Fig. 2. Representative digital images of the hyaloid vessels on the vitrad surface
of the retina of two species of channichthyid fishes (Hb). (A)
Chaenocephalus aceratus; (B) Champsocephalus gunnari. The
cornea, iris, lens and vitreous body were removed to allow viewing of the
hyaloid vasculature. The arteries arise from 45 main branches and form
an extensive series of parallel anastomosing channels. Blood vessels were
filled with yellow MicrofilTM. Scale bars, 3 mm.
