Isabela Island by the Sierra Negra volcano, one group in the east and another over the western and southwestern slopes. At least one authority has suggested merging C. n. vicina with C. n. microphyes, C. n. vandenburghi and C. n. guentheri as the southern Isabela tortoise (C. n. vicina), putting morphological differences down to geographic ...
Chelonoidis niger vicina, commonly known as the Cerro Azul giant tortoise, Iguana Cove tortoise or the Isabela Island giant tortoise, is a subspecies of Galápagos tortoise endemic to Isabela Island in the Galápagos. [1]
The tortoise's range is limited to an area of 476 km 2 (184 sq mi) on the Alcedo Volcano on the central part of Isabela Island. There it inhabits deciduous and evergreen forests as well as humid grassland .
In 2024, the Galápagos National Park Directorate and the Galápagos Conservancy successfully rehabilitated 136 Galápagos tortoises on the Island of Isabela. The young tortoises between the ages of 5 and 9 years old were reared in the Arnaldo Tupiza Breeding and Rearing Center on Isabela and transported by helicopter to another area of the ...
The Volcán Wolf giant tortoise (Chelonoidis niger becki), also known commonly as the Wolf Volcano giant tortoise [1] and the Cape Berkeley giant tortoise, is a subspecies of Galápagos tortoise in the family Testudinidae. The subspecies is native to the north side of Ecuador's Isabela Island (formerly Albemarle Island).
The tortoise's range is limited to an area of about 800 km 2 on the slopes of the Sierra Negra volcano, from near sea-level to an altitude of around 1,000 m, at the southern end of Isabela Island. There it inhabits deciduous and evergreen forests, dry grassland, introduced vegetation and agricultural land. The population is estimated to ...
Isabela is home to more wild tortoises than all the other islands. Isabela's large size and notable topography created barriers for the slow-moving tortoises; apparently the creatures were unable to cross lava flows and other obstacles, causing several different sub-species of tortoise to develop.
