Regional Impacts
| Ecological Impact | Competition | |
| Settling of Bunodeopsis sp. A on seagrass (Zostera marina) killed plants in Mission Bay, by reducing the light reaching the leaf, covering the leaf surface, weighing down the leaf, bending it downwards, and matting leaves together (Williams and Heck 2001, cited by Williams et al. 2007). | ||
| Ecological Impact | Habitat Change | |
| Settling of Bunodeopsis sp. A on seagrass (Zostera marina) killed plants in Mission Bay, affecting the extent and health of eelgrass beds (Williams and Heck 2001, cited by Williams et al. 2007). | ||
| Economic Impact | Health | |
| Bunodeopsis sp. A can sting the exposed skin of swimmers and divers, through contact with the whole animal, or with autotomized tentacles, drifting in the waters. The stings are not extremely painful, but produce a sense of irritation and numbness (Ljubenkov, in SCAMIT 1999). | ||
