Tensions High For Blacktip Island’s Coral Bonsai Show

Security is tight above and below the water at Pinnacle Reef this week for Saturday’s Blacktip Island Coraliculture Society’s quinquennial Coral Bonsai Show.

“Last time around there was all sorts of skullduggery to make competitors’ bonsais look bad for the judging,” society president Rupert Basslet said. “Rascals silted the coral, toppled sculptures, and there was one instance of an underwater heater being placed next to a bonsai to make it bleach the day before the show.

“The coral bonsai world can be incredibly vicious,” Basslet said. “We put our collective foot down this year. We have divers with spears patrolling underwater, and spotters on shore to make sure no one slips in unnoticed.”

The show is staged every five years to allow the coral sculptures to regrow after pruning.

“Coral grows so slow you have to wait ages post-prune to see the full effect,” said show chair Chuck DelKorn. “We tried to have the show annually, but the results were not esthetically pleasing. Lots of bare limestone where the coral polyps hadn’t grown back over.

“It takes decades to get one looking right,” DelKorn said. “Most of these bonsais have been passed down from generation to generation.”

Each bonsai master has their own idiosyncratic mix of preferred tools for coral sculpting.

“Coral’s fragile. Keeping a bonsai small and trim, one tiny slip can be irreparable,” Basslet said. “I use a child’s tack hammer and set of jeweler’s screwdrivers. All it takes is a tap here, a chip there. And sometimes years go by without my doing anything to my bonsai.

“Any hard coral is eligible, but the branching species seem to catch the judges’ eyes,” Basslet said. “Though Alison Diesel won the last show with her miniature pillar coral. I think it was the extended polyps waving in the current that put her over the top.”

On shore, local businesses are bracing for the influx of coral bonsai enthusiasts the event brings to Blacktip Island.

“These fans are hard core, and the reef’s cordoned off during the judging,” said Christina Mojarra, manger of the Tail Spinner Lounge, overlooking Pinnacle Reef. “We installed underwater video cameras and doubled our number of TVs so fans can watch at the bar. Parking’s tight, so we’ll have valet parking, and a shuttle van for guests at the island’s resorts.

“They award the Golden Polyp trophy here in the dining room,” Mojarra said. “So we’re letting Dermott Bottoms and James Conlee drink free in exchange for to maintaining order. Last bonsai show the runners-up caused such a ruckus, it was a week before we could reopen.”

Singing Coral Heads Discovered on Blacktip Island

Blacktip Island researchers this week documented coral heads on the Caribbean island’s Jawfish Reef interacting with other corals via harmonic resonance.

“There’d been tall tales from scuba divers about singing coral,” Tiperon University-Blacktip professor Ernesto Mojarra said. “On a hunch, we installed one of our new Broadband Datalogging Sound/Vibe Monitoring arrays on the reef. The BDSM tests showed the staghorn polyps flagellate to create high-frequency vibrations.

“It’s more of a high-pitched hum than actual melody,” Mojarra said. “Like Tuvan throat singing, but in the 16740 hertz range. Near as we can tell, that lets polyps communicate coral-to-coral. It also explains why more people hear the tones as the staghorn recovers from near extinction.”

The discovery settles a debate that’s raged among Blacktip’s divers for years.

“There’s always that annoying whine at Jawfish” Eagle Ray Divers divemaster Marina DeLow said. “Like The Chipmunks singing ‘Good Vibrations.’ I chalked it up to doubling up on Sudafed, or vodka hangovers. Now we know better.”

Some experts, however, dispute the finding.

“This is textbook wish fulfillment, fueled by alcohol and who knows what else,” Island Psychological Association president Sigmund Skinner said. “Every scuba hippy wants to anthropomorphize the reef. They want to believe coral flagellates to communicate, and hey! What do you know? They discover coral flagellates. And sings while it does it!”

Local business owners, however, embraced the discovery.

“If coral can communicate with other coral, it stands to reason it can communicate with other organisms, even humans” said Elena Havens, owner of the Blacktip Haven resort. “Elephants communicate over vast distances with ultra-low frequency sounds. This is really no different.

“We’ve started underwater meditation sessions on the reef,” Havens said. “The effects have been stunning. It’s like our guests have become one big polyp colony.”

Researchers, meanwhile, are scrambling to catalogue the coral sounds.

“Ernesto brought us in to decipher the individual tones and tone combinations,” TU-B linguistics department chair Porgy Chomsky said. “We’re testing whether this is simply a species-specific vocabulary, or if we’re dealing with a pancorallic semiotic. It’s potentially ground breaking. Staghorn coral’s the Chatty Kathy of the reef.”

TU-B’s Mojarra concurred.

“If these harmonics are fueling coral growth, it could be key to restoring coral populations worldwide,” Mojarra said. “We have plans to regenerate individual coral heads with recorded music. And a crack team of marine geologists is working up plans for underwater coral topiary.”
