Distribution

A similar brownish-orange undescribed Beroe species has been observed in Antarctica, in the Ross Sea ( Brueggeman 1998) (Fig. 11 d) and in the Weddell Sea (photographed by ©Ingo Arndt, https://www.mindenpictures.com/search?s=Ingo+Arndt+beroe). Another pink-orange Beroe was collected and photographed off Argentina, but the specimen was too damaged to properly identify (see Figure 2F in Schiariti et al. 2021).

Notes

Description of and comments on observed material (Fig. 11): N = 3 in 2018 and N = 4 in 2019. Body shape long and oval (body length ca. 2.4 times body width), eight comb rows above the meridional canals, starting close to the aboral end, of equal length ca. 2/3 of the body length [ca. 85 comb plates per row in Little Razorback Island LRISH2010_Beroe_sp_A_g specimen], meridional canals extend past the oral end of the comb rows, space between comb plates short (space between four comb plates ca. equal to length of comb plate); white and brownish-orange divertula without anastomoses; orange-brown stomodeum, its length nearly full body length. None of the currently described Beroe species found in the Southern Ocean matched with the description of our specimens (Table 1 ). Although colour supposedly is of little taxonomic significance to distinguish between Beroe species (e.g. Arai 1988, Quoy and Gaimard 1824), it is the first time that brownish-orange specimens have been formally described for this genus in the Southern Ocean (Table 1 ). Observed swimming or immobile at any depths between the seafloor and the surface ice cover, orientated either horizontally or vertically (with aboral end pointing up or down).
