Language Arts 7 Sharks vs. Dolphins Did you know that there are several differences between dolphins and sharks.? Dolphins are air breathing mammals while sharks are a species of fish, and are not mammals. Sharks breathe in the very little air that is in water. They do have a few similarities as well. They are similar in that they both hunt for food and they both swim. I would like to share some facts about how they are alike and different. Sharks have triangular teeth with jagged edges. They can open their mouth very wide when getting ready to bite their prey. Sharks have ears on the sides of their head. They have two nostrils on the snout. Sharks use gills to take in oxygen to breathe. A shark has rough skin to protect it from injury. They have large crescent shaped tails and a pair of pectoral and pelvic fins. Sharks hunt in the evening time. They eat fish, squids, plankton, and other things like tires, whatever they can fit into their mouth usually. Sharks have well developed senses and good at hearing deep low pitched sounds. They have good eyesight. They usually …show more content…

Dolphins have dorsal fin, pectoral fins, flippers, and a powerful tail. The flippers help them move to start, stop, and turn. They have a pointed snout, and teeth are pointed. The top fin is curved or hooked. They have a long triangular body. Male dolphins are square headed. Females have rounded heads. They have soft smooth skin. They have great eyesight but have difficulty seeing the fish on the ocean floor. They use echolocation to find fish on the ocean floor. They eat a variety of fishes and invertebrates. Dolphins are smart, playful, and gentle. They can live up to 25 to 35 years old in the wild. Dolphins live in small groups called pods. They talk to each other by squeaks, and squeals, and whistles. They work together to catch their prey. The dolphins body temperature is always 97 degrees

Hourglass Dolphins inhabit different regions of the Antarctic and Subantarctic waters, which have different temperatures. Dolphins can usually be differentiated into two groups, one group prefers to stay in shallow coastal waters, while the other inhabits deeper and colder waters away from shore (N. Dellabianca 2012). According to my hypothesis, this would mean that these two groups will differ in the amount of blubber they have as the temperatures of those two environments are different. The most noninvasive way to measure the amount of blubber is to use ultrasound (M. Moore 2001). By using a long pole, an ultrasound probe can be put on the dolphins back.

Hammerhead sharks are carnivore because they eat meat much as fish species. They will eat fish to regain their energy because they use most of it swimming. They also use energy by using their sense of smell that allows them to detect blood. When a shark reaches a point when they can’t use any more energy, they will go deep into the ocean and stay there. Their preys won’t spot them as easily when they are deep in the ocean.

The bottlenose dolphin has made adaptions for its need for energy, need to reproduce, predation, and abiotic environmental factors. There are three adaptations for abiotic environmental factors. The first one is that the bottlenose dolphin will rapidly emerge from the water to dive back in as a way to save energy so they can swim faster. They also just do this for pure fun. It is common for dolphins to have a limited amount of motion but because the bottlenose dolphin only has two out of seven neck vertebrae fused, it provides them more flexibility at the neck.

They are found at a depth of 1500 meters inhabiting the Pacific Ocean. The frilled sharks can grow up to a size of 5 feet, and have sharp teeth remarkably in 25 different rows! This strange large mouth is entirely different from that of the other members of a shark family. Frilled sharks have the ability to bend their body when about to catch their prey. Many researchers insist that look like a snake at the time of predation.

The Great White Shark The Great White Sharks, known mostly because of their white underbellies, are one of the most powerful aquatic animals in the world. They can swim at about 25 Miles Per Hour (40 Kilometers per hour) because of their strong muscles and forceful tails. In addition to that, male Great Whites can grow around 11.5 to 13.1 feet long, while females can grow from 14.8 to 16.4 feet long. This paper will demonstrate how Great White Sharks are an important part of their ecosystem, how their diets work and will adequately describe their habitats. As predators in their ecosystem, Great White sharks help maintain the coral reefs and seagrass habitats.
