Encyclopedia of Fish Physiology, Second Edition is a comprehensive, introductory-level reference work that aims to unite readers in the wonders of this discipline. Chapters highlight where physiological systems and processes are conserved across vertebrate groups, which supports the use of fish as a vertebrate model for investigating fundamental problems in physiology and knowledge transfer to the medical field. Other chapters highlight unique specializations and adaptations that allow fish to survive in challenging environments, leading to a deeper appreciation of the natural world. Final sections demonstrate the consequences of perturbing physiological systems and how this knowledge can empower conservation strategies to protect fish. Much has changed in the field of fish physiology since publication of the previous, Prose award winning, edition. For example, we understand better the impacts of global climate change on the physiological systems of fish, and we have gained a deeper mechanistic understanding of physiological processes through technological advancements such as gene editing with CRISPR, whole genome sequencing, and quantitative 'omic` approaches. The new edition greatly expands the closing thematic section focused on applying fish physiology to real world challenges with topics including ocean acidification, declining habitat quality due to human activities, and the use of zebrafish in biomedical studies on tissue regeneration, neurological disorders and cancer.

The true story of a deeply murderous intent that lurked menacingly beneath the waves during world war two. The torpedoes strike explosively and nine thousand people die - five thousand of them are just defenceless children. Another ship founders after being attacked by a brutal submarine commander and the ship's crew and passengers are used in a murderous kind of blood-sport. Merchant seamen are savagely machine-gunned in the water, callously slaughtered with hand-grenades or simply left to the circling sharks. Inside monsters & marine mysteries you will find:Research on mysterious land cryptids like sasquatch as well as deep-sea lifeMore about sharks - is megalodon alive or is something even nastier out there?Compelling images backed by scientific evidenceInterviews with eyewitnesses and much moreIf you're avoiding fiends that swim with fins, the wagon trail is where you'll fit in! Scaly beasts from the deep try to find a home among the tumbleweeds and desert ranches of the old west. Intense sunshine, sneaky bandits, and angry farmers make it difficult for the monsters to feel welcome, but the locals soon accept the lonesome creatures and throw a shindig in their honor. Whimsical rhymes over thirty full-color illustrations explain why there are no sea monsters in the wild west!

Part 3 of this book series puts the invertebrates of the North Sea, from molluscs to diverse cnidarians, in the context of the changing living conditions in this small part of the one big ocean. The book presents a balance between long established species and immigrants from the subtropics. Aspects of fishing, ecology and aquarium keeping were also included in this work. In addition, the preservation of cephalopods was also addressed. It would be very welcome, if in the future more people would concern themselves with the care and preservation of the wondrous and multifarious inhabitants of the North Sea. For unfortunately, many of the species shown here seem to be largely unknown to a wider public, which is why they hardly seem to have a real lobby in practice. So, we should better get to know our endemic species, before they become extinct.

This volume summarizes the results of a ten-year survey of small-sized marine Achnanthales (Bacillariophyceae) in Central Polynesia (South Pacific), focusing on their valve ultrastructures using the Scanning Electron Microscope (SEM). The degree of colonization of benthic marine substrates, species richness and emergence of new diatom taxa appear to vary according to the geologic past, presence of coral reefs and degree of insularity of each Central Polynesia island. Several recently published taxa from French Polynesia, such as Cocconeis santandrea and Xenococconeis opunohusiensis, are presented herein, together with some unpublished observations and new illustrations on all of the 13 described taxa. A Venn diagram permits the first comparison with assemblages studied with the same methodologies from Central Polynesia, New Caledonia and Mascarenes (Indian Ocean). Potential endemism is briefly discussed. The taxonomy used in this volume is based on valve ultrastructure as seen in the SEM, which allows an easier comparison of the small marine tropical Achnanthales taxa, which can be difficult to distinguish by light microscopy. It questions the presence of forms or 'morphs' in several species complexes. The concept of endemism in marine eukaryotes, currently still controversial, opens up other perspectives on the biogeography of these organisms. Marine benthic and small-sized diatoms are poorly studied in contrast to freshwater diatoms, which are often used to develop diatom indices for determining water quality. This volume can help researchers working on the taxonomy of the order Achnanthales, but will also aid students beginning detailed studies of marine benthic diatoms.

"In this entertaining and informative book, science writer Till Hein shares the most tantalizing findings from the world of seahorses, opening up some of the secrets of these magical creatures of the sea. He reveals their intriguing biological features, such as their unique prehensile tails, their fins, and their lack of a stomach (seahorses only have intestines!). He speaks to experts about the fossil record of prehistoric seahorses, and examines their unique hunting strategy involving suction through their tubular (and toothless) snout. But the most unique aspect of the seahorses is their reproductive cycle, as it is the male of the species who becomes pregnant. Seahorses have become icons in feminist and transgender male communities for the way they can reshape human cultural notions of masculinity and fatherhood. Endlessly fascinating and charmingly approachable, The Curious World of Seahorses will captivate any reader looking to learn more about one of the most incredible creatures on Earth"--
