Heavy pigment bar at midtail; by flexion stage, concentrated at midtail on dorsal and ventral margins, on lateral midline, and along myosepta; 2 dorsal fin rays 39-42; pelvic fin rays 5, decreasing to 2 by adult; through postflexion stage, anus at midbody; head length about 33% of BL and body depth about 30% of BL; pelvic fin rays not as early forming or elongate as in Physiculus. Pigmentation: Preflexion: on brain, gut, nape, and pectoral and pelvic fin bases; broad bar at midtail, near end of tail in some early stage larvae; by about 6 mm, on snout, operculum, infraorbital, and branchiostegal region; absent from posterior half of tail. Flexion: on jaw tips and isthmus; gradually expanding posteriad along tail. Postflexion-juvenile: occasionally on ends of first few 2 dorsal fin rays and ends of pelvic fin rays; line along dorsal and ventral margins and lateral midline of tail. Sequence of fin development: pectorals, pelvics, first and second dorsal and anal, caudal. |
