Course modules
Data collection (23 minutes)
The most important aspect of identifying a marine mammal on the beach is recording where, when, and what you saw. Learn how to collect useful, accurate scientific data from a carcass and where to report any dead marine mammals that you find.
Otariids, or eared seals (39 minutes)
Meet the eared seals. Learn how to identify sea lions and fur seals when found on the beach.
Phocids, or true seals (13 minutes)
Harbor seals and northern elephant seals, also known as the “true seals,” are commonly found on San Francisco Bay Area beaches. Learn how to distinguish them from the eared seals.
Mustelids, or otters (9 minutes)
In this section, we discuss the natural history, biology, and unique features of Mustelids, the weasel family. The two most common mustelid species found in the San Francisco Bay Area are the southern sea otter and the North American river otter.
Mysticetes, or baleen whales (18 minutes)
There are approximately 90 species of whales, dolphins, and porpoises throughout the world. In this module, we focus on the baleen whales, which forage using a filtering system consisting of baleen plates inside their mouths to catch prey.

Odontocetes, or toothed whales (31 minutes)
In this unit, we focus on the odontocetes, or the toothed whales. This group includes dolphins, porpoises, and all other whales possessing teeth, such as the beaked whales and sperm whales.
