Sea Turtles in Mauritius
Green and hawksbill turtles move through Mauritian lagoons, coral reefs and deeper coastal waters, connecting feeding habitats across the tropical Indian Ocean.
- Green and hawksbill turtles may be encountered
- Seagrass and coral habitats provide important food
- Turtles must surface regularly to breathe
- Touching and chasing can cause serious stress
- Wild sightings can never be guaranteed
Ancient ocean travellers
Sea turtles connect Mauritius with the wider Indian Ocean
Sea turtles spend most of their lives in water, yet they remain reptiles that must breathe air. Their slow movements can appear calm and effortless, but every dive, feeding period and surface breath follows an important natural rhythm.
Turtles seen around Mauritius may use lagoons, reef edges, rocky areas and seagrass habitats for feeding and resting before travelling across much larger ocean regions.
A respectful encounter allows the animal to continue feeding, swimming or surfacing without having to avoid people or boats.
Turtle species
Green turtles and hawksbill turtles
Both species may occur in the waters around Mauritius, although individual sightings depend on habitat, food availability and natural movement.
Green Turtle
Green turtles often feed in shallow coastal habitats. Adults are strongly associated with seagrass and other marine vegetation.
Hawksbill Turtle
Hawksbills have a narrower, curved beak and are closely associated with coral reefs and rocky feeding habitats.
Occasional visitors
Other marine turtle species may move through the wider region, but encounters around Mauritius are generally less predictable.
Identification
How green and hawksbill turtles differ
Typical green turtle features
- Rounded head and smoother facial profile
- Broad oval shell
- Patterned brown and olive colouring
- Often associated with seagrass feeding areas
- Powerful front flippers for long-distance swimming
Typical hawksbill features
- Narrow head with a strongly curved beak
- Overlapping shell scales
- Rich amber, brown and dark patterning
- Often associated with reefs and rocky habitats
- Agile movement through complex coral areas
Turtle habitats
Where sea turtles feed, rest and travel
Seagrass beds
Shallow seagrass areas provide food for green turtles and nursery habitat for many other marine species.
Coral reefs
Reef structures provide shelter and feeding opportunities, especially for hawksbill turtles.
Reef channels
Channels connect lagoons with open water and may be used by turtles moving between coastal habitats.
Main threats
Why sea turtles remain vulnerable
Their long lives and wide-ranging movements expose turtles to many different threats across the ocean and coastline.
Plastic pollution
Turtles may swallow plastic or become trapped in discarded material.
Fishing gear
Lines, hooks and nets can cause entanglement, injury and drowning.
Habitat decline
Damage to coral reefs and seagrass reduces feeding opportunities.
Human disturbance
Chasing, touching and crowding can interrupt feeding and breathing.
A turtle at the surface must be allowed to breathe
Sea turtles cannot breathe underwater. They regularly return to the surface for air, and the timing of that breath is controlled by the animal's activity and physical condition.
Swimmers or boats that surround a turtle may block its route, cause panic or force it to remain submerged longer than it would naturally.
Visitors should never position themselves above a turtle or between the animal and open water.
Responsible snorkelling
How to observe turtles without disturbing them
Keep your distance
Use calm fin movements and allow the turtle to choose whether it remains nearby.
Avoid sudden movement
Fast pursuit, diving directly above the animal and splashing may interrupt feeding or resting.
Limit group pressure
Several swimmers should not surround one turtle or compete for the closest photograph.
Before entering the water
Practical safety and wildlife guidance
Recommended preparation
- Check current, wind and visibility
- Use correctly fitted snorkelling equipment
- Stay within personal swimming ability
- Enter from sand rather than coral or seagrass
- Follow local protected-area instructions
What visitors should avoid
- Touching shells, flippers or heads
- Feeding turtles
- Holding a turtle underwater
- Blocking access to the surface
- Standing on coral or seagrass while watching
Frequently asked questions
Sea turtles in Mauritius
Which sea turtles can be seen around Mauritius?
Green turtles and hawksbill turtles are the species most commonly associated with Mauritian coastal waters.
Are turtle sightings guaranteed?
No. Sea turtles are wild animals, and their presence depends on natural movement, food availability and sea conditions.
Can visitors touch sea turtles?
No. Touching may cause stress, alter behaviour and interfere with feeding, resting or surfacing.
What do green turtles eat?
Adult green turtles are strongly associated with seagrass and marine vegetation, although diet can vary with age and habitat.
What do hawksbill turtles eat?
Hawksbill turtles feed within reef habitats and use their narrow beaks to reach food in crevices and complex structures.
Why do turtles come to the surface?
Sea turtles are reptiles with lungs and must return to the surface regularly to breathe.
How can visitors protect turtles?
Keep a respectful distance, avoid contact, never feed them, protect coral and seagrass, and remove plastic or fishing waste safely.
