“Waimanu – a Hawaiian Monk seal – was seen at the Manta Ray Night Dive a few times over the past few weeks, but always on the dark outskirts. Last weekend, we captured NEVER-BEFORE-SEEN footage of Waimanu swimming through the dive site while the Manta Rays were feeding on plankton.
The Hawaiian Monk seal is considered a critically endangered animal with a population of approximately 1100. Most Hawaiian Monk Seals live around the Northwestern Hawaiian Islands; only a few populate the main Hawaiian Islands. Three monk seals inhabit the Big Island and Waimanu – the only female – is currently pregnant.”
“Here’s a little something to start off your year underwater: frogfish, cuttlefish, pipe horse, spider crab, mantis shrimp and more! The water is sooooo coooooold! But that’s what these critters seem to like! Special thanks to Marcie Melton for spotting the beautiful juvenile hairy frogfish!

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.
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.

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.

Alvin, the legendary research sub built by WHOI in 1964 and who allowed researchers to discover hydrothermal vent communities in 1977, is getting a major overhaul. Alvin allows researchers to conduct biological, chemical, geochemical, geological and geophysical studies while making 150 to 200 dives a year. Currently it can only reach depths of 4,500 meters (2.8 miles) and was planned for retirement until recently…
