Contrary to long-standing beliefs, recent research has revealed that grey reef sharks can rest, overturning the assumption that they must constantly swim to breathe. This groundbreaking discovery, made in the Seychelles, offers new insights into the physiology and behaviour of these marine predators. 

Researchers conducted trials using SMART drumlines in New South Wales, Australia, to catch and release sharks, particularly White Sharks. The study aimed to quantify the short-term post-release movements and the longer-term fate of these sharks.

Sharks were caught using SMART drumlines deployed about 500 meters from shore. Once captured, they were quickly secured to a research vessel, minimising potential injuries. The sharks were tagged with satellite-linked radio transmitting tags and acoustic transmitters to monitor their movements post-release.

Sharks are known for their remarkable ability to heal quickly from wounds. The mucus layer on their skin plays a crucial role in this process. Recent research has uncovered that the mucus layer on shark skin possesses properties that could be beneficial in medical applications, particularly in wound care.

During the DEMA Show in New Orleans, I encountered a dive industry colleague who appeared quite distressed. He had just discovered that a Formula One race was scheduled concurrently with the next DEMA Show in Las Vegas. His concern was that securing a hotel would be impossible, as he believed everything was already booked. At that moment, I was somewhat sceptical of his concern.
