"Slow" marine animals show their secret life under high magnification. Corals and sponges are very mobile creatures, but their motion is only detectable at different time scales compared to ours and requires time lapses to be seen. These animals build coral reefs and play crucial roles in the biosphere, yet we know almost nothing about their daily lives.

This is a highlight reel mostly from two weeks of diving in southern Sudan aboard the Don Questo live-aboard, with supplementary footage from Saudi Arabia. The central Red Sea (southern Sudan in particular) is a truly fantastic place, home to an array of incredible sharks species, majestic manta rays, massive groupers, curious jacks, schools of barracudas and more. This video was created to showcase the incredible beauty of the region and, more importantly, to inspire and convince viewers that this largely unknown, unfished, and unexplored place is well worth preserving.
Alex Kattan is a masters student in marine science at the King Abdullah University of Science and Technology (KAUST) in Saudi Arabia. He loves the ocean and all its inhabitants, with a particular fascination with tropical coral reefs. He enjoys sharing this passion with others through education, outreach, film and social media.

There’s World Turtle Day (May 23) then there’s World SEA Turtle Day, which is today! Why is June 16th World Sea Turtle Day? It is the birthday of Dr. Archie Carr who is widely known as “the father of sea turtle biology.” Dr. Carr focused his entire career on sea turtle research and conservation. According to The Sea Turtle Conservancy:
Archie Carr was a great biologist. His early descriptive studies of turtles set the standard of quality in the field of natural history. Later on, as he focused on sea turtles, he moved toward ecology and behavior, although his work always retained a taxonomic and evolutionary perspective. For decades the National Science Foundation (and the Sea Turtle Conservancy and the Office of Naval Research) supported his research at Tortuguero, enabling him to mount one of the longest lasting and most intensive studies of an animal population that has ever been done. To date, more than 35,000 adult female green turtles have been tagged at the research station at Tortuguero. From this effort have come papers by Archie Carr, his students, and other investigators on orientation, migration, nesting behavior, nest physiology, sensory physiology, nutrition, demography, and other subjects. Almost all of the studies have significance for conservation — Archie Carr was a conservation biologist long before the field was recognized.
Of the seven sea turtle species, five are listed on the IUCN Red List as either vulnerable, endangered, or cirtically endangered. They are: leatherbacks (vulnerable), loggerheads (endangered), hawksbills (critically endangered), green sea turtles (endangered), Kemp’s Ridley (critically endangered), Olive Ridley (vulnerable), and flatback sea turtles (data deficient). What can you do to protect sea turtles?
- At night, keep bright lights off the beach to encourage sea turtles to nest and to ensure hatchlings can find their way to the sea.
- Keep beaches trash free to avoid turtles mistaking it for food or getting caught in plastic loops. Single use plastic bags are often mistaken by sea turtles for their favorite food, jellyfish. Consumption can cause them to suffocate.
- Join a coastal conservation effort working to protect sea turtle nests from predators.
- Of course you can always donate to MarineBio or join the MarineBio Conservation Society to help us share species information and raise awareness about the plight of endangered sea turtles. Whether you can spare $5 or $50, it will help us continue bringing the world a vast source of information on all things ocean.
A research crew from Japan’s National Science Museum have managed to capture on film for the first time a giant squid (Architeuthis) in its deep sea natural habitat. Working with Japanese public broadcaster NHK and the US Discovery Channel, the researchers found the massive invertebrate at a depth of a depth of 630 metres as the animal was holding on to bait swimming against the current in the depths. The footage was filmed in the Pacific Ocean near the Ogasawara Islands, 1000 km south of Japan, an area where two previous sightings in 2006 and 2012, have been reported. Continue reading
The following outstanding 2 hour video shows the amazing biodiversity of the marine life in the Andaman Sea (in the northeast Indian Ocean). Produced by Nick Hope at Bubble Vision, he again amazes us while introducing us to many rarely seen marine species the way they should be met, in their home under the sea.
“In the deepest, darkest parts of the oceans are ecosystems with more diversity than a tropical rainforest. Taking us on a voyage into the ocean — from the deepest trenches to the remains of Titanic — marine biologist David Gallo explores the wonder and beauty of marine life.

More about David Gallo:
The video above is of a sea cucumber feeding. Within the ocean, organisms have adapted many different methods of gathering food. It’s not as easy to find food in water as on land, even within the same species there can be many different methods, just look at fish! You have gigantic whale sharks that filter feed on tiny planktonic creatures, to deep sea angler fish that use a flashing lure that brings food close enough to grab or even the awesome gulper eel that’s stomach is bigger than the body so it can eat a meal of any size.

So I should probably begin with part 1…. Back in 1960, January 23rd to be precise, the first ever deep submersible dive occurred by two oceanographers, Don Walsh and Jacques Picard. Using the Bathyscaphe Trieste (above) they reached a depth of 10,911 m (35,797 ft) at the Challenger Deep section of the Mariana Trench, the deepest part of the ocean (11 km or about 7 miles deep). This so far, is still the only time this depth has ever been reached in the ocean by humans with it taking the Trieste five hours to reach the bottom and only being allowed 20 minutes at this depth due to the constraints of technology at the time.
