Narwhals, notwithstanding their unicorn-like tusks, are a mysterious species. They live in distant Arctic regions and hunt as deep as 1,000 meters down.
They orient themselves using echolocation, making clicking sounds to explore their surroundings. When they hunt, the clicking sounds turn into buzzing sounds as the interval times shorten.
In the pre-drone days, researchers relied on their observations of the orcas when they surfaced, and this was understandably limited.
“Until now, research on killer whale social networks has relied on seeing the whales when they surface, and recording which whales are together," said lead author Michael Weiss, of the University of Exeter.
"Looking down into the water from a drone allowed us to see details such as contact between individual whales," he added.
We received hundreds of nominations and left it up to a varied panel of loyal staff to sift through the entries. All inspired, many amazed and some brought tears. What is clear is that divers are awesome, and it came as no surprise that within the international underwater community there were so many selfless, empathetic heroes.
Our panel have made the final choice for the 8th liveaboard prize, this time for a trip of a lifetime in The Maldives, Nominated by his cousin, Alex Chan, this is his story:
Scientists have discovered that clownfish living closer to shore die sooner than their counterparts found farther offshore due to the difference in the amount of artificial-light exposure.
The more artificial light they were exposed to, the higher the mortality rate.
The study focused on the reefs around Moorea in French Polynesia. It involved exposing 42 juvenile clownfish to either artificial light at night (ALAN) or natural light (meaning, moonlight!) in the lagoon. Each of the 42 territories had a magnificent sea anemone.

A new population of pygmy blue whales has been discovered in the Indian Ocean, thanks to underwater nuclear bomb detectors that recorded their whale songs.
The research team, led by the University of New South Wales (UNSW), had been studying data from the Comprehensive Nuclear-Test-Ban Treaty Organization (CTBTO) which monitors international nuclear bomb testing, when an unusually strong signal caught their attention.
Dr. Moon is a professor of anesthesiology at Duke University and the medical director of the Duke Center for Hyperbaric Medicine and Environmental Physiology. He is also a former medical director of DAN.
Throughout his 40-year career in dive medicine and research, Dr. Moon has sought to gain a better understanding of cardiorespiratory function on the human body when subjected to environmental conditions such as being deep underwater or at high altitude.
