We asked our contributors what their favorite unusual critter dive was and they answered with stories and photos of weird and wonderful creatures, big and small, giving first-hand accounts of their often bizarre behaviors under the waves.

Indonesia's Lembeh Strait: Relax & Enjoy Muck Diving & More

Harlequin shrimp on sponge, Lembeh Strait, Indonesia.

For underwater photographers, when we talk about Lembeh Strait in Indonesia, lots of macro subjects and small critters come to mind. “Muck diving,” which involves diving in muddy areas where lots of small animals can be found, is actually the main business of the localresorts and dive centres. But as you will find out in this article, there are lots of other things to see here too.

California's Channel Islands: Kelp Diving on the US West Coast

Due to their unique position relative to the eastern Pacific current, or the California Current, the Channel Islands off California’s coast receive an ideal amount of nutrients and water circulation for optimum growth of California giant kelp. This colonial algae forms forests over the rocky reefs and walls surrounding the islands, and act as one of the world’s most productive marine ecosystems.

The Florida Panhandle Shipwreck Trail

While Florida’s eastern coast certainly offers countless popular wreck dives, the Panhandle is an often-overlooked gem. The Florida Panhandle Shipwreck Trail provides an enjoyable mechanism for divers to experience the history and heritage the Gulf of Mexico has to offer within the realm of wreck diving.

Surviving Lockdown

For most of us in lockdown during the coronavirus pandemic, being away from diving in itself is enough to cause withdrawal symptoms. Sometimes, factors such as work, weather and lifestyle can mean that we take longish breaks, although I do not think anyone has taken such a long break before—certainly not one that left no choice and one that required significant lifestyle changes and restrictions.

My Favorite Wide-Angle Dive: Contributors' Picks

We asked our contributors what their favorite wide-angle dive was and they came back with stories and photos from some of the most unique and exhilarating dive sites on earth, many of them relaying interactions with large marine life from Steller sea lions in Kamchatka and giant manta rays in Komodo to tiger sharks in the Bahamas and humpback whales in the Dominican Republic.

Bracenet

I first reported on 'Bracenet' in February 2019, because it was the only environmental bracelet I had come across up to that date, that has clear provenance. How it is made, and where the profits go!

Dying coral reefs saved by automation

Healthy coral reefs provide food and a home to about 25% of all the world’s marine creatures, sustain an estimated 6 million fishermen, provide coastal protection by reducing the impact of waves and support local tourist economies. But corals worldwide are under threat. Mass bleaching is rapidly threatening the world’s coral reefs, with an estimated 50% already lost and 90% projected by mid-century.

Karlsruhe was a light cruiser which participated in Operation Weserübung, the invasion of Norway in 1940.

German WWII cruiser found between Norway and Denmark

Statnett, the Norwegian state-owned power grid operator, made the astounding discovery of the lost Karlsruhe cruiser around 488 meters (1,600 feet) below sea level off the Southern coast of Norway, some 13 nautical miles from the port of Kristiansand. Signs of wreckage were first detected three years ago during inspection work when sonar detected a shipwreck only 15 meters from an undersea power cable between Norway and Denmark.

Are dangerous and meaningless records being spurred on by recognition by Guinness Book of Records?

Depth record called into question

In September 2014, Egyptian national and technical diver Ahmed Gabr performed a deep dive off Dahab in the Egyptian Red Sea under the auspices and observation of adjudicators from The Guinness Book of Records. After the dive, Gabr was acknowledged for having reached the record depth of 332m, surpassing South African Nuno Gomes who made it to 318m in 2005, also off Dahab.

The crown-of-thorns starfish can sometimes be hard to spot using traditional survey methods.

New test to detect crown-of-thorns starfish

Outbreaks of crown-of-thorns starfish (CoTS) are bad news for coral reefs, so it is essential that they are detected and dealt with as soon as possible.

But detecting an outbreak in its early stages is not easy. What’s more, they sometimes hide under coral plates, while the younger ones can be as small as just a few millimetres.

To counter this, the researchers at the Australian Institute of Marine Science (AIMS) developed a new test to detect the presence of the starfish on coral reefs.
