We came across this hawksbill sea turtle early this morning while cleaning a nesting beach on St. Croix. She had already finished laying her eggs and was making her way back to the water.

We kept our distance and watched her safely return to the Caribbean. Moments like this are a powerful reminder of why protecting nesting beaches—and keeping them free of trash, obstacles, and disturbance—matters so much.

🪱 Meet one of the Caribbean’s most misunderstood reef residents… the Bearded Fireworm.

Most people see the bristles and immediately think danger—and yes, those white bristles can deliver a painful sting if touched. I call it dragon’s breath 🐉 on your skin, But these fascinating marine worms are also an important part of reef ecosystems.

Fireworms help recycle organic material by feeding on dead and decaying organisms, keeping the reef cleaner. Some species may also feed on soft corals or other invertebrates, making them an important part of the complex balance found beneath the surface.

Every dive reminds us that healthy reefs aren’t just about colorful fish and coral—they’re home to hundreds of incredible creatures, each playing a role in the ecosystem.

If you’ve ever been stung by a fireworm—or spotted one while diving or snorkeling—we’d love to hear your story in the comments!

Found these two shrimp in a shallow pool beneath a stormwater outfall on St. Croix, USVI. 50 feet from the shore, no tidal push.

The interesting part is they weren’t at the shoreline or in a mangrove. They were living in a small pooled section of water downstream of the drain where algae and biofilm have built up.

We collected water samples and will be testing bacteria, salinity, pH, and other parameters as part of a reef stressor assessment.

My initial assumption was that marine shrimp couldn’t survive there, but seeing multiple individuals has me second-guessing that.

What do you think is going on?

Freshwater species?
Brackish-water species?
Tidal influence?
Something else?

Today I was out collecting water samples and documenting a shallow fringe reef along the St. Croix shoreline — the kind of habitat most beachgoers walk right past without a second look. What I found packed into a relatively small stretch of rocky shoreline stopped me in my tracks: juvenile fish, everywhere.

Most reef conservation conversations center on offshore coral reefs, and for good reason. But these nearshore fringe reefs are where a lot of reef fish actually start their lives. The shallow water, rock structure, and crevices give juveniles shelter during the most vulnerable stage of their development. Lose these nurseries and you don’t just lose habitat — you cut off the pipeline that replenishes the reef fish populations further offshore.

This is exactly why Caribbean Reef Fish Foundation focuses so much of our work on native species documentation and restoration across the USVI. Fringe reef sits right against the shoreline, which means it takes the first hit from runoff, sediment, and debris before anything else. The fish sheltering there don’t get a warning.

Watching this footage was a good reminder that reef health isn’t just about the dramatic offshore structures. Sometimes the most important habitat is the scrubby, overlooked strip of rock a few feet from the beach.

Have you noticed similar nursery habitats where you live? What kinds of juvenile fish show up in your area?

I captured this short 45-second clip of the waves rolling over the shoreline here in the USVI, and I wanted to share it with anyone who just needs a quiet moment today.

As peaceful as it sounds on the surface, it’s a constant reminder for me of why we do the work we do. I run a local non-profit called the Caribbean Reef Fish Foundation.
While the view from the beach is stunning, our team is entirely focused on what’s happening underwater.

Right now, we are working on the groundwork for a native reef fish nursery to help restore local ecological balance, alongside running community-led efforts to mitigate invasive lionfish. Because our local power grid is notoriously unstable, we are also actively designing our future infrastructure to run on a fully off-grid solar facility.

Marine ecosystem restoration is a massive, uphill battle, but moments like this by the water make every bit of the fieldwork worth it.

Turn the volume up, take a deep breath, and enjoy the sounds of the sea. Would love to hear where you all are listening from today, or what your favorite local ocean sounds are! 🪸🐟

I’ve seen remoras hitching rides on sharks plenty of times, but this is the first time I’ve come across two remoras trying to ride a sea turtle at once. 🐢

Remoras use a specialized suction disc on top of their heads to attach to larger animals, saving energy while getting a free ride through the reef.

This turtle didn’t just pick up one passenger today… it became a full-blown taxi service. 😆

Nature never runs out of surprises beneath the surface.

Did you know?

In the 1970s, projects like the Osborne Reef off Florida dumped millions of tires into the ocean with good intentions, believing they would create thriving artificial reefs.

Instead, many of those tires broke loose, damaged natural reefs, and became one of the most infamous marine restoration failures in history.

Today, tires are still finding their way into Caribbean waters-but not as part of restoration projects. They are often illegally dumped as waste, especially in the USVI.

Marine life will try to adapt and find shelter anywhere it can.

But tires don't belong on our reefs. They can smother habitat, shift during storms, trap wildlife, and introduce pollutants into the marine environment.

This #ReefAwarenessDay, we're reminding everyone that protecting our reefs doesn't always require a grand gesture.

Every piece of trash removed, every responsible disposal decision, and every cleanup effort helps.

Small actions add up.

Let's keep tires on the road and out of the ocean.

Our team was out tracking stressors and removing marine debris when we caught this interaction on camera.

If you look closely, the little goby swims straight up to a wedge of discarded white plastic tangled with old leaves.
He stops dead in his tracks at the artificial barrier.

He thought for a second humm 🤔 “what’s this” then you can see him navigating completely out of his way just to skirt around it.

It’s easy to think about ocean trash solely impacting large pelagic animals, but plastic pollution hits the micro-habitats just as hard. For a small tidepool fish, a single piece of litter is an entire mountain blocking their territory and ruining their natural camouflage against predators.

We cleared the plastic out of the pool right after filming this, but seeing him forced to navigate a human mess in his own home was a stark reminder of why preservation matters at every scale.

Have you ever witnessed marine life directly interacting with or navigating around trash on your cleanups?

Watch how this plays out: The Bar Jack is cruising along the seagrass first. Suddenly, the octopus uses jet-propulsion to rocket forward, catches up to the jack, and they sprint side-by-side like they're racing. Then, the octopus abruptly drops the anchors and stops dead in its tracks.

While it looks like a friendly swim, you are looking at a highly calculated underwater crime syndicate known as nuclear hunting.

They team up based entirely on mutual greed. The Bar Jack shadows the octopus because it knows the octo is about to use its arms to flush out crabs and small fish from the grass. That sudden stop at the end? That's the climax—the octopus halts to dive into a patch of grass or a crevice, while the Jack hovers right on top to intercept anything that bolts.

If the fish gets lazy or tries to steal too much, studies have shown the octopus will literally reach out and punch them to keep them in line.

Have any of you caught an octopus hunting with a fish entourage like this before? What species were they teaming up with?
