Fig. 6. Morphology of the gills of larval notothenioids. The gill arches of 1
d.p.h. P. antarcticum (A) and P. borchgrevinki (B) larvae
were found to completely lack even rudimentary filaments. G.
acuticeps larvae of the same age were found to possess developing gill
filaments (C; arrows). Lamellae (arrowheads) form later in development, as
illustrated by their presence in the gills of 70 d.p.h. G. acuticeps
larvae (D). c, cartilaginous gill arch. Scale bars, 100 µm.
