Mantas and stingrays are relatives and belong to the same subclass Elasmobranchii (shark, rays and skates). There are only 2 different species of mantas (alfredi and birostris). In comparison, there are over 100 different stingray species.
In the course of their clinical work or during leisure activity, family physicians occasionally may encounter patients with injuries from marine creatures. Poisoning, envenomation, and direct trauma are all possible in the marine environment. Ciguatera poisoning can result from ingestion of predatory fish that have accumulated biotoxins. Symptoms can be gastrointestinal or neurologic, or mixed. Management is mostly symptomatic. Scombroid poisoning results from ingestion of fish in which histamine-like substances have developed because of improper refrigeration. Gastrointestinal and systemic symptoms occur. Treatment is based on antihistamines. Envenomations from jellyfish in U.S. waters and the Caribbean are painful but rarely deadly. Household vinegar deactivates the nematocysts, and manual removal of tentacles is important. Treatment is symptomatic. Heat immersion may help with the pain. Stingrays cause localized damage and a typically severe envenomation. The venom is deactivated by heat. The stingray spine, including the venom gland, typically is difficult to remove from the victim, and radiographs may be necessary to localize the spine or fragment. Surgical débridement occasionally is needed. Direct trauma can result from contact with marine creatures. Hemorrhage and tissue damage occasionally are severe. Infections with organisms unique to the marine environment are possible; antibiotic choices are based on location and type of injury. Shark attacks, although rare, require immediate attention.

Many marine creatures are venomous, and beachgoers experience envenomation regularly. Jellyfish and related creatures (Cnidaria), sea urchins (Echinodermata), and stingrays (Chondrichthyes) are some of the more easily identified marine creatures involved with envenomations.
Although many fish are venomous, stingrays are the most clinically important, accounting for an estimated 1,500 (mostly minor) injuries in the United States annually. These creatures partially bury themselves in the sandy bottom of the ocean shallows, where water enthusiasts may accidentally step on them.
Local law enforcement and the federal government have resisted judicial requests for information about the use of stingrays, refusing to turn over information or heavily censoring it.[59][60] In June 2014, the American Civil Liberties Union published information from court regarding the extensive use of these devices by local Florida police.[61] After this publication, United States Marshals Service then seized the local police's surveillance records in a bid to keep them from coming out in court.[62]
Guests can watch, touch and occasionally feed the unique and fascinating stingrays as they glide through a warm saltwater pool in this habitat! The sharks are a little too shy for petting, but you may be lucky enough to have one touch you briefly as it swims by. Stingrays at Caribbean cove is a seasonal habitat.
Stingrays and other ocean animals are often accidentally caught during commercial fishing for other fish. It is important that consumers purchase seafood from suppliers that farm or fish in ways that will ensure the long-term health of the world's oceans, rivers and lakes. Our stingrays and sharks eat fish that are from sustainable sources, and so should you!
Animal and veterinary care for the stingrays is supervised by a full-time exhibit supervisor and an assistant exhibit supervisor from Living Exhibits, a Las Vegas-based corporation that produces and manages interactive exhibits for zoos, aquariums and museums.
So, are stingrays dangerous? Catastrophic stingray attacks on humans are extremely rare with only two recorded fatalities in Australia since 1945, and this statistic includes the tragic accident involving Steve Irwin.
It is only when a stingray feels threatened that divers have a cause for concern. Stingrays harbor a barb for one purpose, and that purpose is self-defense. Stingrays only use their barb as an involuntary reflex if they feel threatened and as a deterrent to predators such as sharks.
A major goal of education is the debunking of miseducation. It is becoming increasingly concerning that the death of Steve Irwin in 2006 continues to install a worldwide fear of stingrays, a fear that is frankly unjustified.
A stingray is a sea animal with a whip-like tail. The tail has sharp spines that contain venom. This article describes the effects of a stingray sting. Stingrays are the most common group of fish that sting humans. Twenty-two species of stingrays are found in US coastal waters, 14 in the Atlantic and 8 in the Pacific.
"This panel shows a mother Killer Whale teaching her calf to hunt for stingrays. The whales are shown diving down to the seafloor, where they bump the stingrays with their noses. The stingrays are startled and forced up toward the surface. Once in the open water, and off of the ocean floor, they become easy prey." - Phil Gray
The primary predators of southern stingray adults are hammerhead sharks. Both scalloped hammerheads and Great Hammerheads have been observed using their wide heads to pin stingrays to the seafloor, wildly biting them until they can no longer move. When dissecting large hammerheads, scientists often find numerous (perhaps dozens) of southern stingray spines lodged in their jaws. Juvenile southern stingrays are eaten by other species of sharks as well.
This species is not generally eaten by people, but it is often captured accidentally in bottom trawls and other net fisheries targeting other species. Scientists believe this to be a hardy species, however, and are hopeful that accidentally captured individuals may be released alive and survive their human encounter. The southern stingray is one of the most common species of large, whiptail stingrays found in public aquariums.
Five cownose rays, two yellow stingrays and one Atlantic stingray are among the animals that died today at the National Mississippi River Museum & Aquarium in Dubuque. According to a press release from the Dubuque museum, an additional cownose ray remains in stable condition
The stingray exhibit is closed as staff investigates the death of the stingrays. Stingray feedings and touch tank capabilities at the Delta in the National River Center are on hold until further notice
According to a statement issued Tuesday, the Lifeguard Services Division is advising sea bathers and visitors to Manzanilla Beach that there has been an increase in the presence of stingrays along the shallow coastline of the beach.
The Ministry said while there were no reports of anyone being injured by stingrays, "it is a well-known fact that throughout the world stingrays have been known to inflict excruciating injuries on swimmers and beachgoers annually".
According to the National Geographic, stingrays are commonly found in the shallow coastal waters of temperate seas. They spend the majority of their time inactive, partially buried in sand, often moving only with the sway of the tide.
The stingray's spine, or barb, can be ominously fashioned with serrated edges and a sharp point. The underside may produce venom, which can be fatal to humans, and which can remain deadly even after the stingray's death 2ff7e9595c
