Bottlenose+Dolphins

**Dolphins are active predators and they eat squids, fish, crustaceans, and shrimp. Bottlenose dolphins are vulnerable, Which means that they are not yet endangered species, but could become endangered. Dolphins are probably the most intelligent marine mammal. They get their names from their nose, It is shaped like a bottle. Bottlenose dolphins have a life span of 30-50 years. They weigh about 440-600 pounds and can be an average length of 10 feet. The largest dolphin can be 14 feet long! Bottlenose dolphins are ranging from dark grey at the top near the dorsal fin and lighter grey almost white near the underside. This makes them harder to see both above and below the water. Their nose isn't really on their face that is called their rostrom. Their real nose is actually on their upper back near their head, Which is called their blow hole. They use this to breath when they come up out of the water. Bottlenose dolphins usually swim at the speed of 5-11 km per hour! For short times they can reach the speeds of 21 miles per hour! every 5-8 minutes the dolphins have to swim up to the surface to take a breath. Bottlenose dolphins usually live in groups called pods that contain up to 12 members, Usually mainly their family. The group is mainly known for its friendliness and curiosity towards humans. Occasionly a dolphin has rescued passed out or injured divers by rising them up to the surface. They are preditors and mainly eat bottom dwellers when they hunt by themselves. When they hunt in their groups they find a fish or mammal and circle around it and close together for the feast. When they are hungry they usually send out a call and listen for an echo. Their loud clicking sounds send off a sound wave that hits the front of the animal. (1)  **      **Males are slightly larger than female dolphins they live for about twenty years. But sometimes males can live up to 40-45 years. The females normally live longer. That would a lot of babies if they have one or two a year! The bottlenose dolphins live in mainly warm and tropical waters. They live in these types of waters because they dont have any furr or any extra fat to keep them warm, So they have to stay in warmer waters. Bottlenose dolphins are cetaceans,which means they are in a group of all whales and dolphins. These type of dolphins are in the family of ten toothed whales. ** <span style="font-family: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif; background-color: rgb(0, 202, 255);"><span style="background-color: rgb(104, 204, 238);"> <span style="background-color: rgb(255, 255, 255); font-family: 'Lucida Sans Unicode', 'Lucida Grande', sans-serif;">** <span style="background-color: rgb(255, 255, 255);"><span style="background-color: rgb(104, 204, 238);">The main preditor of the b <span style="background-color: rgb(104, 204, 238);">ottlenose dolphin is a shark, usually bull sharks, dusky sharks, great white sharks, and tiger sharks(4). Like you can see in figure 6 (right) baby dolphins stay with their family in a group for their whole life!

It's a high pitched and kind of sounds like a small dog. They also communicate by splashing their fins and nudging noses. Their moans, groans, whistes, and grunts can make the bottlenose dolphins sound as if they are in a heavy metal band, but bottlenose dolphins make their own kind of music. Many of the sounds they make can be imitated by holding the neck of the balloon and letting out a little air faster then slower. Bottlenose dolphins are protected, which means that they are not to be killed or harmed in any way. The way that bottlenose dolphins fish is that they get in their pods and they circle and jump around the meal. The meal is usualy sardines, and when it is they round up the clump and direct them up close to the surface. If a preditor comes in and messes it up then they call in more dolphins from miles around and get them back where they want them.
 * <span style="background-color: rgb(104, 204, 238);">Bottlenose dolphins have a very poor sense of smell since their blow hole is closed when they are under the water. Some dolphins preform for people, They can be taught how to do tricks such as doing jumps in the water and letting trained professionals ride on their backs while they are swimming. The female dolphins produce one to three kids a year after a gestation period of twelve months.(2) They respond from tones from a range of 1 to 150khz. They have acute vision in and out of the water. Their eyes adapt from being in the water. The specialized anatonomy of the dolphin ear allows it to hear verry good under the water and locate sound easily.(3) Dolphins can jump out of the water being able to do this they can be trained in acts for water shows by humans. **<span style="background-color: rgb(104, 204, 238);">
