A variety of research activities on the organisms in the Ross
Dependency was undertaken to determine the biological research
potential of the organisms. Most work focused on photoreceptors
of different invertebrates and fishes. The studies included work
on: a) Glyptonotus antarcticus: The dorsal and ventral eyes of
this big isopod were prefixed, postfixed, dehydrated and
embedded for ... transmission electron microscopy (TEM).
Additional eyes were prepared for TEM of the inner and outer
surfaces. Groups of 4 animals were adapted to 0°C, 5°C and 10°C
and their eyes were also prepared for TEM. Another experiment
involved painted one eye black and exposing the other to 200 lux
for 1 week. Both eyes were analysed with TEM. b) Orchomenella
plebs: Freshly caught amphipods were exposed to bright sunlight
for 1, 2 and 3 hours. Their eyes, as well as those of fully dark
adapted ones were prepared for TEM. This species can also
recover when placed in 10°C for 7h and then returned to 0°C
water. Eyes of animals adapted t
