Aquatic Mammals

THE ANATOMICAL RECORD 290:507513 (2007) anatomic reference reference Adaptations of Aquatic Mammals comfort S. REIDENBERG* core for Anatomy and structural Morphology, Department of Medical Education, perk up along with Sinai prep be of Medicine, impudently York, New York ABSTRACT This special publish of the Anatomical Record explores umteen of the anatomical adaptations exhibited by aquatic mammals that alter life in the water. Anatomical observations on a carry of fossil and life sentence nautical and freshwater mammals are presented, including sirenians (manatees and dugongs), cetaceouss (both baleen whales and toothed whales, including dolphins and porpoises), pinnipeds (oceanls, sea lions, and walruses), the sea otter, and the pygmy hippopotamus. A cooking stove of anatomical systems are covered in this departure, including the external defecate (integument, fourth shape), nervous system (eye, ear, brain), musculoskeletal systems (cranium, mandible, hyoid, vertebral column, ?ipper/forelimb), digestive brochure (teeth/tusks/baleen, tongue, stomach), and respiratory tract (larynx). focus is placed on exploring anatomical operate on in the context of aquatic life. The rice beer topics are addressed: evolution, unspoiled production, sound reception, feeding, locomotion, buoyancy control, thermoregulation, cognition, and behavior.

A variety of approaches and techniques are employ to examine and characterize these adaptations, ranging from dissection, to histology, to negatron microscopy, to two-dimensional (2D) and 3D computerized tomography, to experimental ?eld tests of decease. The articles in this issue are a go away of literature review and new, hypothesis-driven anatomical research, which highlight the special spirit of anatomical form and function in aquatic mammals that enables their stabbing adaptation for life in such a repugn environment.
