Maternal-Fetal Trophic and Respiratory Relationships in Viviparous Ectothermic Vertebrates

17β-Estradiol Causes Abnormal Development in Embryos of the Viviparous Eelpout

“…Exposure of pregnant eelpout to ethinylestradiol causes a decrease in osmolarity and chloride concentrations, 37 and lack of ovarian fluid may influence gas exchange and cause hypoxia. 38 Hypoxia is a well-known inducer of embryonic malformations or early death. 2,39 Types and Frequencies of Malformations.…”

Allosteric Control of Oxygen Binding by Haemoglobin During Embryonic Development in the Crocodile Crocodylus Porosus: The Role of Red Cell Organic Phosphates and Carbon Dioxide

“…A similar argument may be advanced for C. porosus. Reptiles belonging to the Squamata, in contrast, do not appear to have similar ontogenetic changes in haemoglobin components, and oxygen affinity appears to be regulated allosterically (Korsgaard and Weber, 1989). The general pattern of change in blood oxygen-affinity during embryonic development is geared to the regulation of oxygen supply in response to metabolism.…”

The evolution of the placenta

“…the spiny dogfish, which at birth weighs 40% less than the yolk-filled fertilized egg from which it develops. The tiger shark, by contrast, solves such limiting provisioning by the dominant embryo eating all of its littermates and any unfertilized eggs before birth (Korsgaard and Weber 1989). …”
