Gray whales, incidentally, are sometimes known as Californian or Pacific gray whales, and their scientific name is Eschrichtius robustus. They are a type of baleen whale, which means that they feed by swimming through the sea and filtering out their prey, such as various crustaceans, from the water. The baleen is the filter-like adaptation in a gray whale’s mouth through which it sucks in water.
These magnificent dark gray creatures can weigh up to 40 tons and grow up to 49 feet in length, with a typical lifespan of between 55 and 70 years. Gray whales also lack dorsal fins and instead have backs that are humped and ridged. Plus, they generally feed in shallow waters near the shore.
