Researchers may have an answer to the mystery of why an anglers' favorite, the golden trevally, is so widespread globally—the prized fish might 'hitchhike' with whale sharks.
Associate Professor Nathan Waltham from James Cook University's Center for Tropical Water and Aquatic Ecosystem Research took part in a preliminary investigation with a team of coastal ecology academics.
"They're found in a band from the east coast of Africa across to the west coast of North America and from islands south of Japan to northern Australia. Golden trevally appear not to be affected by biogeographic boundaries that constrain the distributions of most other species with reef or coastal associated adults.
, which could explain the unusually widespread distribution of the trevally and suggests a novel nursery relationship," said Dr. Waltham.Dr. Waltham said 60% of the images featuring trevally in close association with other sea creatures showed them with whale sharks.

Researchers demonstrate high-fidelity transmission of information via novel electronic-optical systemTransferring optical information in free space with large bandwidth and high transmission capacity has gained significant attention in various applications, such as remote sensing, underwater communication, and medical devices. Nevertheless, unpredictable, unknown phase perturbations or random diffusers within the optical path pose great challenges, limiting the high-fidelity transmission of optical data in free space. Adaptive optics presents a potential solution that can correct for random distortions dynamically; however, spatial light modulators and iterative feedback algorithms employed inevitably increase both cost and complexity.
