Malpelo Fauna and Flora Sanctuary: A Marine Biodiversity Haven
The Malpelo Fauna and Flora Sanctuary, inscribed as a UNESCO World Heritage Site in 2006, is a significant marine protected area located approximately 506 kilometers off the coast of Colombia. Encompassing Malpelo Island and its surrounding marine environment spanning 857,150 hectares, this sanctuary serves as a vital habitat for numerous globally threatened marine species and boasts one of the most diverse marine ecosystems in the Eastern Tropical Pacific.
More to come…UNESCO Description of the World Heritage Site
Located some 506 km off the coast of Colombia, the site includes Malpelo island (350 ha) and the surrounding marine environment (857,150 ha). This vast marine park, the largest no-fishing zone in the Eastern Tropical Pacific, provides a critical habitat for internationally threatened marine species, and is a major source of nutrients resulting in large aggregations of marine biodiversity. It is in particular a ‘reservoir' for sharks, giant grouper and billfish and is one of the few places in the world where sightings of the short-nosed ragged-toothed shark, a deepwater shark, have been confirmed. Widely recognized as one of the top diving sites in the world, due to the presence of steep walls and caves of outstanding natural beauty, these deep waters support important populations of large predators and pelagic species (e.g. aggregations of over 200 hammerhead sharks and over 1,000 silky sharks, whale sharks and tuna have been recorded) in an undisturbed environment where they maintain natural behavioural patterns.
UNESCO Justification of the World Heritage Site
Criterion (vii): The pristine underwater environment of Malpelo Fauna and Flora Sanctuary featuring dramatic cliffs, rock formations, caves and tunnels, as well as abundant and diverse marine life is of striking natural beauty. The major aggregations of the full range of large top predators are an increasingly rare sight in the World's overfished seas. The geographically extraordinary position at the meeting point of several marine currents, the varied underwater mountain seascape and the excellent state of conservation combine to make the property a World Class ocean oasis – and an exhilarating experience for divers.
Criterion (ix): Due to its remote location and as the largest no-fishing zone in the Eastern Tropical Pacific, Malpelo Fauna and Flora Sanctuary supports unaltered ecosystems free of major acute threats. The confluence of several marine currents turns the property into an unusual geographical spot with a complex and diverse array of habitats and species. The three major marine communities surrounding Malpelo Island can be distinguished as belonging to the vertical habitats, the coral reefs and the pelagic. Large top predators continue to fulfil their ecological roles and behaviour patterns continue undisturbed, providing unique opportunities for research. The evolutionary processes associated with the extreme isolation, the convergence of several ocean currents and related nutrient regimes and the geological formations are of great ecological importance and scientific interest. Free of alien invasive species, Malpelo Island and the surrounding waters are not only a conservation gem on its own but contribute to the maintenance, dispersal and replenishment of benthic larvae of corals, fish and mollusks and other marine life in the broader Eastern Tropical Pacific. As the wider region is under increasing pressure from overfishing and other threats, the property is thus of enormous conservation and indeed economic importance well beyond its boundaries.
Encyclopedia Record: Malpelo Island
Malpelo is an oceanic island in the eastern Pacific Ocean, about 500 km (310 mi) west of the Colombian mainland with a military post defended by the Colombian Armed Forces. It consists of a sheer and barren rock with three high peaks, the highest being the 300 m (980 ft) Cerro de la Mona. The island is about 1.5 kilometres in length from northeast to southwest, and 640 metres across at its widest.Additional Site Details

Short-term variability of fish larvae assemblages in Malpelo island, an isolated oceanic island in the Eastern Tropical Pacific
A study of Malpelo Island, an isolated oceanic site in the Eastern Tropical Pacific, reveals distinct larval fish assemblages shaped by local hydrographic conditions. The research identified 26 taxonomic units, with insular waters dominated by epipelagic and reef-associated species like Sardinops sagax, while offshore areas were characterized by mesopelagic taxa such as Diogenichthys laternatus. Despite no significant difference in larval abundance between locations, low assemblage similarity (45%) and high species turnover (79%) underscored the island's ecological distinctiveness. Larvae exhibited diel vertical migration, ascending to shallower layers at night, influenced by thermocline and halocline depth. The findings provide critical baseline data for conservation efforts in this UNESCO World Heritage Site.

