Info
The upper surface of the body of Urobatis halleri is generally light brown or tan, usually with dense, dark brown spots and a reticulated pattern of irregular lines.
The central portion of the disc is usually here with large, brown, circular markings overlaid on the background described.
Urobatis halleri gives birth to live young.
Age at sexual maturity has been estimated at 3, 8 years for females and 3.75 years for males, and the highest estimated age was 14 years!
For several years, there have been increasing reports of eye and spinal malformations, as well as an occurrence of black mucus on the dorsal surface and on some parts of the abdominal region of the animals.
The conditions may be due to one or more factors, including parasite infestation, tumors, or water pollution.
On southern California beaches, Urobatis halleri is responsible for numerous injuries to bathers who are stung when they accidentally step on the fish. The wound caused by its venomous sting can be painful, but is not fatal.
Not an animal for a native marine aquarium!
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.
Synonyms:
Urolophus halleri Cooper, 1863
Urolophus nebulosus Garman, 1885
Urolophus umbrifer Jordan & Starks, 1895
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.
