Tochuina tetraquetra, common name the giant orange tochui, is a species of sea slug, a tritonid nudibranch, a marine gastropod mollusk in the family Tritoniidae.[2]

Bergh (1879) used the name Tritonia tetraquetra in a sense different from Pallas (1788). The oldest valid name for Tochuina tetraquetra sensu Bergh, 1879 is Tritonia gigantea Bergh, 1904.[2]
