FIG. 7 in Organization and Ontogeny of a Complex Lateral Line System in a Goby (Elacatinus lori), with a Consideration of Function and Ecology

FIG. 7. Superficial neuromasts and canal neuromast homologs on the head and trunk in E. lori (rostral to left in all images). (A) Radiating lines of superficial neuromasts (lines 2, 3, 4, 5, b, and d) on cheek (lateral view). (B) Superficial neuromast series (lines ot, os, and oi) form an ''F'' on operculum (lateral view); preopercular canal pores (e, c) visible. (C) Post-otic region of head (caudal to post-otic canal pore); upper pair of SNs are aligned tip-to-tip and lower group of neuromasts extending caudally from the canal pore are aligned side-by-side (interpreted as canal neuromast homologs). (D) Portion of the double line of neuromasts on mandible (in ventral view), in which the neuromasts in the upper (more lateral) line have a tip-to-tip arrangement (line e; superficial neuromasts) and those in the lower (more median) line have a side-to-side arrangement (line i; canal neuromast homologs). (E) On the trunk, a line of three superficial neuromasts at the horizontal septum arranged tip-to-tip. (F) Middle row of superficial neuromasts on caudal fin (line lc1) aligned side-to-side. Double-headed arrows indicate axis of best physiological activity of hair cells in all images. Scale bars: A–B, 200 lm; C, 100 lm; D–E, 10 lm; F, 20 lm.
