Darwin discussed about some anomalous forms in fresh water basins, which belong to the remnants of some interesting orders. Because these anomalous forms exhibit the anomaly of geographical distribution e.g. Ganoid fishes, or morphological anomaly such as Ornithorhynchus and Lepidosiren , they may be called living fossils. It is believed that Darwin presented the facts of the above anomalous forms, and used the term "living fossil" in order to further illustrate the subject of "Circumstances Favorable for the Production of New Forms Through Natural Selection" in Chapter IV. The term "living fossil" appears on page 486 again in the last Chapter, i.e. Chapter XIV "Recapitulation and Conclusion", where Darwin emphasized the significance of so-called "living fossils".

Physiological Responses of Hybrid Striped Bass to Aqueous Copper copper is an abundant trace metal, and although essential at low levels, it is also potentially toxic to aquatic organisms.Mechanisms of toxicity and consequences of exposure vary depending on ionoregulatory status(acclimated to freshwater or salt water).The goal of this research was to examine the responses of hybrid striped bass(Morone chrysopsXMorone saxatilis)exposed to Cu in freshwater and 15g/L salt water.In freshwater,a general dose-and time-dependent pattern of increasing Cu accumulation in gill tissue was evident in fish exposed to aqueous Cu(220 and 447 mg/L)for up to 96 hours.The 96-horu acute median lethal concentration for freshwater-acclimated hybrid striped bass exposed to Cu was 94mg/L(confidence interval=62 to 144mg/L).
