Types of Rays in Pacific Harbour
1. Eagle Rays
Overview: Eagle rays are a common sight in the waters around Pacific Harbour. Known for their distinctive spotted patterns and long tails, these rays are often seen gliding gracefully through the water, sometimes in small groups.
Characteristics:
- Appearance: Eagle rays have a flattened body with a distinctive pattern of spots or rings on their dorsal side. They have long, whip-like tails and pointed snouts.
- Size: They can grow up to 3 meters (10 feet) in length, including their tails.
- Behavior: Eagle rays are known for their agility and can often be seen swimming in open water or near reef edges. They are generally shy and tend to avoid divers, making sightings particularly special.
Where to Spot Them:
- Reef Edges: Look for eagle rays along the edges of coral reefs where they hunt for prey.
- Open Water: They are often seen swimming in mid-water, away from the reef, especially during drift dives.
2. Blue-spotted Stingrays
Overview: The blue-spotted stingray is easily recognizable due to its vibrant blue spots. These rays are relatively small and can often be found resting on sandy bottoms or hiding under coral ledges.
Characteristics:

- Coral Ledges: They often hide under coral ledges or in crevices during the day.
3. Marble Rays
Overview: Marble rays, also known as black-blotched rays, are larger and more robust compared to blue-spotted stingrays. They have a distinctive marbled pattern on their dorsal side and are often seen resting on the seabed.
Characteristics:
- Appearance: Marble rays have a dark, marbled pattern on their backs, with a thick, disc-shaped body and a short tail.
- Size: They can grow up to 2 meters (6.5 feet) across.
- Behavior: These rays are often seen resting on the seabed, using their powerful pectoral fins to stir up sand in search of food.
Where to Spot Them:
- Seabed: Look for marble rays resting on sandy or muddy seabeds near reefs.
- Cleaning Stations: Occasionally, they can be seen at cleaning stations where smaller fish remove parasites from their skin.
Tips for Spotting Rays
- Move Slowly and Calmly:
- Rays are sensitive to movement and can be easily startled. Move slowly and avoid sudden movements to increase your chances of observing them up close.
- Maintain Good Buoyancy:
- Practice good buoyancy control to avoid disturbing the seabed or damaging the reef. This also helps you approach rays without causing them to flee.
- Observe from a Distance:
- Respect the rays’ space and observe them from a distance. Avoid touching or chasing them to ensure both your safety and the well-being of the rays.
- Use a Dive Light:
- A dive light can help you spot rays hiding under ledges or resting on the seabed, especially during night dives or in low visibility conditions.
- Listen to Your Guide:
- Local dive guides are familiar with the habits and preferred locations of rays. Follow their instructions and tips to increase your chances of sightings.
