Study Notes
Marine Mammals Overview
- Odontocetes are toothed whales with large body size, 2 blowholes, symmetrical skull, and solid jaw bones.
- Mysticetes, another type of whale, have a variable number of teeth, feed on fish and squid, and exhibit strong sexual dimorphism.
- Pinnipeds are amphibious mammals that haul out on land/ice to birth and nurse, and include true seals and sea lions.
- Otariids, a type of pinniped, have external ear pinna and hindlimbs that can rotate forward, with males 2-6 times larger than females.
- Odobenids, such as the walrus, have no external ear pinnae and hindlimbs that can rotate forward.
- Mustelids like the sea otter and marine otter give birth, nurse, mate, molt, and forage in the water.
- Ursids, such as the polar bear, spend most of their life on top of ice and prey on other marine mammals.
- Sirenians, including the dugong and manatees, are herbivorous marine mammals with heavy bones and thin blubber.
- Marine mammals of the Northwest Atlantic include the minke whale, orca, beluga, and various dolphin species, each with distinct physical characteristics.
- Specific features like blow shape, dorsal fin shape, body length and shape, and color pattern are used to identify different marine mammal species.
- The text includes detailed descriptions of various whale species, such as the blue whale, fin whale, humpback whale, sperm whale, and orca.
- Characteristics like dorsal fin shape, blow shape, and color patterns are used to differentiate between different whale species.
