Klein Bonaire Reef

Kralendijk · Caribbean Netherlands · Bonaire

Klein Bonaire sits in the Caribbean Sea like a low green disc, an uninhabited island of about six square kilometres lying roughly eight hundred metres off the western coast of Bonaire. The island has no buildings, no roads, no electricity, and no permanent human presence. What it has is reef. A continuous fringing reef encircles the island, its coral coverage extending from the waterline to depths beyond recreational limits, creating what marine scientists consistently identify as one of the healthiest reef systems remaining in the Caribbean basin. I crossed from Kralendijk on a calm March morning, the boat cutting through water so clear that the bottom was visible throughout the ten-minute crossing. Klein Bonaire's shoreline appeared as a strip of white sand backed by low scrub, its modesty above water giving no hint of the extravagance below. We moored at a site on the island's southwestern side where the wall was reputed to be at its most dramatic. The reef began in knee-deep water. Standing at the waterline, I could see coral formations extending outward in an unbroken carpet of colour and texture. The shallow terrace, from zero to eight metres, was dominated by elkhorn coral that had survived where equivalent colonies elsewhere in the Caribbean had been devastated by disease. The elkhorn's antler-shaped branches created a three-dimensional habitat that hosted clouds of blue chromis and juvenile wrasses, their tiny bodies darting through the coral architecture with the frenetic energy of youth. The drop-off began at ten metres, the reef terrace ending abruptly at a wall that descended vertically into blue infinity. The wall face was a gallery of coral diversity. Sheet corals extended from the rock face like shelves, their flat surfaces providing platforms for resting fish and feeding nudibranchs. Wire corals spiralled outward from the wall in tight coils, their whip-like forms swaying in the gentle current. Tube sponges in purple, red, and yellow dotted the wall at every depth, their openings serving as chimneys for the water filtration that is their life's work.
