living in two environments (water and land)
academicscienceanimal-general
1. amphibious; living both in water and on land
A compound element meaning "living in two environments," built from 両(りょう) (both) + 生(せい) (life, living). It almost never stands alone, appearing instead inside compounds such as 両生類(りょうせいるい) (amphibians).
Amphibians can live in both water and on land.
両生(りょうせい)類(るい)は幼生期(ようせいき)にえら呼吸(こきゅう)をする。
Amphibians breathe through gills during their larval stage.
「両生(りょうせい)」という言葉(ことば)は「両生(りょうせい)類(るい)」以外(いがい)ではあまり使(つか)われない。
The word "ryōsei" is rarely used outside the compound "amphibian" (ryōseirui).

両生(りょうせい) literally means "living both ways," describing an organism that lives in water and on land. It is a bound compound element, not a free-standing word.

Compounds

  • 両生(りょうせい)類(るい): amphibians (frogs, toads, newts, salamanders)
  • 両生(りょうせい)的(てき): amphibious (figurative, of things or people that operate in two different domains)

Watch out

Used alone, 両生(りょうせい) sounds incomplete to native speakers; it is almost always attached to 類(るい) or 的(てき).
