If you have ever snorkelled or dived in the Maldives, you might have spotted a large, slow-moving shark resting quietly on the ocean floor. This is likely a nurse shark, a species that appears everywhere in these tropical waters but remains misunderstood by many visitors. Despite their intimidating size and shark-like appearance, nurse sharks are gentle creatures that pose little threat to humans. Understanding their behaviour and what it means to encounter one can transform your underwater experience from apprehension to awe.
What Are Nurse Sharks?
Nurse sharks (Ginglymostoma cirratum) are a species of bottom-dwelling sharks found in warm, shallow waters, including the coral reefs and lagoons of the Maldives. They can grow up to 3.2 meters (about 10.5 feet) in length, making them one of the larger shark species you might see while diving here. Their bodies are stout with broad heads and rounded fins, and their skin has a rough texture.
Unlike the fast-swimming sharks often portrayed in movies, nurse sharks move slowly and deliberately. They spend much of their time resting on the seabed during the day, often in groups, and become more active at night when they hunt for food.
Why Nurse Sharks Are Harmless to Humans
One of the most common concerns among snorkellers and divers is safety. Nurse sharks have a reputation that might cause unease, but the truth is they are generally harmless to humans. Here’s why:
Docile Nature: Nurse sharks are not aggressive. They prefer to avoid confrontation and will usually swim away if disturbed.
Feeding Habits: Their diet consists mainly of small fish, crustaceans, and mollusks. They use their strong suction to pull prey from crevices in the reef.
Slow Movements: Their slow, calm swimming style means they rarely pose a threat.
Biting Only When Provoked: Nurse sharks have powerful jaws and can bite if they feel threatened or are provoked, but such incidents are extremely rare and usually involve accidental contact.
For snorkellers and divers, this means that nurse sharks are safe to observe from a respectful distance. They are curious but not confrontational, making encounters peaceful and memorable.
What It Means to Encounter a Nurse Shark While Snorkelling or Diving
Seeing a nurse shark up close is a unique experience that many visitors treasure. Here’s what you can expect and how to make the most of the encounter:
Stay Calm and Respectful: Nurse sharks respond to calm behaviour. Avoid sudden movements or loud noises.
Keep Your Distance: Maintain at least a few meters between you and the shark. This gives the animal space and reduces stress.
Observe Their Resting Spots: Nurse sharks often rest in caves or under ledges during the day. Spotting one in these places is common and a sign of a healthy reef ecosystem.
Night Dives Offer a Different View: Since nurse sharks are more active at night, diving after dark can reveal their hunting behaviour.
Use a Guide: Local dive guides know the best spots to find nurse sharks and can provide safety tips and interesting facts.
Encountering a nurse shark is a reminder of the rich marine life thriving in the Maldives and an opportunity to appreciate the ocean’s diversity.
The Role of Nurse Sharks in the Maldives Ecosystem
Nurse sharks play an important role in maintaining the balance of coral reef ecosystems. By feeding on bottom-dwelling creatures like sea urchins and crustaceans, they help control populations that could otherwise damage the reef. Their presence indicates a healthy environment, which benefits other marine species and supports the Maldives’ reputation as a top diving destination.
How to Protect Nurse Sharks and Their Habitat
As visitors and ocean lovers, protecting nurse sharks and their environment is crucial. Here are some practical steps:
Avoid Touching or Chasing Sharks: This stresses the animals and can alter their natural behaviour.
Do Not Feed Wildlife: Feeding disrupts their diet and can lead to aggressive behaviour.
Support Sustainable Tourism: Choose operators who follow responsible diving and snorkelling practices.
Reduce Plastic Use: Marine debris harms sharks and other sea creatures.
Respect Marine Protected Areas: These zones safeguard critical habitats for nurse sharks and other species.
By following these guidelines, you help ensure nurse sharks continue to thrive in the Maldives for future generations.
