Whales, the ocean’s largest marine mammals, renowned for their immense size and exceptional adaptability can be found roaming waters all over the world. ... Whale Watch: A 5-Day Unit Plan for ...
Whale skulls have small eye orbits, long snouts (with the exception of monodontids and ziphiids) and eyes placed on the sides of its head. Whales range in size from the 2.6-metre (8.5 ft) and 135-kilogram (298 lb) dwarf sperm whale to the 34-metre (112 ft) and 190-metric-ton (210-short-ton) blue whale.
The timeline of the evolutionary history of life represents the current scientific theory outlining the major events during the development of life on planet Earth. Dates in this article are consensus estimates based on scientific evidence , mainly fossils .
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.
The whale’s decomposing body is located at what is called the Clayoquot Slope Bullseye site, where Ocean Networks Canada (ONC) scientists monitor methane gas escaping the seafloor. In 2012 and ...
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 name Whippomorpha is a combination of English (wh[ale] + hippo[potamus]) and Greek (μορφή, morphē = form). [2]Some attempts have been made to rename the suborder Cetancodonta, due to the misleading utilization of the suffix -morpha for a crown group, [6] as well as the risk of confusion with the clade Hippomorpha (which consists of equid perissodactyls); [7] however Whippomorpha ...
