Within the context of modern art, the term was coined by the British writer Geoffrey Grigson in 1935 and subsequently used by Alfred H. Barr in the context of his 1936 exhibition Cubism and Abstract Art. Biomorphist art focuses on the power of natural life and uses organic shapes, with shapeless and vaguely spherical hints of the forms of biology. Biomorphism has connections with Surrealism and Art Nouveau.

The Tate Gallery's online glossary article on biomorphic form specifies that while these forms are abstract, they "refer to, or evoke, living forms...". The article goes on to list Joan Miró, Jean Arp, Henry Moore, and Barbara Hepworth as examples of artists whose work epitomizes the use of biomorphic form.
