Many giant mammals such as woolly mammoths, woolly rhinoceroses, and cave lions inhabited the mammoth steppe during the Pleistocene.. Varying slightly by geographical location, the mammoth steppe was dominated (in biomass) primarily by giant deer, caribou, steppe bison, horses, woolly mammoth and yak, among other mammals, and was the center for the evolution of the Pleistocene “woolly” fauna.
A gas giant is a giant planet composed mainly of hydrogen and helium. [1] Jupiter and Saturn are the gas giants of the Solar System. The term "gas giant" was originally synonymous with "giant planet". However, in the 1990s, it became known that Uranus and Neptune are really a distinct class of giant planets, being composed mainly of heavier ...
Uranus is the seventh planet from the Sun. It is a gaseous cyan -coloured ice giant. Most of the planet is made of water, ammonia, and methane in a supercritical phase of matter, astronomy calls "ice" or volatiles. The planet's atmosphere has a complex layered cloud structure and has the lowest minimum temperature of 49 K (−224 °C; −371 ...
Jupiter is the fifth planet from the Sun and the largest in the Solar System.A gas giant, Jupiter's mass is more than two and a half times that of all the other planets in the Solar System combined and slightly less than one one-thousandth the mass of the Sun. Jupiter orbits the Sun at a distance of 5.20 AU (778.5 Gm) with an orbital period of 11.86 years.
Thelenota ananas, a giant sea cucumber from the Indo-Pacific tropics. Sea cucumbers are echinoderms from the class Holothuroidea ( / ˌhɒləˌθjʊəˈrɔɪdiə, ˌhoʊ -/ HOL-ə-thure-OY-dee-ə, HOHL- ). They are marine animals with a leathery skin and an elongated body containing a single, branched gonad. They are found on the sea floor ...
Deep-sea gigantism. Examination of a 9 m (30 ft) giant squid, the second largest cephalopod, that washed ashore in Norway. In zoology, deep-sea gigantism or abyssal gigantism is the tendency for species of deep-sea dwelling animals to be larger than their shallower-water relatives across a large taxonomic range.
Saturn is the sixth planet from the Sun and the second-largest in the Solar System, after Jupiter. It is a gas giant with an average radius of about nine-and-a-half times that of Earth. [26] [27] It has only one-eighth the average density of Earth, but is over 95 times more massive.
The robot gets relatively close to the gas giant planet and takes new photos with its JunoCam instrument roughly every 53 days. NASA's $1 billion Jupiter probe has taken mind-bending new photos of ...
