Cyberlab Observing Marine Mammal Behavior: 3. Based on your observations, what are some scientific questions that you could ask about the animals behavior? 4. Answer the question below: a. Why is it important to conduct field studies in addition to satellite tracking? b. Why would studying fish in the field be different from marine mammals?

Marine Mammals Explain: Read The Marine Mammals (pgs. 408-412). Answer question #3 (pg. 412) the table below: Cetaceans Pinnipeds
Marine Mammals The Marine Mammals: What are the characteristics all mammals share? Give birth to live young. Babies develop inside the mother. Have hair; either full (Polar Bear) or just a few on the chin (Dolphin). Marine Mammals Endothermic or warm-blooded. Maintain body temperature separate from the environment. Nurse young. Mothers produce milk.
Marine Mammals The Marine Mammals: Marine mammals have been classified into a few major groups: Cetaceans Sirenians Sea Otters Pinnipeds Polar Bear
Marine Mammals Cetaceans. Blowhole: special hole on the top of cetacean head through which they breathe. Cetaceans have sleek, bulletshaped bodies, & a strong tail. Fluke: tail area that moves up & down to propel the animal through the water. Rostrum: long mouth area
Marine Mammals Cetaceans. These marine mammals must breathe voluntarily - unlike humans who breathe without thinking about it. -diving Deep cetaceans often remain near the surface for several minutes to catch their breath before heading back down. Whales exhale a cloud like blow, which is a mixture of, air including carbon dioxide & unused, oxygen, liquid water spray &. mucus
Marine Mammals Cetaceans: Do not have much hair, but have layers of fat under their skin called, blubber which helps regulate body temperatures.
Marine Mammals Cetaceans: There are two major groups of cetaceans. Toothed whales Baleen whales
Marine Mammals Cetaceans. Toothed whales: Most eat fish or squid & use their teeth to tear apart their prey. Many toothed whales use sound to, echolocate, navigate & communicate.
Marine Mammals Cetaceans. Baleen whales: Includes species that have broom-like plates in their mouths that strain food out of the water. Their diet includes smaller prey such as krill & small schooling fish & squid.
Marine Mammals Cetaceans. NOAA describes 11 species of baleen whales & 67 species of toothed whales. Most cetaceans are marine mammals; however, there are some which live in freshwater habitats considered to be aquatic mammals. Cetacean behavior varies widely by species. They communicate using, clicks, whistles &, groans which can be heard over very long distances.

Marine Mammals Pinnipeds. Must go on land to give birth & to. nurse young They are much more agile in the water because they have front & hind. flippers What are the three main groups of pinnipeds? Eared seals True seals Walruses
Marine Mammals Pinnipeds. Eared Seals: Have an earflap on the outside of their bodies. They use their longer flippers to walk on land by twisting their back limbs forward.
Marine Mammals Pinnipeds. True Seals: Move on land by flopping around on their. bellies Walruses: Have long tusks used to dig up shellfish from the seafloor, break through ice, haul themselves onto. ice flows
Marine Mammals The Marine Mammals. Discussion: Pinnipeds spend a lot of time on land. Why are they considered to be marine mammals?
Marine Mammals The Marine Mammals. 3. Compare & contrast the cetaceans & pinnipeds. Cetaceans Pinnipeds blowholes for breathing mammals have hair breathe air nurse young ocean dwelling variety habitats spend much of their time on land mate on land give birth on land
Marine Mammals Sirenians. Include manatees &. dugongs Manatees live on both sides of the. Atlantic ocean Dugongs are found in the. Indio-Pacific
Marine Mammals Sirenians. These animal are sometimes referred to as. sea cows Sirenians are plump with flattened tails. Their diet consists of, plants making them vegetarians or. herbivores Spend most of their time in water like cetaceans & have stif bristles around the mouth like. walruses
Marine Mammals Polar Bears. What are some interesting facts about Polar Bears?
Marine Mammals Sea Otters. What are some interesting facts about Sea Otters?
Marine Mammals Explain: Read Observing Marine Mammals in the Field (pgs. 412-413). Highlight or underline key information.
