Cephalopholis argus (Blue-spotted Grouper)
Front view illustration of a West Indian Lantana. It is a weed of cultivated land, fence lines, pastures, rangelands, and waste places. It thrives in dry and wet regions and often grows in valleys, mountain slopes, and coastal areas. It is somewhat shade-tolerant and, therefore, can become the dominant understory in open forests or in tropical tree crops. In pastures it forms dense thickets which shade out and encroach upon desirable pasture plants. With time it can form pure stands over large areas, the
Lantana camara (West Indian Lantana)
Known as Koa haole (foreign koa) in Hawaii, or leucaena, is abundant as a weed in dry lowlands of Hawaii, often forming dense thickets in lowlands and lower mountain slopes of 2500 ft (762 m) altitude.

The Atlantic Rangia or wedge clam Rangia cuneata originates from the Gulf of Mexico. From there this bivalve colonized the Atlantic coast of North-America and Europe. The species mainly live in estuaries, brackish and freshwater. In ports, the Atlantic Rangia can become a pest as it establishes itself in industrial cooling pipes where it can obstruct optimal water flow.
