A recent article by Sam Fletcher begins with the gripping account of a wildlife videographer, Scott Fairchild. Using a drone, he captures a heart-stopping moment when a great white shark repeatedly approaches a lone swimmer off the coast of San Diego. Yet suddenly the shark veers away and disappears. Fairchild states that he has seen countless such encounters between swimmers and white sharks off the Californian coast.

In a significant environmental move, Greece has announced plans to invest €780 million in the creation and maintenance of marine parks across the country. These initiatives aim to protect marine biodiversity and make Greece a leader in marine conservation in Europe, including a ground-breaking ban on bottom trawling in all marine protected areas.

In a pioneering study published in Nature Communications, researchers have made significant progress in decoding the communication system of sperm whales, suggesting that their patterns of clicks—known as codas—may be the closest animal equivalent to human language.

For fish and other water-breathing animals like sharks and rays, reaching reproductive maturity is a crucial milestone that impacts their entire life history. The size at which they reach maturity, coupled with their subsequent growth rate, affects their longevity and reproductive capacity. Now, researchers have pinpointed a specific pH threshold, termed the "reproductive respiration threshold" (RRT), which kickstarts the hormonal processes leading to maturation.

Unveiled by an international team of archaeologists and palaeontologists, this finding provides an intriguing glimpse into the ancient seas and the life of a previously unknown apex predator of the Late Cretaceous period.

This remarkable finding, uncovered during a recent expedition led by Greenpeace, has piqued considerable intrigue among scientists owing to the rarity of smooth hammerhead shark sightings during their early developmental stages.

According to the findings, more than half of the 208 non-target species ensnared in the nets over the past eight months met a grim fate, with 134 animals, including critically endangered grey nurse sharks and leatherback turtles, among the casualties. The figures, made public as the nets were removed for the season, highlight the significant toll the program exacts on marine biodiversity.

The ozone layer is back on our radar. Although its condition has improved after the Montreal Protocol was implemented, the hole reappears every spring over the Antarctic. 

In recent years, it is no longer just a winter phenomenon anymore; it's stretching into the early summer, coinciding with crucial times in the life cycles of local wildlife and emerging vegetation, exposing them to the sun's ultraviolet rays. As our planet changes, the timing of this exposure could have profound effects on the delicate ecosystems of the Antarctic.

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.
