Underwater Ultrasound Confirms Pregnancies in Three Giant Manta Rays

Scientists applied underwater ultrasound technology to study giant manta rays. They successfully detected and confirmed pregnancies in three individuals. The scans provided direct evidence of reproductive status. These findings address the long‑standing mystery of manta breeding cycles. Researchers say the data offer rare insight into the species' elusive habits. The work demonstrates the feasibility of non‑invasive monitoring in the wild. It may help inform future conservation strategies for the threatened species. Further studies are planned to expand knowledge of manta ray reproduction.
