Everyday at Nicuesa we are grateful for being living in such a wonderful paradise. Just by being in the Osa Peninsula and Golfo Dulce, you can tell that you are in a very special place. The breathtaking scenery of the Osa Region is more than enough to feel Mother Earth’s power.
But… What is it about this place that makes it so extraordinary?
|Rio Esquinas Mangrove|
Osa region of Costa Rica is a true biological treasure. It is the healthiest
primary rainforest on the whole pacific coast in Central America. In this
entire region it is the forest that contains the tallest trees and supports
some of the biggest populations of endangered fauna. There is an exceptionally
high number of endemic species, meaning that they occur only in this place in
ACOSA, or the Osa Conservation Area, there is a cluster of protected areas, 17
in total, including the Corcovado National Park and Piedras Blancas National
Park. This patch of protected area represents only 3% of the country’s
territory, but is home to half of the Costarican plant and animal species. That
is an extremely high level of density of species, considering that Costa Rica
contains 4% of the world’s biodiversity.
factors. A very wide variety of ecosystems can be found here, due to
variability in conditions of elevation, rainfall, temperature and morphology of
territory. There is abundant rain (5-6 meters per year) and sunlight, and like
the rest of the country, it is the very bridge between North America and South
America, thus it harbors flora and fauna from both land masses.
|Playa Nicuesa’s view to Golfo Dulce|
“Golfo Dulce” (literally, “Sweet Gulf”) is the marine equivalent of the lush,
pristine jungles in the area. Commonly called a gulf, it is actually a fjord,
one of the only four tropical fjords in the world. With a maximum depth of 700
feet, it contains very different habitats that range from warm, shallow marine coral
formations where little fish abound, to the cold depths that only cetaceans can
Cetacea comprises whales, dolphins and porpoises. Surprisingly, their closest
terrestrial relatives are ungulate mammals, which include horses, cows, tapirs
and deer among others. It was a long evolutionary way to adjust a terrestrial
mammal for life in the ocean. Some of the most obvious adaptations are the
transformation of hind limbs into a flattened tail, the fusing of cervical
vertebrae that allows no neck movement whatsoever, and the shift from front
nostrils to blowholes at the upper part of the head.
marine mammals, cetaceans and manatees are the only ones that spend their whole
life in the ocean. These are truly amazing animals, it is a very remarkable
fact that terrestrial mammals evolved to go back into the ocean, from which
their ancestors had emerged many millions of years ago.

two suborders within the Cetacea order, Mysticeti and Odontoceti. Mysticeti, or
baleen whales (also called toothless whales) have mouth plates instead of teeth
and have two blowholes. All members of the Odontoceti suborder (which includes
all dolphins and toothed whales) have teeth and only one blowhole.
the waters that surround the Osa region, biologists have reported as much as 23
species of cetaceans, including the Sperm Whale, Orcas, Bryde’s whale, and
several species of dolphins. Among
the more commonly seen cetaceans around the Golfo Dulce, are the spinner
dolphins, spotted dolphins, bottle nose dolphins. All these are resident and
can be seen year round. Humpback whales on the other hand, seasonally come to
breed and nurse the calves. Populations from the south arrive from August
through November, and populations from the north arrive from November through
June. This overlap in breeding seasons makes the Golfo Dulce an extremely rare
spot where different populations meet, promoting genetic variety of this
