SulfolobalesSulfolobales is an order of archaeans in the class Thermoprotei. PhylogenyThe currently accepted taxonomy is based on the List of Prokaryotic names with Standing in Nomenclature (LPSN) and National Center for Biotechnology Information (NCBI).
Cat behaviorCat behavior encompasses the actions and reactions displayed by a cat in response to various stimuli and events. Cat behavior includes body language, elimination habits, aggression, play, communication, hunting, grooming, urine marking, and face rubbing. It varies among individuals, colonies, and breeds. Communication and sociability can vary greatly among individual cats.
NematomorphaNematomorpha (sometimes called Gordiacea, and commonly known as horsehair worms, hairsnakes, or Gordian worms) are a phylum of parasitoid animals similar to yet distinct from nematode worms in morphology, hence the name. Most species range in size from 5 to 10 centimetres (2 to 4 in), reaching 2 metres (6 ft 7 in) in extreme cases, and 1 to 3 millimetres (0.039 to 0.118 in) in diameter.
GC-contentIn molecular biology and genetics, GC-content (or G+C content or guanine-cytosine content) is the percentage of nitrogenous bases in a DNA or RNA molecule that are either guanine (G) or cytosine (C). This measure indicates the proportion of G and C bases out of an implied four total bases, also including adenine and thymine in DNA and adenine and uracil in RNA. GC-content may be given for a certain fragment of DNA or RNA or for an entire genome.
CatSmall domesticated carnivorous mammalThe cat (Felis catus), also called domestic cat and house cat, is a small domesticated carnivorous mammal. It is a member of Felidae, the family of mammals in the orderCarnivora also colloquially referred to as cats. An obligate carnivore requiring a predominantly meat-based diet, it has retractable claws adapted to killing small prey species such as mice and rats.
ExtinctionTermination of a species' lineageThe thylacine (Thylacinus cynocephalus) is an example of a recently extinct species.Palaeotherium is an example of an extinct genus that is only recorded from fossil records before the existence of hominids.Extinction is the termination of a species via the death of its last member. A taxon may become functionally extinct before the death of its last member if it loses the capacity to reproduce and recover.
FloraFlora (pl.: floras or florae) is all the plant life present in a particular region or time, generally the naturally occurring (indigenous) native plants. The corresponding term for animals is fauna, and for fungi, it is funga. Sometimes bacteria and fungi are also referred to as flora as in the terms gut flora or skin flora for purposes of specificity.
LifeMatter with biological processesLife is the capacity in matter, formed of one or more units called cells, for processes such as cell signalling, homeostasis, metabolism, cell growth, adaptation, response to stimuli, and reproduction. All life eventually reaches a state of death. Many philosophical definitions of living systems have been proposed, such as self-organising systems.FaunaFauna (pl.: faunae or faunas) is all the animal life present in a particular region or time. The corresponding terms for plants and fungi are flora and funga, respectively. Flora, fauna, funga and other forms of life are collectively referred to as biota. Zoologists and paleontologists use fauna to refer to a typical collection of animals found in a specific time or place, e.g. the "Sonoran Desert fauna" or the "Burgess Shale fauna".Outline (list)An outline, also called a hierarchical outline, is a list arranged to show hierarchical relationships and is a type of tree structure. An outline is used to present the main points (in sentences) or topics (terms) of a given subject. Each item in an outline may be divided into additional sub-items.

FlatwormPhylum of soft-bodied invertebratesPlatyhelminthes (from Ancient Greek πλατύ (platy) 'flat' and ἕλμινς (helmins) 'parasitic worm') is a phylum of relatively simple bilaterian, unsegmented, soft-bodied invertebrates commonly called flatworms or flat worms.
