​

Tribe Zonarieae is a group of marine brown algae within the family Dictyotaceae of the order Dictyotales and class Phaeophyceae. Members of this tribe are typically characterized by broad, flattened thalli that may be fan-shaped, lobed, or concentrically banded, often exhibiting a more complex morphology than the ribbon-like forms found in some other dictyotalean algae. Genera such as Padina are commonly included within this tribe. Species of Zonarieae are widely distributed in tropical and subtropical seas, where they inhabit shallow coastal waters, coral reefs, lagoons, and rocky substrates.
