Despite breaking the rules of traditional ocean camouflage (where a white belly helps a ray blend into the bright surface when viewed from below), he is thriving, healthy, and completely accepted by his fellow rays. In fact, most times he is spotted, he is actively participating in courtship trains with standard-colored mantas. He is an absolute, one-of-a-kind marvel of nature!

A special treat for you: Inspector Clouseau!

This is "Inspector Clouseau," the world's only known pink manta ray. He is an 11-foot (3.4-meter) male reef manta ray who lives around Lady Elliot Island at the southern tip of Australia's Great Barrier Reef. He was first discovered in 2015 and was aptly named after the bumbling detective in the Pink Panther films.

When a diver is completely calm and breathing steadily, their body emits a steady, rhythmic bio-electric frequency. Manta rays can instantly sense this. Because they have massive brains relative to their body size, they are profoundly analytical. When they approach a diver closely and hover, they are combining their vision with their electroreceptors to create a complete "sensory map" of you.

Why Manta Rays Look at Us Intently

While bottom-dwelling stingrays use this sense primarily like radar to find crabs hidden deep under the sand, pelagic (open-ocean) giants like manta rays use it for complex navigation, communication, and social curiosity.

@briangweberphotography Definitely, but a few days later I did have some battery left when a Giant Manta Ray gracefully passed by. It was surprisingly fast. I could not keep up at all. #MantaRays #Bonaire

The K2 dive site off Gili Banta is highly recommended for manta ray lovers. Whether they are gliding gracefully or hovering over coral heads, these giants are a sight to behold.

World's largest rays may be diving to extreme depths to build mental maps of vast oceans https://phys.org/news/2025-10-world-largest-rays-extreme-depths.html

"#MantaRays are capable of diving to depths greater than 1,200 m, far deeper than previously thought... they usually initiated an extreme dive within a day after moving off the continental shelf and into deeper waters... they may use cues such as changes in magnetic field, or sample changes in oxygen, temperature, light levels... to build a mental map that helps them navigate"

Scientists Finally Make Heads of Giant #Stingray Tails
The long structures seen in #mantarays and their relatives function as an early warning system, rather than a defensive weapon.
The team discovered that the stiff tissue of a cownose ray’s tail was pockmarked with holes. The 3-D scans revealed that these holes were linked to the #fish’s #lateralline canal, a system of sensory organs found in fish and amphibians.

#Mantarays inspire faster swimming robots and better water filters
With fins that borrow their shape and motion from mantas, a soft robot created by a team of researchers at NC State and Univ of Virginia improves on a previous model by reaching speeds of 6.8 body lengths per second, nearly double what its predecessor was capable of. Another research team at MIT used the gills of these creatures, which filter for plankton, to improve commercial water filtration systems.

Episode one hundred and fifty-one is up now! Today's song is Manta Rays by Ludo.

I discuss the unique and compelling imagery Volpe employs in his lyrics, and how this song contrasts with much of the band's sillier ouvre.

Part of last night's dream included a rodeo in Oklahoma. They set up a giant horse trough so they could race manta rays. They also set up a massive pyrotechnics platform for the start of the race.

The image is staying with me longer than most dream images, but the thing that my brain won't let go of is the certainty that I've never had to write the word 'trough' before, and that I don't like the way it's spelled at all.

Most species of manta and devil rays (genus Mobula) are endangered, yet industrial purse seine fishing vessels unintentionally catch about 13,000 each year while hunting tuna, according to one scientific estimate.

New regulations, handling techniques and equipment aim to reduce this number.

"Manta ray populations are thriving in Indonesia’s Raja Ampat archipelago, a new population assessment shows, highlighting the importance of marine protected areas to the species’ conservation.

The study showed that reef manta ray (Mobula alfredi) populations saw up to 10.7% compound annual increase from 2009-2019 in the region, even as global ray and shark populations undergo a sweeping decline."

Read the story from Cassie Freund.

Nautilus Explorer – Revillagigedo Archipelago (Socorro)

I joined the team on the Nautilus Explorer for a dive trip to the Revillagigedo Archipelago off the coast of Mexico. The Revillagigedo Archipelago is also referred as the Socorro Islands. Linguistically challenge English speakers like to call the island chain “Socorro” which is the most popular island.

