The habitat utilization was recorded during the land-based observations and showed that the stingrays spent most of their time feeding in the soft sediment habitats, thus taking advantage of the soft sediment algal turf and sandy shoal habitats that dominate the shallow marine environments within the...
Patch of denticles and low thornlets on nape, back, and tail. Tail narrow and short; slightly longer than disc width. Tail tapers to caudal sting then thins slowly to tip. Narrow ventral finfold extends to tip of tail; finfold height slightly less than tail height beyond caudal sting. ...
Determine the population demographics of the three predominant species in the St Joseph lagoon: cowtail, porcupine and mangrove stingrays. Determine the diet of cowtail, porcupine and mangrove stingrays. Determine the habitat use and movement of the porcupine stingray using acoustic tracking....
The yellow stingray is under threat from habitat loss due to climate change as the species is dependent on coral reef and seagrass beds. It is also threatened by artisanal fisheries exploitation for food and for use as bait in parts of its range in some central American countries, but the ...
but they are retained and sometimes directly targeted in Central and South America. In the US and Mexico, Southern Stingray populations are relatively stable, but in Colombia, the it is assessed as Near Threatened due to over-exploitation and habitat degradation. Overall, the species is thought ...
Band of heart-shaped denticles on central disc. A row of thorns extend along midline from nape to caudal sting. Thorns on tail greatly elongated and spear shaped. 1-2 thorns on each shoulder; sometimes absent. Tail narrow based, round in cross section, tapering gently to caudal sting, then...

Adding substrate simulates a ray's natural habitat, the softer the better to allow for digging. However, this ultimately is personal preference. A ray will do just as well in an aquarium without substrate.Behaviour[edit]In the wild, the stingray spends most of its time at the bottom of ...
Habitat Tropical seas. On sand and mud, sometimes adjacent to reefs. From shallow estuaries to at least 60m. Occasionally enters freshwater. Distribution Indian Ocean and equatorial western Pacific. Madagascar, East Africa, Arabian Peninsula (including the Persian Gulf), India, Southeast Asia, ...
The tropical fed stingrays also exhibited essential FA ratios, specific to both species and habitat, comparable with those of elasmobranchs and squid from cold-water environs, implying that the provisioned food does not provide a similar nutritional lipid composition to that eaten in the wild.
