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.
