"An increase in the number of whale-watching tours in southern Costa Rica’s Ballena National Marine Park has prompted officials from the National System of Conservation Areas (SINAC) to increase monitoring and regulation in the area.
A large number of tourist boats could threaten the presence of whales, dolphins, stingrays and sharks in the park, located near Uvita on the Pacific coast, environment officials said. Biologists consider the protected area a perfect location between the northern and southern hemispheres for the birth of new generations of marine mammals and other species.
On their arrival, whales enter into a trance, and any abrupt change to their natural habitat could cause them to migrate to other areas with less suitable conditions for giving birth to calves – a direct threat to their species, biologists say."
