Info
The front half of the tail can have up to 7 barbs or stingers on the upper side, with which the ray can inflict a painful, sometimes even venomous sting on any attacker by flinging its tail upwards in an arc, similar to a scorpion sting.
The barbs, which can be up to 25 cm long, are razor-sharp and sometimes hidden under a sheath that only comes out when attacked.
The sting can break off after a bite and become lodged in the victim, leading to severe inflammation if it is not surgically removed quickly.
Stingrays can grow new spines, regardless of whether they use them or not.
Not all rays have spines. Devil rays, manta rays, butterfly rays and some that are sometimes referred to as "rays" (such as guitar rays, electric rays and certain rays) do not have spines.
Caution:
People have already died from stingray bites, including the well-known Australian documentary filmmaker, adventurer and zoo director of the Australian Zoo, Steve Irwin "The Crocodile Hunter" from Australia in 2006.
Even if the sting injuries are not fatal, the sting causes extremely painful and deep wounds in any case, and there is also a risk of parts of the sting breaking off in the wound and subsequent surgery becoming necessary.
The situation becomes particularly dramatic if toxins enter the body via the sting.
Occasionally beach visitors accidentally step on stingrays, some of which are buried in the sand near the beach, resulting in a painful, serious wound to the foot, so always wear bathing shoes as a minimum.
Snorkelers and divers should never swim over stingrays lying on the bottom, as the stingray can quickly fling its muscular, whip-like tail around and stab in defense.
In any case, seek medical attention immediately or seek immediate transportation to the nearest hospital.
The stated size of 38 cm does not refer to the length of the ray including the tail, but to the diameter of the body disc.
Rays are bottom feeders, they settle over their prey to press it against the bottom with their disc, then bend their disc flaps to maneuver the prey into their mouth.
Color.
The dorsal surface of living rays is pale yellowish-brown in the center and spotted blue
The blue spots, which serve as a warning of the strong toxicity of the blue-ringed octopus of the genus (Hapalochlaena) and the blue-spotted stingray Taeniura lymma, do not allow the conclusion that Neotrygon rays are toxic!
Rays are gentle creatures that search for food in the wild by flapping their wings and seeking out prey hiding in the sandy bottom, and never use their spines when hunting!
Their spines are only used for defense, especially against their enemies (mainly sharks).
Most human victims are stung on the ankles or feet when they accidentally step on a ray.
Fishermen have also been known to be stung on the boat deck while sorting out their catch, which includes stingrays.
Pregnant females usually only give birth to one live young with a disk diameter of up to 12 cm.
Etymology. The epithet "orientalis" refers to the Southeast Asian distribution of this member of the blue-spotted masked fish complex within the genus Neotrygon .

If you want to find out about the size of rays in specialist literature, usually written in English, you will often come across two abbreviations that ultimately mean the same thing: DW or WD.
If you look at FishBase, WoRMS or first descriptions of rays, you will find these abbreviations.
The total length including shoal is only rarely given, the TL.
