Theria (/ ˈ θ ɪər i ə / or / ˈ θ ɛr i ə /; from Ancient Greek θηρίον (thēríon) 'wild beast') is a subclass of mammals [2] amongst the Theriiformes. Theria includes the eutherians (including the placental mammals ) and the metatherians (including the marsupials ) but excludes the egg-laying monotremes and various extinct mammals ...

2025年2月3日 · In this article, we’ll offer you a comprehensive guide to therians, explaining what they are, debunking some common misconceptions about them, and offering advice to determine if you might be a therian yourself. A therian identifies as a species of non-human animal on every level except physical.

2023年10月30日 · Theria is a subclass of mammals, including placental mammals (Eutheria) and marsupials (Metatheria). Placental mammals have a placenta, nourish their young internally, and include diverse groups like primates and rodents.

Theria is a subclass of mammals. It includes almost all living mammals: the ones that give birth to live young, and not by using a shelled egg. The Theria are divided into two groups (infraclasses): Metatheria and Eutheria. The surviving Metatheria are the marsupials, and the Eutheria are the placental mammals.

Theria. The therian mammals all share the derived character of live birth of their young. The subclass Theria is divided into two infraclasses: metatherians and eutherians. Metatherians are usually called marsupials because of the pouch, or ‘marsupium,’ that many members of the subclass possess.
