Competition
- —Lobsters are in the 1st level of carnivores and eat mainly herbivores.
- —They face the most competition with blue crabs for shelter in cracks and caves as well as food because their diets are very similar.
- —Lobsters also compete with sea urchins for shelter. The sheer abundance of sea urchins in certain areas makes shelter a substantial limiting factor for lobsters.
—Although lobsters are known to be predatory, there scavenger-like traits allow them to roam the ocean floor searching for food, which ultimately reduces competition. Additionally, their powerful claws can be quite helpful in the establishment of dominance over other smaller crustaceans like crabs.
