Why does Scuba Diving make you want to Pee?

Anyone who has spent a bit of time on a dive boat will know that they often smell like a dark corner near your local pub – or in other words, they smell like urine. Most divers are too ashamed to say it, but the vast majority of us feel the overwhelming urge to pee […]

Hurricanes, Cyclones & Typhoons

The tropics: the latitudes we associate with paradise. The term conjures up visions of holidays of yore. With those cerulean waters punctuated with occasional forest green land, bikini-clad tanned bodies on sun beds with some type of frozen drink nearby. These are the areas you find hard coral reefs and charismatic megafauna, where liveaboards, snowbirds, […]

Sea Turtle Business

Relatively speaking, there aren’t that many species of marine reptile you are likely to run into on a dive. However, the charisma and love they elicit are enough to fill the ocean. Perhaps none are more beloved than all 7 species of sea turtles. Similar to their terrestrial cousins, they are evolutionary dinosaurs, changing very […]


Freshwater Dolphins

It’s on almost every diver’s bucket list: diving with dolphins. You may have pictures from that trip to South East Asia or Mexico where a pod of dolphins was playing in the dive boat’s wake. Every face in the background is lit up by the sheer magic of cetaceans; no one is immune. So, I […]


Fish ID for Beginners

There are over 28,000 species of fish in waters around the world. Almost 27,000 of these are bony fish – the fish commonly associated with the group. Sharks, skates and rays, or cartilaginous fishes, comprise over 900 species, and jawless fish such as hagfish and lampreys have about 100 species. So, how can you be […]


The Surprising Little Boxfish

I think it’s safe to say that we can all think of examples of fashion or designs coming from nature. But what about a car being inspired by a fish? Which fish species would you guess was the muse? While you go through visions of streamlined tuna, sharks, marlin, and other torpedo shaped fish in […]

Intro to Reef Restoration

It should come as no surprise that coral reefs are in peril. Healthy reefs are disappearing from the planet at an alarming rate. A surprisingly large percentage of food, medicines, coastal protection, and tourism income that the world depends on come directly from these reefs and will disappear equally fast as the reefs themselves. Because […]


Clarity on Chordates

You know those squishy-seeming, Mickey-Mouse-shaped, sort of sponge-looking things you see quite often on reefs? Or those grape-shaped clear balls you sometimes see in the water column, usually stuck together in a chain? They are called ascidians, and they’re also some of our closest cousins, relatively. They, like us belong to a phylum called Chordata, […]


Ocean Deoxygenation

The oceans are changing, and more rapidly than we ever expected. Historically, changes in ecosystems have majorly been slow processes, occurring over hundreds of thousands of years. This would give ample time for the organisms living to adapt to the new challenges and opportunities created in this also evolving ecosystem. However, a few acute points […]
