Ambulocetus (Latin ambulare "to walk" + cetus "whale") is a genus of early amphibious cetacean [a] from the Kuldana Formation in Pakistan, roughly 48 or 47 million years ago during the Early Eocene . It contains one species , Ambulocetus natans (Latin natans "swimming"), known solely from a near-complete skeleton.
Whales are fully aquatic, open-ocean animals: they can feed, mate, give birth, suckle and raise their young at sea. Whales range in size from the 2.6 metres (8.5 ft) and 135 kilograms (298 lb) dwarf sperm whale to the 29.9 metres (98 ft) and 190 tonnes (210 short tons) blue whale, which is the
It was designated a UNESCO World Heritage Site [2] in July 2005 [3] for its hundreds of fossils of some of the earliest forms of whale, the archaeoceti (a now extinct sub-order of whales). The site reveals evidence for the explanation of one of the greatest mysteries of the evolution of whales : the emergence of the whale as an ocean-going ...
The whale's scientific name is Eubalaena glacialis, which means "good, or true, whale of the ice". The cladogram is a tool for visualizing and comparing the evolutionary relationships between taxa. The point where a node branches off is analogous to an evolutionary branching – the diagram can be read left-to-right, much like a timeline.
When a large marine mammal like a whale dies, its body drifts to the ocean floor in a process known as whale fall. For more than a decade, a succession of sea creatures will live off of the whale ...
Thus, more recent evolution of these complex blubber traits occurred after baleen whales and toothed whales split, and only in the toothed whale lineage. [ 10 ] [ 11 ] [ 12 ] Modern toothed whales do not rely on their sense of sight, but rather on their sonar to hunt prey.
Before Halloween turned into a candy and costume-driven commercial phenomenon, its origins span centuries and diverse global evolution.
