During this time a behavior budget was developed for activity observed in Crystal Cove while sightings of dolphins by the public in Newport Harbor were catalogued. Data was collected through onsite observations by 2 or more observers at a time. A Dorsal fin ID method was also used to determine individual dolphins that may be using the area more frequently than others. A total of 38 dolphins were observed from the Research cottage at Crystal Cove where the majority of activity consisted of unidirectional

There are venom glands along 13 dorsal spines‚ three anal spines‚ and two pelvic spines that extend about three quarters of the way up from the base to the tip (Morris 2009‚ 119).

is one of the most abundant demersal shark species. This shark is gray or brownish on top and pale gray or white on its ventral side with irregular white spots on the top or sides of the body. The second dorsal fin is smaller than the first and both fins have spines at their origin. The caudal fin is asymmetrical with the upper lobe being larger.

water their whole life. Sharks swim by moving their tail and bodies side to side; instead dolphins move their tails and bodies up and down. Lastly‚ one more main difference between a dolphin and a shark is the dorsal fin; on a dolphin the dorsal fin at the top is curve‚ yet on sharks the dorsal fin is straight. While they both live in the ocean‚ these are just a few points about how sharks and dolphins are truly different ocean creatures. Title: The Difference Between Sharks and Dolphins Topic

underside is also white‚ though both sides of the fluke are black. The two white patches that make up the hourglass shape are often connected by points or at least a thin white line‚ though in some individuals the two white patches do not touch. The dorsal fin is easily notable and concave‚ though in some individuals it becomes sharply hooked backwards. Pectoral flippers may also have a definite "elbow" and curve back sharply on their leading edge. Diet & Behaviour: Stomach contents of stranded hourglass

Would you like to be kept in a small area‚ be told how to live your life and have no freedom whatsoever? Life for captive marine animals is nothing like life in the ocean. They have lost a lot in order to fulfil the entertainment we so called get from watching them perform and getting abused in the environments they are put in.
