Evolution of organ systems in the Crustacea: Mystacocarida and Cephalocrida in retrospect

Elofsson, Rolf LU (2019) In Journal of Crustacean Biology 39(2). p.91-97
Abstract
The morphology of the internal organs of two representative species of the crustacean classes Mystacocarida, Derocheilocaris typica (Pennak & Zinn, 1943), and Cephalocarida, Hutchinsoniella macracantha (Sanders, 1955), has been studied ultrastructurally from 1990 onwards. A review of the subject offers a unique opportunity to compare and contrast the two taxa at a time when their key positions in discussions of crustacean relationships and evolution makes any new knowledge particularly valuable. The same internal organ or organ system can be constructed very differently in the two groups, but similarities also occur. Both the similarities and differences suggest functional interpretations and shed light on evolutionary pathways. The... (More)

The importance of including anatomy and functional morphology in phylogenetic discussions is emphasized. (Less)
