stands of mangroves, which alternate between practically<br />

impenetrable and more open areas. A typical feature of<br />

the entire area is a confusing labyrinth of natural channels<br />

through which water streams in the rhythm of the<br />

tides. The predominantly bushy vegetation on the long,<br />

narrow islands can best be described as a collection of<br />

different coastal plants.<br />

FIRST IMPRESSIONS<br />

Our speedboat roars out across the gulf for about 50<br />

miles (80 km) from Júcaro to reach the broad passage between<br />

the two cayos of Caballones and Anclitas. Here the<br />

hotel ship La Tortuga, the only permanent place to stay<br />

in the Jardines de la Reina, lies at anchor in a sheltered<br />

bay surrounded by mangrove thickets. The 93-mile-long<br />

(150-km) archipelago is uninhabited, has been protected<br />

since 1997, and now has the status of a national park.<br />

There is no commercial fishing here; only fly-fishing by<br />

licensed anglers is permitted. No more than 400 divers<br />

per year are allowed to explore this unspoiled underwater<br />

world, and each is limited to one week of fishing.<br />

There are attractive dive sites all along the side facing<br />

the Caribbean. The bottom profile is significantly determined<br />

by the Yucatan Basin. On nautical charts the underwater<br />

contour lines lie close together, showing how<br />

steeply the bottom drops away. The 1.2-mile (2,000-m)<br />

isobath lies not far from the cayos. The exposed position<br />

of the Jardines de la Reina has had a considerable influence<br />

on the development of the imposing fringing reefs<br />

and their rich fauna, which includes numerous openwater<br />

species as well.<br />

Before diving, we wanted to look around in the shallows<br />

of the extensive reef top. We quickly arrived at one<br />

of the sites suitable for snorkeling. Here the rays of the<br />

sun, broken up by the waves, danced brightly through<br />

the clear water and created an ever-changing pattern on<br />

the limestone plateau, which lay barely more than 16<br />

This young<br />

colony of Knobby<br />

Cactus Coral<br />

(Mycetophyllia<br />

aliciae) exhibits<br />

larger specimens<br />

form more or less<br />

radially oriented<br />

ridges.<br />

feet (5 m) below us and was rather bare, swept clean by<br />

the sometimes rough seas. Above this solid base towered<br />

Elkhorn Corals (Acropora palmata) of such monumental<br />

stature that the endless play of sunlight looked like<br />

flickering stage lighting amid surreal scenery. Because<br />

this coral species requires constant water movement and<br />

hence grows only in the shallows, its spreading branches<br />

are sometimes snapped off during violent storms. We<br />

saw the results of this in another, rather battered site,<br />

where only short stumps of huge branches remained after<br />

a tornado had swept through.<br />

The sometimes immense power of the sea is also the<br />

reason we found mainly stony corals (for example Faviidae,<br />

Poritidae) of compact growth. Shoals of grunts (for<br />

example the French Grunt, Haemulon flavolineatum) and<br />

snappers (for example the Schoolmaster Snapper, Lutjanus<br />

apodus) inhabited the panorama, even though the<br />

fishes liked to retire among or beneath<br />

the corals. The Great Barracuda (Sphyraena<br />

barracuda) is one of the top dogs<br />

in this terrain. These solitary predators<br />

command a lot of respect; they<br />

often followed us and fixed us with<br />

glassy stares. But if we tried to get close<br />

enough to photograph them, they immediately<br />

beat a retreat.<br />

BIZARRE UNDERWATER<br />

LANDSCAPES<br />

The Caribbean harbors the greatest<br />

wealth of species of reef-building corals<br />

in the Atlantic Ocean. But the edifices<br />

The coloration of the Lettuce Sea Slug<br />

(Elysia crispata), which grows up to 2.25<br />

inches (6 cm) long, varies considerably.<br />
