Each day a sperm whale eats 2,000 pounds of giant squid, octopus, and cuttlefish. This diet maintains the whale's body: 60 feet in length and weighing as much as 140,000 pounds (70 tons). The sperm whale was once hunted to near extinction. Currently the world's population of sperm whales is about 500,000; the number killed by hunters has decreased drastically during the past 40 years.
What is a depressant?
A depressant is a drug that reduces the activity of various body functions. Some depressants such as anesthetics, sedatives, antiepileptics, narcotics analgesics, and some muscle relaxants, slow nervous and muscular activity by acting on the central nervous system. Tranquilizers are depressants that affect only part of the nervous system. They induce relaxation without causing total depression.
