The Sperm Whale

  1. 1. By: Quinton Campbell
  2. 3. <ul><li>The sperm whale is the largest toothed whale and lives in pods. </li></ul><ul><li>It has the largest brain out of any animal. </li></ul><ul><li>It has a single blow hole that is S-shaped and about 20 inches long. </li></ul><ul><li>It has a 4-12 inch layer of thick blubber. </li></ul><ul><li>Sperm whales produce ambergris, a dark, waxy substance (much like cholesterol) that is produced in the lower intestines, and is sometimes found containing squid beaks. It is thought to protect them from giant squid stings. </li></ul><ul><li>The skin is usually dark gray to black, but is occasionally light gray. </li></ul>
  3. 4. <ul><li>Sperm whales are found in many open oceans, both in tropical and cool waters. </li></ul><ul><li>Sperm whales live at the surface of the ocean but dive very deeply to catch the giant squid. </li></ul>
  4. 5. <ul><li>Adult males move into high latitude temperate waters during summer, leading a solitary lifestyle. </li></ul><ul><li>In winter, the bulls return to lower latitudes for mating. </li></ul><ul><li>While females remain grouped in tropical or subtropical waters. </li></ul>
  5. 6. <ul><li>The sperm whale is a Carnivore </li></ul><ul><li>The sperm whale eats mostly giant squids by diving to the bottom of the sea. </li></ul><ul><li>They also eat fish, octopus, and skate. </li></ul><ul><li>An adult sperm whale can eat up to a ton a food a day. </li></ul><ul><li>The teeth in the long, thin lower jaw are conical and huge, about 7 inches long. These teeth weigh about 2 pounds </li></ul>
  6. 7. <ul><li>Female sperm whales help one another to look after babies, going so far as to practice communal nursing. </li></ul><ul><li>Females carry their young for 14-16 month at a time. </li></ul><ul><li>Calves are about 13 feet and weigh about a ton. </li></ul><ul><li>They nurse for 2 years but could end up possibly nursing for 8 years. </li></ul>
  7. 8. <ul><li>Mating season is in spring and summer. </li></ul><ul><li>Females give birth every 3 to 5 years </li></ul><ul><li>  Young adult males will leave female-led pods and form bachelor herds until they are able to compete in mating </li></ul>
  8. 9. <ul><li>It is thought that sperm whales have the lowest reproductive rate of any animal </li></ul><ul><li>The young are fed directly through the placenta as they develop in their mother’s womb. </li></ul>
  9. 10. <ul><li>The sperm whale has the 5 basic senses; hearing, touch, sight, smell, and taste. </li></ul><ul><li>Sperm whales use echolocation to find their food especially when they are at great depths of the sea. </li></ul><ul><li>Echolocation is the biological sonar used by several animals such as bats, and cetaceans(whales, dolphins, and porpoises). </li></ul>
  10. 11. <ul><li>Sperm whales use echolocation to catch their prey in the dark ocean depths </li></ul><ul><li>Mothers also use it to keep track of their young calf when they are diving to hunt </li></ul><ul><li>A calf can’t dive very deep because it has to breathe much more frequently than the mother has to </li></ul>
  11. 12. <ul><li>Sperm whales only known predators are killer whales. </li></ul><ul><li>Where a large group of killer whales will consistently attack, and wear down a group of sperm whales until they can separate one and finish it off. </li></ul><ul><li>The sperm whales use a defensive formation where the stick their heads together in a circle with their flukes out, and use their flukes to defend. </li></ul>
  12. 13. <ul><li>The 18 th through 20 th centuries whaling for sperm whales, was at tops and in full swing. </li></ul><ul><li>Spermaceti was an oil produced in the whales that was used for lamps, candles, crayons, soaps, perfumes, and many other products. </li></ul><ul><li>The whaling error crucially hurt the population of the sperm whale, and has been prohibited in almost every country of the world. </li></ul>
  13. 14. <ul><li>They have the largest brain out of any animal ever. </li></ul><ul><li>The whale ship Essex was once attacked by a sperm whale in 1820, and was sunk, the survivors were on longboats for months, most died to starvation or disease. </li></ul><ul><li>It is the deepest sea diving mammal. </li></ul><ul><li>The famous book “Moby Dick” was inspired to be because Herman Melville (the writer of “Moby Dick”) heard the essex’s story. </li></ul>
  14. 15. <ul><li>The process I used to complete this project was Get the template for the project, open up a certain slide, then research that slide. When I finished that slide, on moved on to the next one in line. I continued this process, until I completed the slides. </li></ul><ul><li>I learned many different things about the sperm whale, that I did not know before such as them having the largest brains out of any animal ever, and them being the deepest sea diving mammals. </li></ul><ul><li>If I did this project again, I would try to manage my time more efficiently. </li></ul>
