: Below is an excerpt from an article that provided information about dolphins. There are 20 blanks in the text that need to be COVERED AND filled with prepositions. Use the correct/appropriate prepositions in context to fill the blanks. Description Dolphins are small-toothed Cetaceans, a group of marine mammals that evolved land mammals. They have developed numerous adaptations that make them well suited for life in water including a streamlined body, flippers, blowholes and a layer blubber for insulation. Dolphins have curved beaks which means they appear to have permanent smiles. Dolphins evolved from land mammals whose legs were underneath their bodies. As a result, dolphins tails move up and down as they swim, whereas a fish’s tail moves side to side. Dolphins, like all toothed whales, lack olfactory lobes and nerves. Because dolphins do not possess these anatomical features, they most likely have a poorly developed sense smell. The snout of some oceanic dolphins is long and slender due to their elongated, prominent jaw bones. Within the dolphins' elongated jaw bone sits numerous conical teeth (some species have as many as 130 teeth in each jaw). Species that have prominent beaks include, for example, Common Dolphin, Bottlenose Dolphin, Atlantic Humpbacked Dolphin, Tucuxi, Long-Snouted Spinner Dolphin, and numerous others. The forelimbs of a dolphin are anatomically equivalent the forelimbs of other mammals (for example, they are analogous to arms in humans). But the bones the forelimbs of dolphins have been shortened and made more rigid supporting connective tissue. Pectoral flippers enable dolphins steer and modulate their speed. The dorsal fin of a dolphin (located on the back of the dolphin) acts as a keel when the animal swims, giving the animal directional control and stability within the water. But not all dolphins have a dorsal fin. For example, the Northern Rightwhale Dolphins and the Southern Right whale Dolphins lack dorsalfins.

Dolphins do not have prominent external ear openings. Their ear openings are small slits (located behind their eyes) which do not connect to the middle ear. Instead, scientists suggest that sound is conducted the inner and middle ear by fat-lobes located by the lower jaw and various bones the skull. Habitat and Distribution Many dolphins inhabit coastal areas or areas shallower water. While most dolphins prefer warmer tropical or temperate waters one species, the orca (sometimes called killer whale) lives both the Arctic Ocean and the Antarctic Southern Ocean. Five dolphin species prefer fresh to salt water; these species inhabit rivers South America and South Asia. Diet and Behavior Dolphins are carnivorous predators. They use their strong teeth hold their prey, but then eitherswallow their prey whole tear it small pieces. They are relatively light eaters; the bottlenose dolphin, for example, eats about 5 percent of its weight each day. Many species of dolphins migrate find food. They consume a wide range of animals includingfish, squid, crustaceans, shrimp, and octopus. The very large Orca dolphin may also eat marine mammals such as seals or marine birds such as penguins. Many dolphin species work as a group herd or coral fish. They may also follow fishing vessels enjoy the "waste" thrown overboard. Some species will also use their flukes beat and stun their prey.
