Biology

provided by Fishbase
Adults prefer exposed reefs and deeper pools. Also found in rock pools (Ref. 9003). Eggs are hemispherical and covered with numerous sticky threads that anchor them in the algae on the nesting sites (Ref. 240). Larvae are planktonic which occur primarily in shallow, nearshore waters (Ref. 94114). B. dorsalis is the largest known triplefin species and the only fish predator in the family (Ref. 13227).
