Presentation transcript:

Am I monogamous or polygamous? Class Mammalia Order Pinnipedia Elephant seals are polygamous. One male breeds with many females and defends harems of females from other males.

Harbor seal

California sea lion

Class? Order? Common name? Mammalia Carnivora Sea otter

Class? Order? Common name? Mammalia Carnivora Polar bear Why am I in danger of going extinct? Polar bears use sea ice as a platform for catching seals. They wait by the seal’s breathing holes in the ice for a seal to come up for air. Arctic sea ice is declining due to global warming and polar bears are having a hard time gaining enough weight in the summer to survive hibernation in the winter.

Order Sirenia Manatee Herbivore Am I a herbivore or a carnivore?

Class? Order? Common name? Mammalia Pinnipedia Walrus No, I am only found in the northern hemisphere. I am found in the arctic. Can you find me in the Antarctic?

This is a baleen whale (Order Cetacea – Suborder Mysticeti) Baleen whales have a blowhole with two openings

What is this? The baleen of a baleen whale What suborder is this whale in? Mysticeti

Mammalia Class? Order? Suborder? Common name? Cetacea Odontoceti Sperm whale

Identify 1 – 6 in the diagram below 1. Trachea 4. Muscle cells which have an oxygen carrying pigment called myoglobin inside them 2. Lungs 5. The red blood cells (hemoglobin) is passing its oxygen to myoglobin 3. Red blood cells with oxygenated hemoglobin 6. Oxygenated myoglobin

1. Air enters the mouth and nose 5. Primary bronchi or bronchiole tree 2. Pharynx 6. Alveoli 3. Esophagus (transport food to the stomach) 7. Larynx 4. Trachea (windpipe)

What kind of whale is in this diagram? Humpback Whale This whale is feeding by a process called? Bubble netting

Common name? Order? Suborder? Gray whale Cetacea Mysticeti How does this whale feed? Gray whales are baleen whales, thus they are filter feeders. This whale is grabbing a mouthful of sediment from the sea floor and will use its baleen to filter out amphipods that are buried in the sediment

Class? Order? Suborder? Common name? Mammalia Cetacea Odontoceti Dolphin
