Ecosystem Roles
Grey nurse sharks help to regulate prey populations. Different species of lampreys (Petromyzontidae) prey on these sharks in a parasitic relationship, whereby the lamprey attaches to the shark, and extracts blood and other nutrients through a wound. These sharks also have mutualistic relationships with pilotfish (Naucrates ductor), which clean their gills and, in exchange, get to eat the scraps of food left behind in the gills.
Mutualist Species:
- pilotfish (Naucrates ductor)
Commensal/Parasitic Species:
- lampreys (Petromyzontidae)
