The animal or rather mammal that I choose to report on is the Bottlenose Dolphin. Bottlenose Dolphins are from the Kingdom: Animalia, Phylum: Chodata, Class: Mammalia, Order: Cetacea, Suborder: Odontoceti, Family: Delphinidae, Genus: Tursiops and Species: truncatus. This partiuclar species of dolphin are generally light to dark grey throughtout their dorsal surface, fading into a white coloration along the ventral region of their bodies. Their general body shape is considered a streamlined fusiform. Their namesake comes from a rather pronounced anterior rostrum (“beak”) that is typically 3 inches long. Their rostrum typically contains anywhere between 75-100 concially-shaped homogenous teeth. It should be noted that their are two main disctinct …show more content…
As seen in most species in the animal kingdom, the Bottlenose Dolphin has bilateral symmetry that can be divided into two equal and identical mirror images. Dolphins, in general, have a very similar anatomy to that of humans, therefore, they have tissues present. These tissues form and function normally, meaning the same as we do; dolphins have atoms, cells, tissues, organs, and organ systems. As such, this represents their level of organization. Likewise, they are triplobastic in nature meaning that they have three germinal layers. Additioanlly, dolphins are coelomate, therefore having a body cavity which is lined by the mesoderm known as coelomates. During gastrulation, the blostopore forms the rectum, it belongs to …show more content…

As a species dolphins are extremely social creatures and spend will their time together on a number of different activities including hunting for food. By hunting as a group these marine mammals maximize their ability to successfully capture their prey while avoiding being injured or attacked. During hunting expeditions dolphins can often be seen traveling together in pods consisting of 2 – 30 dolphins using a number of sophisticated strategies and group oriented hunting techniques to stun, isolate and capture their prey. One technique dolphins are known to use (known as a bait ball) to capture fish involves a group of dolphins swimming around a pool of fish in a circle, which forces the fish to form into a tightly knit ball. Once the fish are gathered together and unable to escape the dolphins
