“…Hedgpeth, 1969;map 5), die als Ektoparasiten h~ufig mit Seeanemonen assoziiert sind, stiitzen diese Annahme. Nach Monteiro & Tommasi (1983a) kommen dort auch Ophiuriden vor, die sonst antarktisch verbreitet sind. Das Eindringen einer tiefseeischen demersalen Rochen-Art in dieses Becken (Hart, 1946;Fig.…”

“…Mature specimens were present in Clade I in February (Antarctica), April (South Georgia, Antarctica), and November (South Georgia); Clade V had mature specimens in April and November (Supplementary Material 3). Only 2% of the total specimens were observed to carry young in the bursae, much fewer than expected (following Monteiro and Tommasi (1983), the expectation was closer to 11%) ( Table 2). Brooding was only recorded from five specimens from South Georgia/ Shag Rocks (4% of total individuals in this region, Table 2).…”

“…For each individual we described the presence of gonads, as well as any direct evidence of brooding, such as the presence of juveniles inside the bursae. In order to compare brooding and sexual maturity at different locations, we used the definition of Monteiro and Tommasi (1983) as sexually mature "individuals incubating juveniles or harboring ovaries with distinguishable eggs" and extracted some reproductive data from Monteiro and Tommasi (1983). In ten specimens from different locations/clades, we also measured the size of the largest eggs from the ovaries using a binocular microscope.…”
