bluespotted stingray (Neotrygon kuhlii) by tbanny The bluespotted stingray (Neotrygon kuhlii) or Kuhl’s stingray, is a species of stingray of the Dasyatidae family. It was recently changed from Dasyatis kuhlii in 2008 after morphological and molecular analyses show that it is part of a distinct genus, Neotrygon.[1] The body is rhomboidal and colored green with blue spots. Maximum disk width is estimated 46.5 centimeters (18.3 in).[2] It is popular in aquaria but usually not distinguished from the bluespotted ribbontail ray. The ribbontail has a rounded body, is a brighter green with brighter blue and more vivid spots, but the bluespotted stingray is larger.[3] The stingray’s lifespan is estimated thirteen years of age for females and ten years for males.[4] The bluespotted stingray preys on many fish and small mollusks. The bluespotted stingray is also generally found from Indonesia to Japan, and most of Australia. The bluespotted stingray is also targeted by many parasites such as tapeworms, flatworms, and flukes.

Leopard whipray - Himantura leoparda

Encountered in the Indo-Pacific from South Africa to Australia, the leopard whipray has a striking pattern of dark brown rings on its dorsal side that gave it its name. Like all species in the Himantura genus, known as the whiprays, it has a very long, thin tail that lacks a dorsal or caudal fin and can measure more than three times the length of its disc. Adults can reach approximately 5.9ft in width and a total length of about 13ft with an intact tail. Due to confusion with the closely related honeycomb and reticulate whiprays, the leopard whipray is not well known. It is heavily fished in parts of Indonesia for its meat and possibly other parts using bottom trawls, tangle nets, and longlines, and has not been classified by the IUCN at this time.


Bluespotted ribbontail ray - Taeniura lymma

Common throughout nearshore Indo-Pacific reef habitats, the bluespotted ribbontail ray can be easily identified by its electric blue spots and two stripes on the tail. A small species that rarely exceeds 2.5 ft in total length, it hunts at night during high tides and retreats to the reef to shelter during the day when the tide recedes. Prey, usually benthic invertebrates and fish, are trapped by the ray’s body and maneuvered towards the mouth by the pectoral fin disc. There are usually two - sometimes one - serrated venomous spines on the tail. Though currently abundant, the IUCN classes this species as Near Threatened due to the widespread destruction of coral reefs and fishing pressure.