Discovering the mesophotic fauna of Malpelo Ridge: biodiversity insights in a remote marine sanctuary
A recent study reveals that Malpelo Fauna and Flora Sanctuary harbors significantly higher fish biomass in its mesophotic ecosystems (30-150 m depth) than previously estimated. The research, conducted during the 2025 Mesophotic Scientific Expedition, identified six new fish species for the sanctuary, including olive grouper and misty grouper, suggesting deeper reef-associated habitats support substantial biodiversity. Additionally, the study documented 64 benthic megafaunal taxa and 33 fish taxa using remotely operated vehicle (ROV) surveys and scientific diving, with over 90% of macrobenthic records representing new species for the region. The dataset, compliant with international standards, provides baseline information on mesophotic biodiversity in the Colombian Pacific, contributing to global repositories like OBIS and GBIF.

Primer registro de Psammocora cf. stellata (Scleractinia: Psammocoridae)en el Santuario de Fauna y Flora Malpelo, Pacífico colombiano
Researchers document the first record of the coral genus Psammocora in the Malpelo Fauna and Flora Sanctuary, a UNESCO World Heritage Site off Colombia's Pacific coast. The discovery, identified as Psammocora cf. stellata, was made during a scientific dive at 22 meters depth near 'Cueva del Francés' on July 5, 2025. The identification relied on morphological features—nodular colony growth and distinct star-shaped corallites—observed in photographs, aligning closely with Psammocora stellata but lacking physical samples for confirmation. This finding expands the known coral diversity of Malpelo, contributing to the inventory of scleractinian corals in the Colombian Pacific. The study highlights the sanctuary's ecological significance and underscores the importance of visual documentation in marine biodiversity research.

Relative abundance and diversity of sharks and predatory fishes across Marine Protected Areas of the Tropical Eastern Pacific
Marine Protected Areas (MPAs) in the Tropical Eastern Pacific (TEP) play a pivotal role as critical refuges for sharks and large predatory fishes, with oceanic island MPAs supporting some of the highest relative abundances reported globally. This study, using stereo-Baited Remote Underwater Video systems (stereo-BRUVs), found that oceanic island MPAs exhibit significantly greater species richness and fish abundances compared to coastal MPAs, which show signs of depletion due to fishing pressure. The research highlights the importance of MPA remoteness and protection in sustaining marine biodiversity but also underscores the need for improved conservation measures, such as stronger enforcement, to mitigate ongoing threats like 'fishing down the food web' observed in coastal regions.

Description of a Highly Modified Endemic Ground Beetle (Coleoptera, Carabidae) from the Oceanic Island of Malpelo, Colombia
Researchers have identified Dyscolus (Cacothrix) malpelensis, a highly modified endemic ground beetle from Malpelo Island, Colombia—a UNESCO World Heritage Site renowned for its extreme environmental conditions. This new species exhibits unique adaptations, such as tight coaptation of its elytra and pronotum, likely evolved in response to predation pressures from lizards and land crabs, as well as the island's lack of deep soil. The study describes these morphological traits, suggesting they may represent a specialized strategy for survival in Malpelo's harsh, depauperate ecosystem. The findings highlight the resilience and evolutionary ingenuity of invertebrates in extreme oceanic environments.

Microbial shifts associated to ENSO-derived thermal anomalies reveal coral acclimation at holobiont level
Research at Malpelo Fauna and Flora Sanctuary reveals that the microbiome of the sea fan Pacifigorgia cairnsi undergoes significant shifts during El Niño Southern Oscillation (ENSO)-derived thermal anomalies, suggesting coral acclimation to both warming and cooling phases. The study found that microbial community composition and functional profiles differed between extreme temperature phases (warming or cooling) and neutral conditions, with core members like Endozoicomonas and Mycoplasma driving these changes. These shifts indicate a potential mechanism for maintaining coral viability under thermal stress, acting as an extended phenotype that facilitates holobiont acclimation in unperturbed ecosystems like Malpelo, which lacks direct coastal anthropogenic impacts.

Richness distribution patterns of marine elasmobranchs in Colombia
A study on marine elasmobranchs in Colombia reveals significant regional variation in species richness, with the Caribbean coast showing higher diversity compared to the Pacific. The analysis documented 138 species, including 76 sharks and 62 batoids, with 20 species common to both coasts. Notably, the Pacific islands of Gorgona and Malpelo exhibited the highest richness per spatial unit, though completeness estimates suggest ongoing gaps in inventory. Richness estimators indicated that current documentation is incomplete, highlighting the need for further exploration. These findings underscore the importance of targeted conservation efforts, particularly within marine protected areas like the Malpelo Fauna and Flora Sanctuary, to safeguard this ecologically vital group.
