Mammals are Warm-Blooded Vertebrates (have a Backbone).   
They have fur or hair, feed their young on milk, and 
have a more well-developed brains than other types of animals.

Whales

We have seen Whales a few times, Grey Whales, Humpback Whales and Orcas/Killer Whales. It’s always hard to get good pictures, with the possible exception of those we saw in the Channel Islands National Park…Grey Whales breaching and feeding (Feb 2019).

Dolphins & Porpoises

One of the best “Wild Animal Sightings” we ever had, was boating with a Super Pod of Dolphins in the Channel Islands National Park, .

Seals & Sea Lions

Many of the Seals & Sea Lions we’ve seen have been on wharves/docks in seaport cities or towns, e.g. Seattle, WA; Astoria, OR; San Francisco, CA; Monterey, CA. We’ve seen many others all along the Pacific Coast, especially the Oregon Coast (having camped there, a lot.)

Manatees

We saw some Manatees when visiting the Everglades, but just underwater.

Otters

We’ve seen both sea otters and river otters, but no pictures…yet.
