Seals, Whales and Dolphins Ecology, classification and threats.

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

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

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

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

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

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

Classifying Pinnipeds Fin footed mammals Seals Sea Lions Walruses

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

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

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)

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

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

What can I see in the North East of England?

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