Answer:
The mechanisms used to produce sound vary from one family of cetaceans to another. Marine mammals, such as whales, dolphins, and porpoises, are much more dependent on sound for communication and sensation than are land mammals, because other senses are of limited effectiveness in water. Sight is less effective for marine mammals because of the particulate way in which the ocean scatters light. Smell is also limited, as molecules diffuse more slowly in water than in air, which makes smelling less effective. However, the speed of sound is roughly four times greater in water than in the atmosphere at sea level. As sea mammals are so dependent on hearing to communicate and feed, environmentalists and cetologists are concerned that they are being harmed by the increased ambient noise in the world's oceans caused by ships, sonar and marine seismic surveys.[2]

This is an essay about the character, Charley Le Grant.
Charley Le Grant is an ambitious and cunning deputy, who one day, decides to earn a bit of extra money by performing a task that would as well satisfy his thirst for adventure. He discusses the idea of collecting and selling oysters on the narrator after taking a glance of a boat full of them running ashore. He later witnessed the discussion between a constable and a pirate crew, arguing over the possession of the oyster trove. Charley learns of the constable, Mr. Taft's plight and notifies the narrator, "I'm going to interview him about that reward". He volunteers himself and his crew on the quest of retrieving the oysters from the pirates.
Having successfully made a deal, Charley and the narrator use their wits on a plan's design to execute their task. They hire a third member, Nicholas, who aids them in providing knowledge of the pirate island. Having designed the plan, Charley drops his two companions on the island, promising to return later to extract them along with the goods.
After a while, Charley returns to the island and picks up his companions along with a couple of sacks full of oysters. They rowed back home, nimbly dodging gunshots, but manage to fulfill their task triumphantly.
