Fig. 35. Drawings of various developmental stages of Ariosoma gilberti from the eastern Pacific ranging from a leptocephalus before metamorphosis to an elver after metamorphosis. Triangles show the anterior positions of the dorsal and anal fins, which move much farther forward along with the gut (just in front of anal fin) during metamorphosis. The scale bars show 5 mm, but not all drawings are proportional in size. Modified from Raju SN. Congrid Eels of the Eastern Pacific and Key to Their Leptocephali. NOAA Technical Report NMFS 22, U.S. Department of Commerce. 1985; 1–19.
