This discovery sheds light on the unique physiological adaptations that allow these marine giants to perform such vocal feats.
The research's primary focus involved examining humpback whales' laryngeal anatomy. Researchers found that specific adaptations in the whale's larynx enable it to produce song even without the continuous passage of air, contrary to what is typically required for sound production in most mammals, including humans.
The "Adella Shores" disappeared in 1909 during a routine voyage across Lake Superior, carrying a crew of 14 and a full cargo. Despite extensive searches, no trace was found until now. The shipwreck was uncovered using modern sonar technology, revealing the ship almost perfectly preserved on the lake’s cold, dark floor.
In a groundbreaking discovery, researchers have identified what is now considered the world's deepest underwater sinkhole, located off the coast of Mexico. This remarkable geological feature which reaches depths exceeding 1,300 feet (420 meters) could potentially house hidden caves and tunnels, offering new insights into Earth's subterranean mysteries.
Heat stress brought about by rising temperatures may cause impaired eyesight and more deaths of pregnant mothers and their unborn young.
In a study by the University of Adelaide, unborn octopuses and their mothers were exposed to three different temperatures: a control temperature of 19°C, 22°C to mimic current summer temperatures, and 25°C to match projected summer temperatures in 2100.
Compared to the other two groups, octopuses that were exposed to 25°C produced significantly fewer of some proteins responsible for vision.
