Brown boobies are commonly seen in Costa Rica’s Pacific marine environments, especially around Cocos Island, the Gulf of Dulce, and Isla del Caño, where nutrient-rich waters support thriving fish populations. They often travel in small flocks and can be observed gliding low over the waves or perched on offshore rocks and cliffs.

These seabirds play a key ecological role in marine food webs, acting as indicators of ocean health. Their presence often signals areas rich in marine life, and they are frequently seen during dolphin or whale watching tours.

With their graceful hunting tactics and striking appearance, brown boobies are yet another reminder of Costa Rica’s remarkable biodiversity that extends far beyond the rainforest—out into the open sea where sky and water meet.

This incredible image captures a spinner dolphin (Stenella longirostris) mid-air, showcasing its famous acrobatic leap and spin above the ocean surface. These dolphins are named for their extraordinary ability to spin multiple times while leaping, a behavior thought to play a role in communication, mating displays, or simply fun social interaction.

Spinner dolphins are frequently spotted in the Pacific waters of Costa Rica, especially around marine protected areas such as Isla del Coco, the Golfo Dulce, and Bahía Drake. These regions are vital feeding and resting grounds for large pods, which can number in the hundreds or even thousands.

In the Costa Rican marine ecosystem, spinner dolphins are key top predators, feeding primarily on small fish and squid. Their activity helps regulate prey populations and supports the balance of the pelagic food web.

The spinner dolphin (*Stenella longirostris*) is a small delphinid species renowned for its acrobatic surface behavior, particularly its characteristic spinning leaps, which can involve multiple rotations along the longitudinal axis. These behaviors are thought to serve social, communicative, or possibly parasite-removal functions, although the exact purpose remains a subject of scientific investigation.

Spinner dolphins are pantropical, with distinct populations across the Atlantic, Indian, and Pacific Oceans. In Costa Rica, particularly along the Pacific coast, they are frequently observed in nearshore and offshore waters, often associated with diurnal foraging-resting cycles. During daylight hours, they aggregate in large, tight-knit pods in shallow bays or coastal areas to rest, while at night they disperse into deeper waters to forage, mainly targeting mesopelagic prey such as lanternfish (Myctophidae) and squid, which ascend toward the surface after dusk.

Morphologically, S. longirostris is characterized by a long, slender rostrum, a tripartite color pattern (dark dorsal cape, light gray flanks, and white ventrum), and highly streamlined body adapted for agile swimming and burst-speed maneuvers. Adults typically range from 1.5 to 2.1 meters in length and weigh up to 80 kg.

Taxonomically, the species includes several geographically and morphologically distinct subspecies or forms, such as the eastern, central, and dwarf forms, some of which may warrant full species status pending further genetic analysis.

In Costa Rican waters, the resident spinner dolphin populations are vulnerable to anthropogenic pressures, including bycatch in tuna purse-seine fisheries, vessel traffic, and increasing marine tourism. However, Costa Rica's marine protected areas and ecotourism regulations have helped mitigate some of these threats.

Did You Know?

Despite their size and bulk, Baird’s tapirs are excellent swimmers, often using rivers to travel or escape predators like jaguars. They are mostly nocturnal and solitary, making sightings like this one truly special.

This remarkable image captures a caravan of leafcutter ants—some of the rainforest’s most fascinating and industrious inhabitants—carrying bits of leaves back to their underground colony. These ants, commonly seen across Costa Rica’s tropical forests, are part of the genus Atta or Acromyrmex, and are renowned for their complex social organization and ecological importance.

Although they appear to be harvesting leaves for food, leafcutter ants actually use the leaves to cultivate a special fungus, which is their primary food source. Inside their vast subterranean nests, they chew the leaf fragments into a pulp, where the fungus grows in carefully tended chambers. This relationship, called mutualistic farming, is one of the most sophisticated examples of non-human agriculture on Earth.

Leafcutter ants are ecosystem engineers—their foraging can impact vegetation patterns, their tunnels aerate the soil, and their presence contributes to nutrient cycling. Each colony can contain millions of individuals, working together in castes that include workers, soldiers, and a queen.

In Costa Rica’s biodiverse rainforests, these ants symbolize the cooperation, balance, and intricate connections that sustain life in the jungle. Watching them in action is like seeing the inner workings of nature’s great machine—silent, precise, and incredibly powerful in its unity.

This captivating image shows two tent-making bats (*Uroderma bilobatum*) nestled beneath the protective shelter of a carefully modified leaf—a natural umbrella they created themselves. Commonly found in Costa Rica’s lowland rainforests, these bats are named for their remarkable behavior of chewing through large leaves (often from banana or palm plants) to create hanging “tents” that shield them from predators, rain, and the tropical sun.

These small, fruit-eating bats play a vital role in the ecosystem as pollinators and seed dispersers, contributing to forest regeneration and the maintenance of biodiversity. Their diet consists largely of figs and other native fruits, and their ability to travel long distances helps spread seeds across wide areas of rainforest.

This image captures the intense gaze of an American crocodile (*Crocodylus acutus*) gliding stealthily through the murky waters of a Costa Rican mangrove. With only its eyes and ridged back breaking the water’s surface, this apex predator perfectly embodies the quiet power and mystery of the country’s coastal ecosystems.

Costa Rica’s Pacific and Caribbean coasts are home to extensive mangrove forests—rich, biodiverse habitats where crocodiles thrive. These reptiles play a crucial role as top predators, helping to regulate populations of fish, birds, and smaller reptiles, and maintain ecological balance in estuarine environments.

The American crocodile is not aggressive by nature, but is highly territorial and incredibly well-adapted to brackish environments. Their presence is a powerful indicator of a healthy ecosystem, as they rely on clean waters and abundant prey.

Mangroves like these are among the most productive ecosystems on Earth, acting as natural nurseries for marine life, filtering pollutants, storing carbon, and protecting coastlines from erosion. Spotting a crocodile in the wild is a thrilling reminder of how wild and untamed Costa Rica remains—where jungle meets sea, and ancient predators still reign.

This species, though once threatened, is now protected in Costa Rica, with populations recovering thanks to the country’s strong conservation efforts. It’s another reason why Costa Rica is a global model for biodiversity and sustainable ecotourism.
