  • The other main order of cartilaginous fishes to be found

  • around the Andaman's reefs is the rays,

  • and most common of these is the bluespotted stingray.

  • This stingray's coloration and common name

  • make it often confused with the more circular blue-spotted stingray

  • found in the Gulf of Thailand,

  • which belongs to a different genus.

  • The bluespotted stingray is found on sandy bottoms

  • at sites such as East of Eden in the Similans.

  • The neutral color of the larger Jenkins whipray

  • camouflages it well against the seabed.

  • This ray has a pair of sharp and venomous spines near the base of its tail,

  • and the name whipray comes from the ray's ability to whip it's long tail over fast

  • and administer a nasty sting to a predator at any part of its circumference.

  • The ray takes water in through its spiracle, a hole just behind the eye.

  • This water can be blown out through the mouth

  • to excavate food from the substrate.

  • Another large stingray common to the area is the blotched fantail ray.

  • This impressive species can grow nearly 2 meters in diameter

  • and is often one of the highlights of dives in the Andaman.

  • Blotched fantail rays are most impressive when they aggregate in shoals.

  • Occasionally they can be witnessed in large numbers.

  • I encountered this shoal of some 30 individuals at Black Rock.

  • They had possibly gathered to mate.

  • Another visitor to Black Rock and other deep-water sites

  • is the spotted eagle ray.
