-Cells have organelles that are bound by a membrane.
    -multi-cellular, they develop from an embryo, and they depend on other organisms for their energy (Schoolworkhelper, 2013).

    -Comprised of sharks and rays, whose skeltons are mainly cartilaginous (The free dictionary, 2013).
    -Separates the sharks from the rays by the need to have two dorsal fins along with an anal fin, five gill slits,nictitating eyelids, and no nasoral groove (Fish base, 2013).
Family- Carcharinidae

*Classifications from (Enchanted learning, 2010)

phylogenetic treeThis phylogenetic tree the morphology of organisms that are seperated in to 6 clades (Carlson, 1999). As you can see sharks evolved early and have been around for a very long time.

phylogeny 2This phylogenetic tree shows how the morphology of teeth found in the clade Galea are related. The tiger shark is a carchariniform and as you can see, its teeth are highly evolved. Its closest relative tooth wise are the Lamniformes, which include sharks such as the bullhead shark (Randell, 2012).
