Established in November, this initiative marks a concerted effort to protect some of the most vulnerable dolphin species inhabiting the world’s rivers, many of which are on the brink of extinction.

The Global Declaration for River Dolphins was signed by nine countries, including Brazil, Colombia, and India, all home to river systems where these endangered species are found. This agreement is pivotal as it represents the first international commitment explicitly focusing on the conservation of river dolphins, which face habitat degradation, pollution, and fishing threats.

A fatal accident occurred off the coast of Sussex involving a recreational diver and a dive support boat, "Karin." This tragic event has led to an investigation by the Marine Accident Investigation Branch (MAIB), underscoring critical safety concerns within the diving industry.

Distressing images of turtles with plastic straws sticking out of their bodies or dead seabirds with stomachs brimming with synthetic trash justifiably attract public attention. 

However, this pollution extends to the microscopic scale from an increasing number of micro and nano plastics. These tiny particles permeate the depths of the oceans, posing significant health risks to marine creatures and humans alike. 

Sharks first appeared in the fossil record about the same time that plants covered the land, nearly half a billion years ago. Evolution has made them so perfect that they have retained their main characteristics over all of this abyss of time. But despite their formidable lineage, modern sharks face unprecedented threats and challenges that endanger their diverse roles within ecosystems.

When sea turtles get trapped in fishing nets and are brought to the surface, they can suffer from gas emboli because their normal diving processes are disrupted. This can cause abnormal gas build-up in their organs. 

To address this, marine veterinarians worldwide are developing methods to understand the possible consequences of this and to determine the most ideal treatment for them. 

The shipwreck was found at a depth of 1800m, some 90km from shore, during a survey by a natural gas company, Energean. The wreck is believed to date from a period known for significant cultural and trade exchanges across the region. Artefacts recovered from the site include pottery, weapons, and tools, suggesting that the ship was part of extensive trade routes connecting ancient civilizations across the Middle East, Egypt, and possibly even further afield.

Marine scientists from Oregon State University have observed a concerning trend in the body size of gray whales off the Pacific Northwest coast. Since around 2000, these whales have shown a significant decrease in length, raising alarms about their overall health and the state of the ecosystem.
