  1. Cuvier’s Beaked Whaleby Laurie McBride

  2. Overview • Classification • Habitat • Physical characteristics • Behavior • Sonar definition and effects • Evidence

  3. Classification • Order: Cetacea • Family: Ziphiidae • Scientific name: Ziphius cavirostris • Common names: • Cuvier’s Beaked Whale • Goose-beaked Whale • Goosebeak Whale

  4. Habitat • Atlantic Ocean • Pacific Ocean • Indian Ocean • Prefer deep water • Large number of strandings determines distribution

  5. Mass: 3000 kg Length: up to 7 m Small, blunt head Single pair of teeth, males only Physical Characteristics

  6. Physical Characteristics • Flipper pockets • Varied coloration • Scar coverage • Swirling patterns

  7. Behavior • Deep divers • Found in small pods • Feed on squid, fish, crustaceans • No specific breeding season • Stranded more than other beaked whales • Why?

  8. Man-made echolocation LFAS Use of sonar Fishing Military Harmful to marine life? What is Sonar?

  9. What are the Effects? • Navigation • Breeding • Communication • Behavior • Inner ear damage • Leads to strandings

  10. Bahamas strandings Canary Islands strandings Necropsies Both events coincided with sonar exercises What is the Evidence?

  11. In Conclusion • Classification of Cuvier’s Beaked whale • Found in deep waters of several oceans • Unique physical characteristics • Behavior includes deep diving • Sonar definition and effects • Evidence includes strandings
