Here we document the early gamogenetic development of Cyclestherida, including a characterization of the nervous system. Resting eggs in Cyclestheria are protected by an ephippium, built by the major part of the carapace. The first stages of development are enclosed in an outer chorion and an inner vitelline membrane. After shedding of the chorion, the vitelline membrane inflates and later stages are free‐floating within the vitelline membrane. Only the juveniles are released from the vitelline… Expand
The Development of Arthropod Segmentation Across the Embryonic/Post-embryonic Divide – An Evolutionary Perspective
In many arthropods, the appearance of new segments and their differentiation are not completed by the end of embryogenesis but continue, in different form and degree, well after hatching, in someExpand
Transitions in functional morphology from “large branchiopods” to Cladocera: Video and confocal microscopic studies of Cyclestheria hislopi (Cyclestherida) and Sida crystallina (Cladocera: Ctenopoda)
TLDR
The functionality and morphology of the swimming antennae and feeding appendages in clam shrimps and cladocerans are studied and the findings are analyzed in an evolutionary context (e.g., possible progenetic origin of Cladocera). Expand

Study of the late embryogenesis of Daphnia (Anomopoda, ‘Cladocera’, Branchiopoda) and a comparison of development in Anomopoda and Ctenopoda
TLDR
The embryonic development of Daphnia galeata and D. hyalina has been investigated by observing living embryos removed from female brood pouches and the sequence of morphological changes was analysed, as was the time at which the activity of certain organs began. Expand
Unraveling the origin of Cladocera by identifying heterochrony in the developmental sequences of Branchiopoda
IntroductionOne of the most interesting riddles within crustaceans is the origin of Cladocera (water fleas). Cladocerans are morphologically diverse and in terms of size and body segmentation differExpand
Nervous system development in Spinicaudata and Cyclestherida (Crustacea, Branchiopoda)—comparing two different modes of indirect development by using an event pairing approach
TLDR
The first indications of the evolutionary transformation which the Cladocera may have undergone from a clam shrimp‐like ancestor are given. Expand

TLDR
A comparison between Cyclestheria and the Upper Cambrian ‘Orsten’ fossil Rehbachiella kinnekullensis reveals a remarkable similarity in the endite morphology of the trunk limbs. Expand
Comparative investigation of the late embryogenesis of Leptodora kindtii (Focke, 1844) (Crustacea: Branchiopoda), with notes on types of embryonic development and larvae in Cladocera
TLDR
A new scheme for the periodization of the embryogenesis of L. kindtii is proposed, which includes four well‐separated stages, which is similar in all these groups but the timing of shedding of the embryonic membranes differs. Expand
Reproductive Biology of Marine Cladocerans
TLDR
The chapter summarizes the life cycle of a podonid cladoceran, using Evadne nordmanni as an example and physiology and nutrition of marinecladocerans is discussed. Expand
Development and staging of the water flea Daphnia magna (Straus, 1820; Cladocera, Daphniidae) based on morphological landmarks
TLDR
A staging system for Daphnia magna, which is based on morphological landmarks, which can be adopted for other daphnids with minor variations since the sequence of development is highly conserved during early stages and only minor heterochronic shifts occur in late embryonic stages. Expand
EMBRYONIC CUTICLES OF ARTEMIA DURING DIAPAUSE AND HATCHING: INSIGHTS FROM COMPARISON WITH OTHER BRANCHIOPODA
TLDR
Observations on anostracans in the family Chirocephalidae, unlike Artemiidae, molt only one embryonic membrane, and that the outer cuticular membrane in Artemia is part of the first embryonic cuticle indicates that the hatching membrane inArtemia also results from a second embryonic ecdysis. Expand
Review of Colombian Conchostraca (Crustacea) — ecological aspects and life cycles — family Cyclestheriidae
This study gives an overview and describes special aspects of the biology, ecology and the life cycle ofCyclestheria hislopi (Baird, 1859). This species is most commonly found in parthenogenicallyExpand
Comparative analysis of the late embryogenesis of Sida crystallina (O.F. Müller, 1776) and Diaphanosoma brachyurum (Lievin, 1848) (Crustacea: Brachiopoda: Ctenopoda)
TLDR
Differences in the duration of embryogenesis in Sida and Diaphanosoma are explained by greater extension of the first, and especially the fourth, instars of Sida, while theduration of the second and third instars are approximately the same in both. Expand
