“There it is on the sandy bottom — electric blue spots on a bright yellow-orange disc, barely moving, beautiful and quietly deadly if disturbed.”
Blue-Spotted Lagoon Ray – Jewel of the Great Barrier Reef Shallows
The Blue-Spotted Lagoon Ray (Taeniura lymma), also known as the Bluespotted Fantail Ray (its standard Australian name) or the Blue-Spotted Ribbontail Ray, is one of the most instantly recognisable — and most photographed — rays on the Great Barrier Reef. Its vivid electric-blue spots set against an orange-yellow body make it unmistakable, and its preference for shallow sandy areas makes it one of the most commonly seen rays on snorkelling tours.

About the Blue-Spotted Lagoon Ray
Blue-Spotted Lagoon Rays are relatively small — adults typically measure 25–35cm across the disc and up to about 70cm long including the tail — and are found in shallow sandy areas, seagrass beds, coral rubble zones, and under coral ledges throughout the Indo-Pacific. On the Great Barrier Reef, they’re a feature of the shallow reef flats and lagoon areas around coral cay islands and sheltered reef systems.
They feed on molluscs, worms, crabs and shrimps that they uncover by fanning sand away with their fins, often moving into shallow sandy areas on the rising tide. During the day they’re often seen resting under coral overhangs or in the shade of bommies; during tidal flows they become more active as food is stirred up.
Important Safety Note
Like most stingrays, the Blue-Spotted Lagoon Ray has venomous spines on its tail, usually two, set well back from the body. While they are not aggressive, an accidental encounter — particularly standing on a buried or resting ray — can result in a painful and potentially serious sting.
Visitors are advised to shuffle their feet when walking in shallow sandy areas, avoid touching rays, and give them space to move away naturally.
Where to See Blue-Spotted Lagoon Rays
Blue-Spotted Lagoon Rays are common throughout the Great Barrier Reef, particularly around coral cay islands like Low Isles (Port Douglas), Green Island (Cairns), and the Whitsunday Islands. They’re regularly spotted by snorkellers in very shallow water — often less than a metre deep.

Blue-spotted lagoon rays are often seen in shallow water around coral cays such as Green Island and Low Isles, though sightings are never guaranteed.
