100-Year-Old Barrel Sponge Sliced In Half at 30 m — We Found What Did It

A 100-year-old barrel sponge — the “Redwood of the Reef” — sliced clean in half at 100 ft (30 m) deep on a remote, enchanting reef. We were on a technical scooter dive when we spotted the damage… then followed a trail of destruction that should not exist. What we discovered was silently sawing through centuries-old coral and sponges. We traced it, confronted the source, and took action to stop it. This is more than just one damaged reef. It’s a wake-up call about how fragile our oceans really are — and what happens when cheap shortcuts replace proper marine practices. Watch until the end to see what the mystery is, what we did and what we learned about the true cost of one careless decision.
