What parasites do lobsters have?

Lobsters can host various parasites, including the parasitic copepod Pennella spp., which attaches to the lobster and can cause physical damage. They may also be affected by the protozoan Hematodinium spp., leading to a condition known as "hemolymph parasite disease," which can be lethal. Additionally, some lobsters can harbor trematodes, which are flatworms that can affect their health and behavior. These parasites can impact lobster populations and fisheries, highlighting the importance of monitoring their health in marine ecosystems.
