Characteristics

The blue spotted ray measures approximately 17 inches in diameter and 28 inches in length. This ray is characterized by a dark green body covered with blue spots. It also has a white underbelly. This ray has venomous spines that are hidden so it can strike its prey without warning.


Breeding

The female blue spotted ray gives birth to up to seven pups per litter. The babies measure between 6 and 13 inches long at the time of birth. The mating season for the blue spotted ray is during October and November.


Behavior

The blue spotted ray lives in ocean waters and prefers to make its home near coral reefs in order to be close to food sources. It subsists on shrimp, fish, crabs, worms and other small life forms that live in shallow waters. When hunting, the blue spotted ray pins its prey to the floor of the ocean and then uses the crushing plates on either side of its mouth to eat.


History

The first written record of the blue spotted ray was made in 1841 by an ocean explorer named Heinrich Kuhl, who discovered this stingray in the waters off the coast of Java, Indonesia. It is believed that there are five species of blue spotted stingray. This particular stingray can be found in the ocean waters between Indonesia and Japan, all the way to the northern coasts of Australia.


Present Status

The blue spotted ray is large in population numbers and is in no danger of extinction at this time.
