Classification
Domain-Eukarya
-Cells have organelles that are bound by a membrane.
Kingdom-Animalia
-multi-cellular,
they develop from an embryo, and they depend on other organisms
for their energy (Schoolworkhelper,
2013).
Phylum-Chordata
-Has
a spinal cord.
Class-Elasmobranchii
-Comprised
of sharks and rays, whose skeltons are mainly cartilaginous (The
free dictionary, 2013).
Order-Carcharhiniformes
-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
- Dorsal fin lacks spines (The
free dictionary, 2013).
Genus-Galeocerdo
-
Translates to tiger shark
(The
free dictionary, 2013).
Species-
Galeocerdo cuvier
-
Means a large voracious shark of tropical wates, has vertical
stripes, and has a brown to grey color to it (The
free dictionary, 2013).
*Classifications from
(Enchanted
learning, 2010)
This
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.
This
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).
