Fig. 2. Gill arches and developing filaments in zebrafish larvae. Corresponding
schematic drawings are shown below. (A) Phase-contrast image of the anterior
end of a 3 d.p.f. larva showing the ventrally positioned gill arches from a
lateral view. Scale bar, 100 µm. (B) Lateral view of developing gill
filaments in a 5 d.p.f. larva. Same orientation as in A. Filaments are visible
on gill arches 2, 3 and 4. In addition, red blood cells (arrowheads) were seen
moving through filament primordia. Scale bar, 25 µm. (C) Ventral view of
the left side of the gill basket of a 5 d.p.f. larva. The first three gill
arches are visible and each gave rise to several filament primordia. Pigment
of the overlying tissue partially obscures arch 3. Scale bar, 25 µm.
Stippling in the diagram below indicates the space (i.e. buccal cavity)
between gills. e, eye; f, filament; ga, gill arch; h, heart; ov, otic vesicle;
p, pigment; ys, yolk sac.
