The caudal fin has nine dorsal and eight ventral main fin rays.
Systematics
Bleheratherina pierucciae is systematically isolated and is assigned to its own subfamily (Bleheratherininae) , since it can not be assigned to any other Indo-Pacific spearfish genus or subfamily due to its osteological characteristics, especially the mouth.
