Post-diapause development, emergence, and hatching as observed by light microscopy in live B. poppei isolated from sediment of lake on King George Island, Antarctica. (a) Early stage of development (ED Embryo). (b) Intermediate stage of development (ID Embryo). (c) Pre-nauplius. (d) Emergent pre-nauplius. (e) Outer wall (white arrow) of cyst shed. (f) Inner cyst wall (white arrowhead) shed as the hatching membrane (black arrow) expands. (g) Hatching membrane fully expanded; nauplius begins burst swimming (Supplementary Video S1). (h) Free-swimming nauplius larva.
