Modern videography provides an ever-widening window into subsea echinoderm life with vast potential for new knowledge. Supported by video evidence throughout, this Element begins with time-lapse video made in 1983 on film, using an off-the-shelf camera, flash, and underwater housings. Although quality has now been significantly improved by digital imagery, films from over thirty years ago captured crinoid feeding behavior previously unknown and demonstrated a great potential to learn about many other aspects of their biology. This sequence is followed by several examples of recent digital videography from submersibles of deep-sea crinoids and remotely operated vehicles (ROVs) (stalked and unstalked), as well as close-up video of crinoids in aquaria. These recent studies enabled a new classification of crinoid arm postures, provided detailed views of food particle capture, and revealed a wide range of behaviors in taxa never before seen in life.

The extraxial-axial theory (EAT) and universal elemental homology (UEH) are often portrayed as mutually exclusive hypotheses of homology within pentaradiate Echinodermata. EAT describes homology upon the echinoderm bauplan, interpreted through early post-metamorphic growth and growth zones, dividing it into axial regions generally associated with elements of the ambulacral system and extraxial regions that are not. UEH describes the detailed construction of the axial skeleton, dividing it into homologous plates and plate series based on symmetry, early growth, and function. These hypotheses are not in conflict; the latter is rooted in refinement of the former. Some interpretive differences arise because many of the morphologies described from eleutherozoan development are difficult to reconcile with Paleozoic forms. Conversely, many elements described for Paleozoic taxa by UEH, such as the peristomial border plates, are absent in eleutherozoans. This Element recommends these two hypotheses be used together to generate a better understanding of homology across Echinodermata.

Echinoderms have evolved diverse and disparate morphologies throughout the Phanerozoic. Among them, blastozoans, an extinct group of echinoderms that were an important component of Paleozoic marine ecosystems, are primarily subdivided into groups based on the morphology of respiratory structures. However, systematic and phylogenetic research from the past few decades have shown that respiratory structures in blastozoans are not group-defining and they have re-evolved throughout echinoderm evolution. This Element provides a review of the research involving blastozoan respiratory structures, along with research concerning the morphology, paleoecology, and ontogeny of each of the major groupings of blastozoans as it relates to their corresponding respiratory structures. Areas of future research in these groups are also highlighted.

The echinoderms are an ideal group to understand evolution from a holistic, interdisciplinary framework. The genetic regulatory networks underpinning development in echinoderms are some of the best known for any model group. Additionally, the echinoderms have an excellent fossil record, elucidating in in detail the evolutionary changes underpinning morphological evolution. In this Element, the echinoderms are discussed as a model group for molecular palaeobiological studies, integrating what is known of their development, genomes, and fossil record. Together, these insights shed light on the molecular and morphological evolution underpinning the vast biodiversity of echinoderms, and the animal kingdom more generally.

Erratum: Table 11.1 on page 241 has been mis-set. The entries for the phyla Annelida, Bryozoa, Cnidaria, Echiura, Mollusca, Placozoa, Porifera and Rotifera should all be moved one column to the right. The deep sea environment is the most extensive on our planet. Its denizens are normally unseen but whenever they are exposed to view they are regarded as bizarre aliens from a different world. The Biology of the Deep Ocean takes a close look at this apparently hostile world and explains how its inhabitants are exquisitely adapted to survive and flourish within it.

Wildlife watching tourist activities can make an important contribution to community development and conservation, especially in developing countries, but it needs to be carefully planned and managed in order to ensure its long-term sustainability and to avoid potential adverse effects on wildlife and local communities. This report, published by UNEP and the Secretariat of the Convention on the Conservation of Migratory Species of Wild Animals (CMS), considers the socio-economic and environmental benefits that can be derived from watching wildlife tourism, including case studies from Brazil, Argentina and Mexico, the United States, Australia, Indonesia and Tanzania.

The Biogeography of the Australian North West Shelf provides the first assembly of existing information of the North West Shelf in terms of geological, oceanographic and climatological history and current understanding of such issues as biodiversity, connectivity, larval dispersal and speciation in the sea that determine the distribution patterns of its invertebrate fauna. It is intended as a source of information and ideas on the biota of the shelf and its evolutionary origins and affinities and the environmental drivers of species' ecology and distribution and ecosystem function. Regulators and industry environmental managers worldwide, but especially on the resource-rich North West Shelf, are faced with having to make decisions without adequate information or understanding of conservation values or the factors that drive ecosystem processes and resilience in the face of increasing anthropogenic and natural change. This book will provide a resource of information and ideas and extensive references to issues of primary concern. It will provide a big-picture narrative, putting the marine biota into a geological, evolutionary, and regional biodiversity context.
