![]() Finally, in my fifth chapter I briefly review our knowledge of elasmoid scale morphology and function, and I also demonstrate the quantitative effect mucus and epidermis have on scale morphology by in vivo imaging the surface topography of seven fish species. At last, some suggestions are proposed for the design and fabrication of new bio-inspired flexible body armors. With this comparative approach, I ask if scale morphology fits models of ecologically-driven evolution, thus seeking to link scale morphology to function. #What is the purposes of scales on fish how to#The purpose of this article is to review how to make. ![]() In my fourth chapter, I quantify scale morphology across 59 damselfish (Pomacentridae) species that exhibit multiple transitions between pelagic and benthic feeding ecologies. Some creative ideas are shaped rose brooches, table cloth tongs, jewelry boxes, and bonsai trees. ![]() In my third chapter, I use μCT and histology to study scale morphology in bigeye tuna (Thunnus obesus) and I show that regions on the anterior body of bigeye tuna have large scales made of cellular bone that are filled with adipocytes. Fish scales will keep a fish fresh longer. In my second chapter, I use both gel-based profilometry and micro-computed tomography (μCT) to show that scale morphology of the bluegill (Lepomis macrochirus) is different qualitatively and quantitatively among regions of its body. The scales of a fish provide a protective barrier to the soft and fragile inner part. In my first chapter, I describe how a method called gel-based stereo-profilometry can be used to image and quantify the three-dimensional topography of biological surfaces of interest, especially scales. They make fish more aerodynamic, and help them move through water quicker. Thus, if one knows that a particular fish has scales, it is considered a kosher fish. According to the Talmud, 2 any fish that has scales also has fins. 1 In order for a fish to be kosher, it must have both of these signs. Scales provide defense against parasites. The Torah gives two signs that determine if a fish is kosher fins and scales. Protective spines are common in slow-swimming fishes and others that need to protect themselves without moving. This thesis seeks to further our knowledge of scale morphology, evolution, and function using a combination of established, modern, and novel methods to quantify scale morphology in both intra- and inter-species contexts. Why do fish have scales To protect the fish from injury, and shield it from predators. ![]() Scales occur in many forms and past research has provided a framework to categorize scale types and a foundation for describing scale morphology. Abstract Fish scales are plates of dermal bone that are embedded in the dermis and epidermis of most fish species. ![]()
