Transcript of Dolphin Digestion

The digestion of a dolphin Anna Sophia Kuppel So, what is a dolphin??? A dolphin is a mammal living in the water. They are very social animals and do almost everything in a group. There are many different types of dolphins. Instead of breathing through a nose, they breath through a blowhole at the top of their heads. Also they have something called a melon close to their brain to help them see since they are practically blind. What do dolphins eat? Dolphins eat a variety of different animals and plants just like humans. Their digestive system can handle many things humans can. Unless of course bread which is unhealthy for almost any animal. They also eat small fish, plankton, crabs, shrimp and other small animals. Ocasionally when they find one they can easily kill, they eat a squid. How do dolphins obtain their food? Dolphins hunt in two different ways. The first way is called herding. This is when a group of dolphins surround what they would like to eat. This has to be easy to defeat, such as a school of fish, or a small squid. Then they all get closer and closer to their victim until it has no more ways to escape. Then they all take turns to feed off of the quid or school of fish while the others keep the remaining fish trapped. The second way that dolphins hunt catch their food is called corralling. This happens when dolphins chase their prey as close to the shore as possible. Then the prey is stuck in-between the shore and the dolphin(s). Bibliography "EVOLUTION."

To eat, dolphins usually use one of two techniques, one is called herding and the other corralling. Both are explained well detailed in the how do dolphins obtain their food slide. With any of these ways of capturing food, dolphins wait for their turn to feed and when they go they eat quickly, if they were taking turns to feed on a school of fish, a dolphin would go and swallow a fish without even chewing. If the fish is too big for the dolphin to swallow it will hold the fish by its tail, (tail inside the mouth) and hit it against surrounding stones or if is shallow enough, against the ocean floor. How do dolphins digest their food? Dolphins, although having sharp teeth try to avoid chewing. This means food will go directly down to the esophagus. The dolphin has three stomachs, the fore stomach, the spherical stomach and the pyloric stomach. First food travel through the fore stomach. The fore stomach is also a storage area for food. After the fore stomach, food continues towards the spherical stomach. In the spherical stomach is where all the acids are released, also digestive juices are released. The pyloric stomach is the last stomach food goes through. After the pyloric stomach comes the pyloric sphincter where bile empties its enzymes and juices. After the pyloric sphincter comes first the small intestine and then the large intestine. In the small intestine nutrients are taken from foods. In the large intestine liquids are taken from the food. After the large intestine, comes the rectum where the leftover waste is made into feces. After feces is created in the rectum, feces exits the dolphin's body through the anus. Conclusion In conclusion, dolphins are very cool animals that live a fun an healthy life style. They live in habitats full of animals they can eat, and stay away form predators. They also live in groups, just like humans live in families. Also, they have a similar digestive system, in some parts at least.
