      "Class Cephalocarida Sanders, " published on 01 Jan by : Robert R. Hessler, Rolf Elofsson.   The book brims with humour, from the odd-couple pairing of serious, blazer-and-tie-wearing Edgar with Jarvis the silly, slippery spectacle, to the concept of an octopus trying to pass as a dog (let alone a fruit-turban-topped octopus playing piano while juggling and ballet dancing).

    As evident from the number 4A tagged to this volume, vol. 4 as originally planned had to be split into two fascicles, 4A and 4B, simply because of the numbers of pages covered by the various contributions meant for volume 4. The present volume, then, comprises the fourth part in the series The Crustacea, i.e., the revised and updated texts from the Trait de Zoologie - Crustacea. The species-poor meiofaunal Cephalocarida have played an important role in discussions of the phylogeny and evolution of Crustacea since their discovery in One reason may be that the morphology of cephalocarids includes some aspects of putatively ancient appearance, such as the simple roof-shaped head shield, the anterior three head Cited by:

Abstract. The Cephalocarida (Sanders ) is a small class of crustaceans that has had major impact on phylogenetic studies of the subphylum. Among crustaceans, its morphology has been regarded as most primitive and thus most like that of the hypothetical crustacean ancestor (Sanders , a, b, a, b; Hessler , ; Cisne , ; Hessler and Newman ; Manton Cited by: 4.

Author: Robert R. Hessler. Cephalocarida is a class inside the subphylum Crustacea that has only twelve shrimp-like benthic were discovered inand are commonly referred to as horseshoe shrimps. All cephalocaridans are in just one family: though there is no fossil record of cephalocaridans, most specialists believe them to be basal (primitive) among : Cephalocarida, Sanders, The discovery of Cephalocarida, a marine taxon of blind crustaceans, in the mid twentieth century has contributed considerably to the debate on arthropod phylogeny and evolution.

Many features of Cephalocarida, such as their thoracopod-like maxilla, their combined enditic filter feeding and swimming, and their second-order olfactory centre in the brain, have been traced back to the ground. Introduction to the Cephalocarida. The nine described species of cephalocarids are benthic (on the sea floor) marine animals.

They are found from the intertidal zone to depths of m. Cephalocarids feed on detritus (dead organic material) and are found in all kinds. The book begins at the base of the tree of life to discuss the origin of animals and early branches of the phylogenetic tree. Cephalocarida have even been suggested to represent the sister.
