How is a Ambulocetus related to a whale?
A Walking Whale: Ambulocetus
Like hippos, their closest living relatives, whales are descended from an ancestor that had four legs and walked on land, a transition explored in the upcoming exhibition Whales: Giants of the Deep, opening March 23.
What did Ambulocetus look like?
Compared to other early whales, like Indohyus and Pakicetus, Ambulocetus looks like it lived a more aquatic lifestyle. Its legs are shorter, and its hands and feet are enlarged like paddles. Its tail is longer and more muscular, too.
What is a Ambulocetus habitat?
Ambulocetus was found in an area which was a shallow sea off the shores of a coastal swamp or forest, and it may have predominantly inhabited brackish areas such as at a river mouth.
What features did the Ambulocetus have?
Ambulocetus had a long and flexible neck, front limbs with flexible wrists and fingers, powerful legs with large feet, and a long and robust tail that likely lacked tail flukes. ... Most paleontologists think that Ambulocetus could have walked on land, although it was probably slow and awkward.
When was the Ambulocetus found?
Reconstruction of the fossil whale Ambulocetus from the Eocene of Pakistan (~ 49 million years ago). Ambulocetus was discovered in 1994. In this artists reconstruction, Ambulocetus is shown living like a crocodile, hunting land mammals near the shore.
Did whales used to walk?
Although whales are expert swimmers and perfectly adapted to life underwater, these marine mammals once walked on four legs. Their land-dwelling ancestors lived about 50 million years ago.
What adaptations did the Ambulocetus have?
(Ambulocetus literally means "walking whale") They share their ear structure with whales, which would have enabled them to hear under water by picking up vibrations. They also had an adaptation in their nose that allowed them to swallow underwater and their teeth are similar to dolphins and whales.
How old is Rodhocetus?
Age: 46-47 million years ago, Eocene Epoch.
Can Ambulocetus hear well underwater?
Like modern whales Ambulocetus was well-adapted to hearing underwater and may well have lost the ability to hear on land altogether. Other whale-like features include its nose, which was adapted so that it could swallow underwater, and its teeth.
Is Ambulocetus a transitional fossil?
Ambulocetus is a very important transitional fossil as it displays the link between terrestrial mammals and the early whales. Ambulocetus acquired its name from the idea that it could both swim by undulating its back as well as leave the water and walk on land.
Did the Ambulocetus swim?
Ambulocetus ("walking whale") was an early amphibious cetacean. It could walk as well as swim.
Who discovered Ambulocetus?

What were whales before they evolved?
Both hippos and whales evolved from four-legged, even-toed, hoofed (ungulate) ancestors that lived on land about 50 million years ago. Modern-day ungulates include hippopotamus, giraffe, deer, pig and cow.
Are cetaceans carnivores?
All cetaceans are carnivores and do not consume plants or algae as food. The large baleen whales eat schooling organisms that range in length from minute drifting mollusks, copepods (1 cm or less), krill (1–5 cm), and small fish and squid up to about 40 cm.
