giraffe : a large fleet African ruminant mammal that is the tallest of living quadrupeds and has a very long neck and a short coat with dark blotches separated by pale lines — Webster
Giraffe is a genus of African even-toed ungulate mammals, the tallest living terrestrial animals and the largest ruminants. The genus currently consists of one species, Giraffa camelopardalis, the type species. Seven other species are extinct, prehistoric species known from fossils. Taxonomic classifications of one to eight extant giraffe species have been described, based upon research into the mitochondrial and nuclear DNA, as well as morphological measurements of Giraffa, but the IUCN currently recognizes only one species with nine subspecies.
The giraffe’s chief distinguishing characteristics are its extremely long neck and legs, its horn-like ossicones, and its distinctive coat patterns. It is classified under the family Giraffidae, along with its closest extant relative, the okapi. Its scattered range extends from Chad in the north to South Africa in the south, and from Niger in the west to Somalia in the east. Giraffes usually inhabit savannahs and woodlands. Their food source is leaves, fruits and flowers of woody plants, primarily acacia species, which they browse at heights most other herbivores cannot reach. Giraffes may be preyed on by lions, leopards, spotted hyenas and African wild dogs. Giraffes live in herds of related females and their offspring, or bachelor herds of unrelated adult males, but are gregarious and may gather in large aggregations.
The giraffe has intrigued various cultures, both ancient and modern, for its peculiar appearance, and has often been featured in paintings, books, and cartoons. It is classified by the International Union for Conservation of Nature as Vulnerable to extinction, and has been extirpated from many parts of its former range. Giraffes are still found in numerous national parks and game reserves but estimations as of 2016 indicate that there are approximately 97,500 members of Giraffa in the wild, with around 1,144 in captivity. — Wikipedia

With funding from Cabot Institute for the Environment, BZS and the EPSRC's CASCADE grant, a joint team flew to Cameroon in December to trial the use of drones, sensor technologies and deployment techniques to monitor populations of the Critically Endangered Kordofan giraffe at Bénoué National Park.

Ancient Greeks imagined that everything in the natural world came from their goddess Physis; her name is the source of the word physics. Present-day nuclear physicists at the Department of Energy's Oak Ridge National Laboratory have created a GODDESS of their own—a detector providing insight into astrophysical nuclear reactions that produce the elements heavier than hydrogen (this lightest of elements was created right after the Big Bang).

Despite being four times thicker than human hair, elephant hair is only half as strong—that's just one finding from researchers studying the hair strength of many different mammals. Their work, appearing in a paper publishing December 11 in the journal Matter, shows that thin hair tends to be stronger than thick hair because of the way that it breaks.
Optical switch illuminates cell development

Combining light and a protein linked to cancer, researchers at Princeton University have created a biological switch to conduct an unprecedented exploration of cellular development in the embryo.

Herbivorous dinosaurs evolved many times during the 180 million-year Mesozoic era, and while they didn't all evolve to chew, swallow, and digest their food in the same way, a few specific strategies appeared time and time again. An investigation of the skulls of 160 non-avian dinosaurs revealed the evolution of common traits in the skulls and teeth of plant-eating members of otherwise very different families of these extinct reptiles. These new examples of convergent evolution in plant-eating […]
