Mottled stripes are found along the sides of younger sharks, fading as the shark ages. Countershading provides tiger sharks with a bit of camouflage to take prey by surprise, with a darker color on the dorsal surface (back) and a lighter color on the ventral surface (belly). If you were to view the shark from below, the light underside would blend in with the lit ocean surface, and if you viewed it from above, it would blend in with the darker ocean floor. A huge wedge of a snout holds the serrated teeth that have a distinct notch (see picture below). Other characteristic features include five gill slits, and an elongated top lobe on the caudal (tail) fin.
Later, funding was sought and given to a team from the Hawaii Institute of Marine Biology to test the idea of site-attachment. Sharks were captured, tagged, measured, and implanted with a tracking device so that swimming and travel behavior could be monitored. This research indicated that the tiger sharks roamed between the islands and were not bound to one given territory. Therefore, culling would not produce the desired effect. Research continues to be conducted to gain insights about these amazing creatures. To learn more, visit: http://www.hawaii.edu/HIMB/ReefPredator/Tiger%20Shark%20Research.htm