The Revillagigedo Archipelago is a collection of volcanic islands in the Pacific Ocean. The islands are located about 285 miles southwest of Cabo San Lucas, Mexico. It takes about 22 hours by liveaboard to travel to the islands.

The Archipelago consists of four islands – San Benedicto, Socorro, Roca Partida and Clarión. In 2016, the Revillagigedo Archipelago was designated as Unesco World Heritage Site and in 2017 Mexico declared it to be a marine reserve and national park.

Scuba divers are attracted to the region because of the resident Pacific Mantas, Bait Balls, Whales, Dolphins and several species of Sharks.

And since it take about a day by liveaboard to reach the islands. Scuba diving the region is quite unique and thrilling.

Before heading to Socorro

In addition to owning a fleet of  liveaboards designed for scuba divers, Nautilus Dive Adventures also owns a local dive shop located in the Cabo San Lucas marina. See Creatures offers a free check out dive before you board the liveaboard and they also provide local diving for a reasonable price.

I arrived to Cabo a few days before the Nautilus Explorer liveaboard departed for Socorro. So, I was able to sample a bit of local diving. We first headed to Cabo Pulmo National Park. Cabo Pulmo is about a 2-hour car ride north from Cabo San Lucas. See Creature picked up divers at our hotel and drove us to the dive boat. They have a partnership with a regional dive shop and that shop provided boat, guide, tanks and lunch. Scuba divers like to visit Cabo Pulmo due to the amount of schooling fish and Bull Sharks.

The next day, we took about an hour boat ride from the Cabo San Lucas Marina to dive Gordo Banks. Scuba divers are attracted to Gordo Banks due the opportunity to see schooling Hammerhead Sharks. These are deep dive at the edge of recreational limits. So, See Creatures requires divers to book one local dive before they venture out to Gordo Banks. The dives in Cabo Pulmo met the requirement.

Unfortunately, on both dive sites visibility was extremely poor due to an incoming storm. So, we did not see any Bull or Hammerhead sharks. Since the waters are rich in plankton, we did see a lot of Jellyfish on both dives.

I’ll just have to go back for more diving and tableside guacamole from Captain Tony’s Bar & Grill. They make it under 3 minutes!

The Nautilus Explorer offers a free check-out dive via See Creatures for all liveaboard divers. This provides divers the opportunity to check their equipment and dial-in there weight for diving in colder water and thicker wetsuits. During this trip, I dived my 5mm Tux and my ordinary 7mm wetsuits. Water temperature varied in each island in the Revillagigedo Archipelago.  Divers just need one wetsuit, I just like diving my tuxedo wetsuit and I don’t have to worry about airline weight requirements (at the moment).

Host Hotel

Most divers using the Nautilus Explorer and other liveaboards arrive a day before the liveaboard departs and conveniently lodge at the Tesoro Los Cabos Hotel.  The local dive shop, See Creatures is also located in the hotel, which makes transition from local diving to the liveaboard extremely effortless and comfortable.

It is recommend to arrive a day earlier mitigate any issues with baggage delays, forgotten personal items, and/or scuba equipment issues.

Nautilus Explorer

The Nautilus Explorer was launched in 2000. It is about 132 feet long, 13 en suite staterooms and suites. The ship holds 25 divers and crew of 10. Rare to liveaboards, the ship offers internet access at a small cost. However, connection is not guaranteed being so remote. But you can at minimum check email and do light web browsing if necessary. Overall, the liveaboard is well maintained and provides nearly everything a scuba diver will require for a week of diving.

Note: I traveled during Covid restrictions so normal service on board was modified. For example, only a limited amount of passengers were allow in enclosed areas of the ship. So, divers were sorted into two groups for dinning, which coordinated with boat dives. Also, all passengers were required to take a 2 PCR tests. One PCR test was taken before we departed from our home testing site and the second was taken several hours before we boarded the liveaboard. The Nautilus offer divers a full credit if a diver tested positive in Mexico. This was a great policy because many other operating liveaboards around the world do not offer this policy and divers would have to rely on personal travel insurance.

Final Thoughts

All though weather conditions were not great and visibility was low, I enjoyed the dive trip. The crew was fantastic and the food was great! I’ll have to just try again for better visibility! And I would definitely join the Nautilus team for another dive trip.

All of the underwater images were captured on a Panasonic GH5 in a Nauticam underwater housing with a Panasonic Lumix 14-42 lens.
