Costa Rica is home to an abundance of rare and unique creatures, both on land and in the sea. This relatively small country in Central America contains 12 main ecosystems and hundreds of thousands of species of animals, including mammals, birds, reptiles, amphibians, insects, and fish. While there are plenty of animals that are rather common, there are quite a few that are considered incredibly rare to see.

Oncille, “little spotted cat”

The oncille, or the caucel in Spanish, is one of the rarest animals in Costa Rica. This tiny jungle cat can be found in the lowland forests, premontane forests, and sometimes in the cloud forests that are above 3,000 meters. This cat is as small as a domestic cat and is sometimes even mistaken for one. They are nocturnal and incredibly elusive. Your best chance of spotting one is on a guided night walk in the Corcovado National Park.

Another elusive creature that roams the primary and secondary rainforests and dry forests of Costa Rica is the ocelot. Aptly named manigordo in Spanish for its “fat paws,” this jungle cat is rarely seen. Ocelot populations have taken a major hit due to the illegal fur and pet trade, as well as habitat destruction. They hunt during the night and sleep up in the trees during the day. Your best chance of catching a glimpse of one of these spotted beauties is in the Santa Rosa National Park, Monteverde Cloud Forest Reserve, La Selva Biological Station, or the Corcovado National Park.

The jaguar is an iconic animal in Costa Rica. This large feline tends to live close to water and can be found from Northern Mexico all the way down to Argentina. The jaguar is a highly endangered cat and seeing one in the wild is an experience few people will ever have. While poaching used to be a major threat to the jaguar, now the biggest threat is deforestation. Your chances of seeing one are very slim, but are increased when you explore the Santa Rosa National Park, Hitoy-Cerere Biological Reserve, Santa Elena Cloud Forest Reserve, and Tortuguero National Park.

The tapir, or danta danta, is a bizarre herbivore that can be found in the dry deciduous forests and evergreen forests of Costa Rica. These giant mammals can weight up to 300 kilos. They used to be common in Costa Rica, but are now considered endangered. The Santa Rose National Park and Corcovado National Park have the largest population of tapirs, but spotting them is still a rarity.

Titi monkey

The titi, or squirrel monkey, is Costa Rica’s smallest and rarest monkey. This adorable little primate is found in the tropical evergreen forests, mangroves, and secondary forests of the southern Pacific region of Costa Rica and into Panama. They always travel in troops, which can range from a few to up to 100. Great efforts are being made in Costa Rica to protect these tiny tree creatures. They can be spotted in the Manuel Antonio National Park and Corcovado National Park, as well as sometimes in Penas Blancas National Park and a few others.

Resplendent quetzal

The resplendent quetzal is often referred to as “the emerald jewel of the cloud forest.” This magnificent bird is most definitely on a birdwatcher’s short list. Spotting one is tricky because they blend so well into the lush verdant cloud forests. The breeding season, which is between mid-February through May, is the best time to see them. They prefer to nest in wild avocado trees and are most commonly seen in the cloud forests of Monteverde, the Queztales National Park, San Gerardo de Dota, and Braulio Carrillo National Park.

Jabiru stork

The jabiru stork is called el galán sin ventura in Costa Rica, which translate to ‘the hapless suitor.’ It is believed that there are only around 90 jabiru storks left in the wild in Costa Rica. They only live in one place in Costa Rica—the basin of the Tempisque River. Destruction of habitat is the main culprit for the staggeringly low numbers of this stately stork. A guided boat trip through the Palo Verde National Park is your best chance of spotting the jabiru stork in its natural environment.

Glass frog

The glass frog, or rana de vidrio, is a true marvel. This tiny and partly translucent frog is common in Costa Rica, but rarely seen because of its highly effective camouflage. The glass frog looks very similar to the famous Kermit the Frog. They can be found in the Tortuguero National Park and La Selva Biological Station. There are actually 13 species of glass frogs in Costa Rica.

Whale shark

While whale sharks may be the biggest fish in the sea, they are one of the most docile. The whale shark can grow up to 12 meters (40 feet) long and it survives solely on plankton. They prefer warm tropical waters. They once thrived in most tropical waters around the world, but their numbers have been rapidly decreasing due to the shark fin trade and unsustainable and harmful fishing practices. Encountering a whale shark in the wild is a chance of a lifetime, but one that can happen when diving or snorkeling in Costa Rica.
