The sea anemone fauna of Isla del Coco National Park (also known as Cocos Island Nacional Park), Pacific Costa Rica is poorly known. In the present work we report the first occurrence of the species Telmatactis panamensis. Individuals of this sea anemone (n=24) were collected at Chatham Bay intertidal and at 15m depth in Punta Ulloa, in both cases attached to rocks; during the expedition UCR-UNA-COCO-I in April 2010. We provide photographs of live individuals, external anatomy and an inventory of cnidae of the studied specimens. Possibly this species is extended to greater depth as observed by other authors in the Galápagos Islands. Citation: Acuña, F.H., J. Cortés & A. Garese. 2012.

AbstractAlthough the killing of giant tortoises in the Galapagos Islands has been prohibited since 1933, poaching of tortoises still occurs. Personnel of the Galapagos National Park Service and the Charles Darwin Research Station regularly survey populations of tortoises throughout the archipelago and report all dead tortoises found. For the 10-year period 1995–2004 the field personnel reported evidence of 190 giant tortoises killed, primarily on the southern portion of Isabela Island. For the first 6 years the number of tortoises found killed was <15 per year, but since 2001 the number killed has increased dramatically, with 49 tortoises poached in 2004. During the same 10 years the number of tortoises found dead from natural causes was 131. Many of these deaths can be attributed to events associated with the 1997–1998 El Niño or with outbreaks of disease on Santa Cruz Island in 1996 and 1999. The results indicate that poaching exceeds natural mortality, and is a significant factor affecting these long-lived and slow-reproducing animals. Environmental education efforts in the human population of southern Isabela appear to have had little effect. Because tortoise poaching takes place at a small number of sites, effective enforcement at those sites could reduce killing of tortoises.

The Galápagos Islands, long acknowledged as Darwin’s “Living Laboratory,” are one of the world’s most important ecological treasures. From their discovery in 1535 until the creation of the Galápagos National Park in 1959, human hands touched lightly on their shores. Seemingly incapable of sustaining colonization because of poor soil, a scarcity of water, and no mineral wealth, the absence of humans allowed the native species of the Galápagos to remain undisturbed until whalers in the 1790s found that the lumbering Galápagos tortoises could be stored for months in their ship’s holds as a source of fresh meat. In 1832 Ecuador took possession of the archipelago but its colonization efforts generally failed. Although human settlement remained minimal, mammals that people brought (goats, donkeys, pigs, dogs, and cats) flourished and diminished the numbers of the endemic species. When the Galápagos National Park opened, only about 2,000 people lived on the islands along with the remaining endemic species and hundreds of thousands of feral animals. Meanwhile, naturalist Charles Darwin’s remarkable 1859 study, On the Origins of Species had stimulated biologists’ interest in the islands’ wildlife by presenting overwhelming proof of evolution. Other biologists questioned his idea of natural selection as the mechanism behind evolution; consequently they gathered evidence from collected specimens and observations in the archipelago, and finally resolved the debate in Darwin’s favor. After 1990, popular interest in the islands’ wildlife heightened as a result of photography, travelers’ accounts, and films, so tourism increased as did the number of Ecuadorian immigrants eager to earn money in the tourist industry. By 2020, Ecuadorian authorities faced the dilemma of balancing the need to preserve the unique species and their fragile environment against the revenue generated by visitors, a battle environmentalists fear the government is losing.
