Discussion Otolith specimens of B. speronatus have already been described from Horodok (Schwarzhans & Kovalchuk, 2022). It is interesting to note that the species has thus far only been found in two of the four Medobory back-reef locations, where they are also fairly common. Te reason for this irregular distribution pattern is not yet known.
