Abstract

Blue whales can weigh up to 160 tons, and sperm whales can dive as deep as 1,000 meters.

After shifting their habitat from land to sea, these whales spent a mind-boggling amount of time rebuilding their bodies and came to live in the world's oceans.

Pachyketus," which walked on four legs, "Ambroquetus," named for the "walking whale," and the giant reptile-like "Bacillosaurus"...... bring extinct whales that no one has ever seen back to life in realistic pictures!

Witness the evolutionary journey of the whales over 50 million years.
