Mystery Skin Disease Affecting Malaysia's Reef Sharks

14 June

Whitetip Reef Sharks off Sabah, Borneo were seen with lesions and spots on their heads.  Other shark species off Sipidan Island are also showing similar signs of the disease. Marine biologists are uncertain what’s causing it. But a rise in sea temperature could be the culprit.

In Search of Deep-Sea Sharks

11 June

A week-long expedition off the Azores is aiming to shed light into the mysterious world of the Bluntnose Sixgill Shark. One of the largest predators of the deep-sea. Using a submersible to descend depths of 4,500 ft, sixgills were tagged with 2 different devices. Data will be collected on their vertical movements, location, speed, depth and surrounding temperature. Video recordings will also be taken. Findings will be compared with data collected from other scientists researching Bluntnose Sixgill Sharks around world to learn more about this species.

South Africa’s Dwindling White Shark Population

White Shark numbers are continuing to dwindle off South Africa’s Western Cape. With scientists noting a rapid decline in the last 5 years. A few years ago, researchers would expect to see up to 20 White Sharks a day. These days they say they’re lucky to see that many in a year. But where have they all gone and why?

The cause is still not clear. But as top predators, the disappearance of White Sharks has serious implications for the wider ecosystem.

Whilst researchers are questioning where South Africa’s White Sharks have gone. Those on the East Coast of the US are recording more than ever.

Scientists recorded 118 individual White Sharks off Cape Cod, Massachusetts in 2020, up from only 11 in 2013. Sharks fitted with transmitters are detected using under water acoustic receivers. A total of 231 White Sharks have been tagged since 2010. Data collected show shark activity is greater where seal numbers, one of their favoured prey, is highest.

Sharks Almost Went the Way of the Dinosaurs 19 million Years Ago

3 June

Scientists believe they’ve identified a previously unknown major ocean extinction event that happened ~19 million years ago. During which, shark diversity declined by over 70%, and shark numbers by over 90%.

These findings, published in Science were obtained from the presence of shark denticles found in sediment cores taken from the Pacific Ocean seafloor. The cause for this extinction event has not yet been determined.
