Notes
The resting egg of Brachionus and Asplanchna is an encysted embryo consisting of two concentrically arranged, syncytial tissue layers which are surrounded by a multilamellar shell. In Asplanchna there are major differences between the embryo of the resting egg and the parthenogenetic embryo both in shell structure and in the organization of the embryonic tissues. The possible adaptive significance of these differences is discussed in relation to dormancy.
