FIG. 4 in Organization and Ontogeny of a Complex Lateral Line System in a Goby (Elacatinus lori), with a Consideration of Function and Ecology

FIG. 4. Distribution of superficial neuromasts (black circles) in body and caudal series in an E. lori post-settlement juvenile (''settler''; 38 dph, 9.5 mm SL) based on fluorescent images (see also Fig. 2D–G). Superficial neuromast series (defined by Sanzo, 1911) are color-coded: blue ¼ oculoscapular, purple ¼ anterior dorsal, pink ¼ body, and brown ¼ caudal. Names for superficial neuromast lines within series follow Sanzo (1911) and Wongrat and Miller (1991). The large pectoral fin is not drawn in order to visualize all neuromasts on the trunk. See text for additional details.

FIG. 12 in Organization and Ontogeny of a Complex Lateral Line System in a Goby (Elacatinus lori), with a Consideration of Function and Ecology

FIG. 12. Neuromast morphology in species of Tigrigobius (lateral views; rostral to left). (A) T. multifasciatus (AMNH 23621)—radiating superficial lines on the cheek (3, 4, 5, b, d; see Fig. 3B). (B) Lines 5 and b (see box in A), which have a tip-to-tip arrangement. (C) T. gemmatus (AMNH 26076)— preopercular canal (PO) pores (e, c) and opercular series (lines ot, os, oi, forming the ''F'' on the operculum). (D) T. gemmatus (AMNH 26076)— superficial neuromast line on trunk just caudal to tip of pectoral fin when against body. (E) T. dilepis (AMNH 250269)—diamond-shaped superficial neuromasts in line os (ventral horizontal line in ''F'' on operculum) with ''tip-to-tip'' arrangement and hair cell orientation (double-headed arrows) perpendicular to line. (F) T. gemmatus (AMNH 26076)—first two diamond-shaped superficial neuromasts in line b (see box in B) with ''tip-to-tip'' arrangement and hair cell orientation (double-headed arrows) perpendicular to line. Scale bars: A, C, 200 lm; B, D, 100 lm; E–F, 20 lm.

FIG. 8 in Organization and Ontogeny of a Complex Lateral Line System in a Goby (Elacatinus lori), with a Consideration of Function and Ecology

FIG. 8. Neuromast arrangements within lines in E. lori and other goby species examined. (A) Canal neuromasts, aligned ''side-by-side'' with axis of best physiological sensitivity parallel to the length of the canal and line of neuromasts (black lines represent canal walls). (B) Canal neuromast homologs or caudal fin superficial neuromasts, arranged ''side-by-side'' with axis of best physiological sensitivity parallel to line of neuromasts. On the caudal fin, each neuromast line is located on the membrane between adjacent fin rays. Dashed lines represent location of canal walls (in an ancestral canal) on the head or the fin rays on the tail. (C) Superficial neuromasts aligned ''tip-to-tip'' with axis of best physiological sensitivity perpendicular to line. Gray area ¼ sensory strip. Double-headed arrow ¼ axis of best physiological sensitivity (hair cell orientation).

FIG. 11 in Organization and Ontogeny of a Complex Lateral Line System in a Goby (Elacatinus lori), with a Consideration of Function and Ecology

FIG. 11. Ontogeny of neuromast number on one side of head in E. lori larvae and post-settlement juveniles (0–44 dph and wild-caught settler) based on histological material. Black circles ¼ canal neuromasts, open circles ¼ canal neuromast homologs þ superficial neuromasts. Canal neuromast number increases to a constant (n ¼ 8), which is reached at ~6 mm SL (~15 dph), while canal neuromast homologs and superficial neuromast number increase in number with fish size (R2 ¼ 0.982).

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.
