| | Case Study: Slipper Limpet |
 | | Transported mainly through oyster trade, the slipper limpet is often found in bays with oyster culture, but it can be carried on boat hulls, as well, and has been increasingly found in port regions. |
 | | In this way, slipper limpets compete with native mollusks for food and in areas where limpet populations are high, can outcompete oysters, clams, and mussels. |
 | | Slipper limpets attach together to form a chain, which allows limpets to reproduce quickly, and these chains of shells can become so dense that they completely blanket the sea bottom. |
