Study Notes
Marine Mammals Families
- Pinnipeds family includes sea lions, fur seals, and walruses.
- Sirenians family consists of dugongs and manatees.
Seals and Distinctions
- True seals (Family Phocidae) lack external ear flaps and have a streamlined body shape, making them adept swimmers.
Whales and Feeding Mechanisms
- Baleen whales possess baleen plates instead of teeth, allowing them to filter zooplankton and phytoplankton from the water.
- Toothed whales use teeth to catch and consume prey like fish, octopus, and squid.
Characteristics of Marine Mammals
- One key characteristic of marine mammals is their adaptation to living in aquatic environments.
Insulation Differences
- Marine mammals typically have a thicker layer of blubber compared to land mammals, providing them with essential insulation against cold water.
Diving Adaptations
- Specialized adaptations, such as increased lung capacity and myoglobin-rich blood, enable marine mammals to stay underwater for extended periods.
- They manage oxygen use during deep dives by slowing their heart rate and redirecting blood flow to vital organs.
Blood Volume Functionality
- Many marine mammals have a larger volume of blood, which aids in oxygen storage and enhances their endurance during dives.
