to 5 mm thick fibres, rarely forming wider, flattened structures (Fig. 9 A). Fibres regularly intercrossing, often in rectangular pattern. Surface bristled, knotty, porous, often with small openings (0.5 mm) piercing through entire sponge body. Consistency rather soft, spongy. Color in ethanol brownish beige. Skeleton: Made up of plumose tracts of acanthostyles, interconnected by irregularly scattered acanthostyles (Fig. 9 B). In epidermis, echinating bundles of tornotes present. Chelae regularly distributed throughout the tissue. Spiculation (Tab. 6): Main spicules acanthostyles (Fig. 9 C), 520–645 µm in length and 15–25 µm in diameter. Additionally, smaller acanthostyles occur (Fig. ... : Published as part of Göcke, Christian & Janussen, Dorte, 2013, Demospongiae of ANT XXIV / 2 (SYSTCO I) Expedition — Antarctic Eastern Weddell Sea, pp. 28-101 in Zootaxa 3692 (1) on page 57, DOI: 10.11646/zootaxa.3692.1.5, http://zenodo.org/record/249019 ...
