Sarquí
Sarquí Key (spanish: Cayo Sarquí), also known as Sarquí Island (or formerly called Garrapatero), is an island in the Caribbean Sea that forms part of the Los Roques Archipelago, belonging to Venezuela.
Administratively, it is part of the Federal Dependencies and until 2011, it was under the administration of the Single Area Authority of Los Roques, the year in which it became part of the Francisco de Miranda Insular Territory.
Geography
Sarquí is located northwest of Espenquí and northeast of Lanquí, and it is fully protected as a Managed Natural Environment Zone within the Los Roques Archipelago National Park.
The island of Sarquí features an elongated and subtly curved morphology in the shape of an arc or crescent, extending predominantly along a north-south orientation axis. Its relief is entirely flat with a very low altitude above sea level, a characteristic geological condition of the reef complexes that comprise the Los Roques archipelago. The western coast stands out for hosting an extensive and continuous beach of fine white sand that borders much of the key's inner shoreline. In contrast, other coastal areas exhibit storm plains composed of accumulated coral fragments and reef rocks exposed directly to tidal action. At its southern tip, the insular structure terminates in a highly dynamic sandy point or isthmus, constantly shaped by local marine currents.
One of the most prominent geographical features of Sarquí's surface is its complex system of brackish and hypersaline internal lagoons located in the central-eastern portion of the territory. The main body of water consists of an indoor lagoon of considerable size that lacks direct surface communication with the open sea. Depending on the season of the year, evaporation levels, and the seasonal proliferation of halophilic microorganisms or sediments, the waters of this central pond undergo notable chromatic variations, transitioning between intense reddish, brown, and olive green tones. Towards the northern sector, the terrain is complemented by additional small water mirrors and flood-prone depressions that enrich the hydrological and ecological dynamics of the island's interior.
Flora and fauna
Sarquí is ideal for activities such as snorkeling and for the observation of fish and sea turtles. The island's vegetation cover is heavily conditioned by salinity and aridity, with a dense carpet of low-growing xerophytic and halophilic vegetation predominating in the interior soil, consisting of beach grasses and creeping plants adapted to sandy substrates. Surrounding the margins of the internal lagoons and in certain portions of the more protected coastline, compact strips of mangroves develop, acting as a vital transition ecosystem.
The shallow and crystalline waters surrounding the key host a remarkable underwater biodiversity, characterized by extensive beds of calcareous sand where colonies of large starfish are common. Furthermore, both the marine coastline and the interior wetlands function as resting, shelter, and feeding areas for various species of Caribbean marine avifauna.
