Presentation Transcript

  1. Seals, Whales and Dolphins Ecology, classification and threats.

  2. What is a Marine Biologist? What do Marine Biologists do?

  3. Today! • Who we are - DONE • What is a mammal? • Classification of marine mammals • Adaptations for surviving in the ocean • Marine Mammal survey techniques • Why survey marine mammals – conservation? • Your marine conservation pledges

  4. Polar oceans Coral reef Marine habitats Rocky Shores Deep sea oceans Open oceans

  5. Defining Mammals All Mammals have the following: • Warm blooded • Give birth to live offspring • Hair • Feed their young milk • Breath air/have lungs

  6. Classifying Mysticete Baleen is used to filter the water for krill and plankton like a comb, Whales can passively filter 2000-2500kg of food per day

  7. Classifying Odontocete Jaws are used to bite into food and prey, They are useful for hunting specific prey

  8. Classifying Pinnipeds Fin footed mammals • Seals • Sea Lions • Walruses

  9. Classifying The Others! • Polar Bears • Manatees & Dugongs • Sea Otters • Humans?

  10. Classifying The Others! • Polar Bears • Manatees & Dugongs • Sea Otters • Humans?

  11. Adaptations How are Marine Mammals adapted to their environment? • Fins instead of limbs • Blowhole (whales/dolphins) • Voluntary breathers • Blubber • Large oxygen storage (hold breath longer) • Strong dive response (slow heart rate)

  12. Marine Conservation Issues • Marine Pollution • Over fishing • Endangered species • Climate change • Noise pollution In groups – think of how WE can help

  13. Preventing Threats Possible ways to prevent threats are: • Proper disposal of waste • Bins & Toilet! • Eating wide variety of fish • Reduce overfishing • Reduce carbon emissions (eg. walk & cycle) • Use eco-products in our home

  14. What can I see in the North East of England?

  15. Pledge Think of a promise you can make to help reduce the threats towards Marine Mammals YOU can make it happen in 2014!
