Not as whales, no. Marine (sea) mammals (whales, dolphins, etc.) are descended from terrestrial (land) mammals, but they're not identical with those land mammals... among the more obvious changes, they've lost their legs. The related links section has a link to a Wikipedia page showing what some of the distant ancestors of whales might have looked like.
Some whales are classified as mammals. Smaller fish are not
NO! They're mammals.
Yes, whales are the largest mammals.
Yes, pilot whales are mammals.
Yes they are. Remember that Narwhals are whales, and that whales are most certainly mammals.
Whales are mammals. Mammals are warm blooded.
Modern whales are believed to be related to ancient mammals based on several lines of evidence, including fossil records, anatomical similarities, and genetic studies. Fossils of early cetaceans, such as Pakicetus and Ambulocetus, show transitional features between land-dwelling mammals and modern whales. Additionally, molecular analyses reveal genetic links between whales and terrestrial mammals, particularly artiodactyls (even-toed ungulates), supporting their evolutionary relationship. These findings collectively illustrate the evolutionary journey of whales from land to water.
aye, whales and dolphins ARE mammals. Although, why they are I am not sure.
No. There are many aquatic mammals.
Yes, they do. Whales are marine mammals, and all mammals are vertebrates.
All whales are mammals. As are dolphins as well.
