IV. New observations on life-history features. 



1 . Interesting observations were acquired for Dairella californica, which 

 turned out to be a rather common species in the subantarctic Pacific 

 Ocean. It seems that the live animals actually penetrate their substrate, 

 and bury their abdomen, reminiscent of the behavior of hippoboscid 

 flies (Vinogradov 1988) (Figure 7).
