The bottlenose dolphin is a species of dolphin and part of the kingdom animalia, they are vertebrates because they have dorsal spines, are multicellular and depend on respiration for energy. They belong to the phylum Chordata because they have a backbone, they belong to the class Mamalia, which includes all mammals. Dolphins are mammals because at some point in their lives they grew hair, nurse their young with milk, can regulate their body temperature (warm-blooded), breathe air, and give live births. They are in the order Cetacea, which is where whales, dolphins and porpoises are found; their suborder is Odontoceti which indicates that dolphins have teeth. Bottlenose dolphins are classified in the Delphinidae family made up of all oceanic dolphins; their subfamily is Delphinae, members of this subfamily are medium-sized oceanic dolphins that have a rostrum or beak. The genus is where all the bottlenose dolphin species are placed, which is Tursiops, there are several species and subspecies of bottlenose dolphins: common bottlenose dolphin, Indo-Pacific bottlenose dolphin and lagoon dolphin. The species of bottlenose dolphin is Truncatus and the full scientific name of the bottlenose dolphin is Tursiops Truncatus. Say no to plagiarism.

A bilateral symmetry is found in organisms that may have a line drawn to divide the organism into two mirror-image halves. Yes, tissues are present in dolphins. Their skeletal elements are supported by connective tissue and cartilaginous pads. The dorsal fin serves for balance. Flukes are flattened pads of hard, dense, fibrous connective tissue, completely devoid of bone or muscle. Each tail lobe is called a fluke. The dorsal fin is built like the pectoral fins, dense fibrous connective tissue, without bones. There are three germ layers in dolphins, animals with three germ layers are called triploblastic. The first germinal layer is the ectoderm, which is the outermost layer, covering the surface of the embryo, giving rise to the external covering and, in some phyla, the central nervous system. The endoderm, the innermost germinal layer, lines the sac that forms during gastrulation and gives rise to the lining of the digestive tract or cavity, as well as the liver and lungs of vertebrates. A third germ layer, the mesoderm, lies between the endoderm and ectoderm, the mesoderm develops into the muscles and most other organs between the digestive tract and the outer covering of dolphins. Bottlenose dolphins have a thoracic cavity (or thoracic cavity) which is the vertebrate body chamber protected by the thoracic wall (rib cage and associated skin, muscles and fascia). The central compartment of the thoracic cavity is the mediastinum. Vertebrates, which include dolphins, have the dorsal body cavity, it is a fluid-filled space surrounding the brain and spinal cord, the dorsal cavity is usually regarded as two semi-separate spaces, the cranial cavity and the spinal cavity, Housing the brain and spinal cord, the thoracic cavity (or thoracic cavity) is the chamber of the vertebrate body protected by the thoracic wall (rib cage and associated skin, muscles, and fascia). The central compartment of the thoracic cavity is the mediastinum. The pelvic cavity is a body cavity delimited by the bones of the pelvis. Its oblique roof is the pelvic inlet (the upper opening of the pelvis). Its lower limit is the pelvic floor. The pelvic cavity mainly contains the reproductive organs, the urinary bladder, the pelvic colon, and the rectum. The abdominal cavity contains a series,.
