  From  Webster's  Revised  Unabridged  Dictionary  (1913)  [web1913]: 
 
  Statoblast  \Stat"o*blast\,  n.  [Gr.  ?  standing  (i.  e.,  remaining) 
  +  -blast.]  (Zo["o]l.) 
  One  of  a  peculiar  kind  of  internal  buds,  or  germs,  produced 
  in  the  interior  of  certain  Bryozoa  and  sponges,  especially  in 
  the  fresh-water  species;  --  also  called  {winter  buds}. 
 
  Note:  They  are  protected  by  a  firm  covering,  and  are  usually 
  destined  to  perpetuate  the  species  during  the  winter 
  season.  They  burst  open  and  develop  in  the  spring.  In 
  some  fresh-water  sponges  they  serve  to  preserve  the 
  species  during  the  dry  season.  See  Illust.  under 
  {Phylactol[ae]mata}.
