First spine small, more or less hidden in the skin, second spine about two thirds of third, following spine sub equal, the last half snout, and as long as first ray. Dorsal rays increasing in length to about the 20th, which is as long as snout, the posterior rays rapidly decreasing in length, the fin hence pointed behind. Origin of anal below last dorsal spine. the first spine hidden in the skin, the second about three fourths of the third, which is longest, and as long as longest dorsal spines. Soft anal similar to soft dorsal. Pectorals equal to head, ventrals much pointed, longer than pectorals. Caudal lunate, the lobes much pointed and produced. Gill rakers 14-16 anterior row, 13-15 posterior row. Minute scales. Philippine specimens demonstrate different color patterns. Dorsal spines (total): 9 - 9; Dorsal soft rays (total): 27 - 30; Anal spines: 3; Anal soft rays: 25 - 28. The venomous caudal spine can cause painful wounds.
