Costa Rica, a small Central American nation roughly the size of Scotland, is estimated to house around 5% of the world's animal and plant species, many of them found nowhere else. The country is especially well-known for its prolific and highly visible bird life, and for large marine fauna including hammerhead sharks that gather around the offshore Cocos Islands. The country is well-represented in less iconic wildlife groups. For instance, there are around 400 species of amphibians and reptiles. The country's diversity in so many wildlife groups has been attributed to its position between the major biogeographic realms of North and South America; on land, species from both continental faunas are represented, while at sea the wildlife of both the Pacific and Atlantic oceans can be found in Costa Rican waters.

 

Costa Rica has long been hailed as a conservationist's paradise. It contains one of the most extensive and best-managed protected area networks in the world, and one of the world's best-known ecological research facilities at La Selva. At the same time, timber extraction remains a major threat in the highly diverse southern region of the country, and has been calculated that Costa Rica's reserve system has only reduced deforestation by around 10% since the 1960s, when the first national park was established. Monteverde was at one time renowned for its biodiversity; since the 1980s this site has become a symbol of both the amphibian decline crisis and loss of biodiversity more generally: mammals, reptiles and insects are also more scarce on the mountain than they used to be. This decline has been blamed in part on a rising cloud layer that has resulted in less moisture reaching the forest floor, and this has been attributed to both strong El Nino events and ongoing climate change. It has, however, been argued that a better-understood and potentially more easily remedied factor is to blame: disruption to the water cycle caused by the destruction of unprotected lowland rainforest below the mountain.

 

CRUSTACEANS

 

Costa Rica has over 110 species of marine decapod (crabs, shrimps and lobsters), making them among the country's major marine animal groups. On land, Halloween crabs (Gecarcinus quadratus) (pictured) are commonly encountered in lowland forest on the Pacific coast. These crabs are an important influence structuring coastal forest ecosystems through their role as seed predators, resulting in a gradient of forest types that provide habitats for a wide variety of other wildlife.

ARACHNIDS

 

 

Costa Rica has several notable species of tarantula, among them the red-kneed tarantula (Brachypelma smithi) familiar from pet shops. More than 1,800 species of arachnid are known from the country as a whole, including potentially undescribed members of the black widow family (Theridiidae).

INSECTS

 

 

In total, some 34,000 described species of insect are known from Costa Rica, with many undescribed forms known. There are about 1,250 species of butterfly in Costa Rica, a little less than twice the number in the continental United States, among them several large, electric blue Morpho species. The Hercules beetle (Dynastes hercules), said to be the world's heaviest insect, and several species of both leafcutter and legionnaire (army) ants are also among the nation's charismatic insect inhabitants. Over 8,000 species of moths are known from the country, and it is also home to the world's largest living odonate, the damselfly Megaloprepus caeruleata, which has a wingspan of 191 mm and a body length of 120 mm.

AMPHIBIANS

 

Costa Rica boasts a well-studied, large amphibian fauna of over 170 species, more than 40 of them endemic to the country.. The country rang early alarm bells following reports that several formerly abundant species of amphibians had disappeared from Monteverde National Park in the early 1990s. It has since been discovered that amphibian populations are declining catastrophically worldwide, but the loss of over 20 species from Monteverde in the space of a few years remains one of the most extreme examples of this trend. Known only from Monteverde, the golden toad (Incilius, formerly Bufo, periglenes) is thought to be extinct, having not been seen for almost twenty years. This species had become a national icon following its discovery in 1966; several other missing species have been rediscovered in other locations.

REPTILES

 

There are over 200 species of reptile in Costa Rica, ranging in size from the American crocodile (Crocodylus acutus) to species of anole (small lizards of trees, shrubs and modified habitats). The country's coast forms part of an internationally important series of marine turtle nesting beaches, and the country's first national park was created to protect this habitat. Lizards are a common sight throughout the country; ctenosaurs (Ctenosaura simlis) frequent tourist resorts and even take scraps of food that diners drop. Basilisks, famous for the male's large crests and their habit of running on water, can be abundant (three of the world's four species occur in Costa Rica), and whiptails with brightly-coloured flanks and limbs (genus Ameiva) are often active among  forest leaf litter.

MAMMALS

 

Costa Rica has about 200 species of mammal, a little less than 5% of the world total. Prior to human occupation, this total would likely have been somewhat higher, and is in any case surprisingly high when taking into account the Neotropical zone's relatively depauperate marine mammal fauna. Jaguars and tapirs may still persist in relatively large numbers in some of the country's larger reserves. Although Costa Rica lacks other large land mammals, there are numerous species of smaller cat, 100 species of bat, two of sloth, and three native monkeys, the black howler, white-faced capuchin and woolly spider monkey. A fourth, the squirrel monkey, is a relatively recent introduction from Brazil and has a more restricted distribution in the country.

BIRDS

 

 With 830 species, more than the entirety of continental North America north of Mexico, Costa Rica has a strong claim to possess the most diverse bird fauna of any similarly-sized country in the world. These include many colourful and charismatic species; one of the largest populations of scarlet macaws (Ara macao) in Central America, the rare great green macaw (Ara ambiguus), several species of toucan, numerous hummingbirds and, most famously, the bright turquoise-and-red resplendent quetzal (Pharomacrus moccino), largest member of the trogon family whose feathers were once prized as a mark of status among indigenous populations through much of Central America.
