Quick answer
Nurse Sharks (Ginglymostoma cirratum) typically live around 20–25 years in the wild. Wild averages fall when predation, disease, or habitat loss rise; managed populations can live longer with stable food and veterinary care.
Key takeaway

Nurse Shark lifespan in the wild
Field and museum records place most nurse sharks near 20–25 years in the wild. That figure blends ages at death across regions, so treat it as a planning range. Body size (75–110 kg (165–240 lb); max about 150 kg) and risk lifestyle both shape the average.
What shortens nurse shark lives
Predation, infectious disease, injury, food shortages, and habitat fragmentation cut survival. Roadkill and human conflict matter wherever nurse sharks share landscapes with people.
What helps nurse sharks live longer
Connected habitat, low chronic stress, and reliable food support longevity. For captive or domestic relatives, species-correct diet and veterinary screening matter more than generic “pet” advice.
Nurse Shark life stages
Juveniles usually face higher mortality than prime adults. Older animals may move less, show dental wear, or lose body condition — useful signs when ageing nurse sharks in the field.
Diet and ecological role
Nurse Sharks feed on carnivore — fish, crustaceans, molluscs, and stingrays. Foraging shifts with season and local abundance. As fish, they influence food webs — controlling prey, dispersing seeds, or shaping habitat through feeding and movement.
Conservation and coexistence
Listed as Vulnerable on the IUCN Red List. Habitat loss, hunting, and climate change threaten many populations. Responsible ecotourism and community conservation help in parts of their range. Never approach or feed wild nurse sharks.
