Anatomy A way to identify a fish is by their body structure, they have fins and a backbone. The anatomical adaptation of fins helps them survive and makes them and marine animal unique in that they use them to maintain their position, move, steer, and stop. Most fish have scales and breathe though gills. Most fish also have a mucus layer that helps them prevent infections. With in what we consider “fish,” there are many that don’t very much look like they are earth creatures. The strangest fish
CLASSIFICATION Taxonomic words can be difficult to understand. So below are some of the words that classify whale sharks from the underwater world and their definitions. Animalia: a taxonomic kingdom that includes living and extinct animals Chordata: a taxonomic phylum that includes all the animals that have a spinal column (backbone) Chondrichthyes: a class of fish that have cartilaginous skeletons Orectolobiformes: an order of carpet sharks Rhincodontidae: a family of small-toothed sharks Rhincodon
The Swell Shark, whose scientific name is Cephaloscyllium Ventriosum, is swell. The Swell Shark has many unique features, including its habitat, anatomy, feeding, and defense tactics. The Swell Shark is also a member of many diverse taxonomic groups, including Chordata and Chondrichthyes. These groups have many defining characteristics, which the Swell Shark displays all of. Lastly, despite the Swell Shark being of Least Concern in terms of conservation, it is still important to protect this species
Evolution can be defined as a developing process, where an animal or plant gradually becomes a more advance and multifaceted form. Examples of evolution include natural selection and mutations. Throughout history our planet and the species found on it were required to evolve to survive. Thus, leaving the best possible forms to survive and thrive throughout history. This process took time and has produced many variations, but the common result is species that became enhanced. There are many different
Migration Migration is the movements or travels made by animals to locations outside of their natural environment for an extended period of time (Dingle 2007). Typically when migrating, animals are searching for a sustainable location with many of the resources needed available. Some animals migrate back and forth between the same areas while others avoid returning to the same area. A rule of thumb when discussing where animals migrate is by looking at the animal’s life span. Animals with a longer
Late Devonian Mass Extinction: Conodonts Introduction The Late Devonian mass extinction that takes place at the Frasnian-Famennian boundary is considered as one of the Big 5 mass extinctions (McGhee, 1998). Life at this time experienced huge losses among many different marine groups such as: brachiopods, molluscs, trilobites, conodonts, fish, as well as other organisms. In order to pinpoint a cause for the mass extinction both physical and geochemical processes have been looked at. The usual
