Biology and metabolism of Glyptonotus antarcticus(Eights)(Crustacea: Isopoda) from Admiralty Bay, King George Island, Antarctica
The Glyptonotus antarcticus population of Admiralty Bay is characterised by the wider range of body sizes than that from the Signy Island region. The sex ratio is similar in both populations. Females of all development stages were captured in Admiralty Bay between March and November, which confirms...

The Glyptonotus antarcticus population of Admiralty Bay is characterised by the wider range of body sizes than that from the Signy Island region. The sex ratio is similar in both populations.
