Bottlenose Dolphin Research Paper
Bottlenose Dolphin
• Kingdom: Animalia
• Phylum: Chordata
• Class: Mammalia
• Order: Cetacea
• Sub-order: Odontoceti
• Family: Delphinidae
• Genus: Tursiops
Species: Truncatus
Habitat
Being the most prevalent dolphin species in the world, the Common Bottlenose Dolphin is widespread, active throughout both temperate and tropical waters worldwide. Despite this extensive range, it does not appear to be present in polar waters (pole-ward 45°) except in southern New Zealand and northern Europe, typically inhabiting waters with a surface temperature between 10 and 32 degrees celsius. The Common Bottlenose Dolphin is one of few species that expoits a wide array of habitats around the world, including both temperate and tropical inshore, …show more content…
Most dolphins have pointed teeth to grasp, slippery fish which are swallowed whole. Some other dolphins has a few teeth in the lower jaw only, which helps it suck in and swallow squid.Dolphins swallow their pray whole or in large chunks. After swallowing the food travels down the esophagus to arrive at the stomach, a muscular sac where digestion starts. A dolphin has three compartments, it is more complex than that of other meat animals, such as humans, cats, and dogs. These types of animals only have one. Muscular churning in the first part of the dolphins stomach, the fore stomach grinds up the food. This process is called mechanical digestion. the resulting mush called chyme it squirted into the second chamber, the main stomach where chemical digestion begins. The walls of the main stomach secrete hydrochloric acid to reduces the pH and protein- digesting enzymes, more protein digesting enzymes to chemically break down the food. The walls of the third stomach, secrete fat-digesting enzymes. more protein digesting enzymes, and an alkaline fluid that neutralizes the acidity of the main stomach juices. The partly digestive food now enters a short tube called the duodenum, the first part of the small intestine. The pancreatic duct and the bile duct empty their contents into this organ. Pancreatic juices contains a mixture of digestive enzymes for …show more content…
From the esophagus the food travels to the Fore Stomach where it can be stored or regurgitated at will, it then passes to a spherical stomach where digestive juices and acids are released, then on to the Pyloric stomach and finally through the Pyloric sphincter where Pancreatic and Bile ducts empty their digestive enzymes and juices. From this point we empty into the Intestines which run only the length of the Dolphin terminating at the anal opening from where waste is excreted. This shortened intestinal tract is found in animals with the ability to digest their food source in short time due to their exceptionally strong enzymes and digestive juices. Normally this type of animal is an active carnivore with a rather high metabolic
