giant saltwater stingray
Once it was aboard the research vessel, a pipe was used to keep oxygenated water flowing over the ray's gills while the team conducted their workup, a process that involves various measurements and observations.
"It was a big surprise for us," he told the Andelou Agency.
This mindbogglingly large ocean sunfish was encountered by photographer Miguel Aleixo off the coast of Portugal.
Saltwater rays that don't belong to the stinging suborder (Myliobatoidei) can grow even bigger.__Top header image: Simone Carletti/Flickr, Sarah Keartes is a science and wildlife journalist based in the Pacific Northwest. "This was the case for the researchers in Turkey, too. "It's a very surprising turn of events in most cases, and every time I have witnessed it, the offspring were pretty far along in their development. During a recent survey off the coast of Turkey, scientists hauled up one of the largest saltwater stingrays ever found.
"In water, the female is supported by her natural buoyancy, but once she is brought on a boat, all her weight now rests on the underside, which may push the offspring out," he explains. Giant Stingrays shed & re-grow their spines on a regular basis regardless of whether they use them. The Thailand companies are not always as forthcoming about the potential risks of tangling with one of the bigger specimens, who’ve been known to pull boats upstream and even underwater.
If that’s not enough to get your attention, it’s also arguably the most bizarre-looking one with its outlandishly wide, pancake-flat body and whip-like tail.

Farrugia adds that there is also another possibility: changes in the environment (going from water to air) could physically push the babies out. The fish's "wingspan" was reportedly 2.21 metres – if confirmed, that size would surpass the. The eight pups born on the vessel were delivered without a visible yolk sac, which indicates that the babies were likely very close to term. When she’s not serving up stories, she can be found climbing mountains with a board on her back.
Lately, Thailand adventure tourism impresarios have been promoting Giant Stingrays as a fun challenge for sport fishermen because of their impressive size & reputation for fighting hard when hooked.
In a world bursting with news, nature is our niche – and we love it that way. That’s especially true of our planet’s countless wild species: big and small, threatened and persecuted, complex and fascinating. Sharks and rays are very sensitive to stress, and it's not uncommon for females to go into labour after being caught (either on a line, or by a predator). Even in a healthy, fully developed brood, only a fraction of ray pups actually make it to adulthood – but we can at least tell you that each of these babies swam away without any trouble. It is found in large rivers and estuaries in Southeast Asia and Borneo, though historically it may have been more widely distributed in South and Southeast Asia. Because it was only recently discovered, there’s relatively little information available about the Giant Stingray, compared to more familiar species of fish. Rays are not generally aggressive, but may attempt to use the spine in defense if it is afraid or agitated.
