Halodule wrightii (shoalweed) is a plant species native to seacoasts of some of the warmer oceans of the world. It has been reported from California, Texas, Florida, Louisiana, Mississippi, Alabama, North Carolina, Maryland, Yucatán, Quintana Roo, Tabasco, Costa Rica, Belize, Panamá, Cuba, Trinidad & Tobago, Venezuela, Brazil, Australia, Cape Verde, and Madagascar.
Some publications cite US specimens by the synonym, Halodule beaudettei, but the two names represent the same species.
Halodule wrightii is an herb growing in salt-water marshes in intertidal regions, often submerged at high tide but emergent at low tide. It has flat leaves up to 20 cm long, dark reddish-brown, with a few teeth on the margins. Fruits are spherical to egg-shaped, about 2 mm across.
