The Pacific degu (Octodon pacificus), also known as the Mocha Island degu, a species of rodent in the family Octodontidae, is endemic to Mocha Island. The waters off the island are a popular place for recreational sea fishing.
Geology edit
Geologically, the island is made of sedimentary rock stratum of Ranquil Formation, a formation whose main outcrops lie in the continent.[1] The island was permanently uplifted as result of the 2010 Chile earthquake but this uplift was less than in the adjacent coast where Tirúa had the largest uplift of all the coast.[2] The existence of a splay fault called Tirúa-Mocha Fault may explain the different behaviour of Mocha Island relative to the mainland during this earthquake.[2]
History edit
The island was historically inhabited by an indigenous coastal population of Mapuches known as the Lafkenches. The first European to document Mocha was Juan Bautista Pastene on September 10, 1544, who named it Isla de San Nicolas de Tolentino.
According to Juan Ignacio Molina, the Dutch captain Joris van Spilbergen observed the use of chilihueques (a South American camelid) by native Mapuches of Mocha Island as plough animals in 1614.[3]
Mocha Island was regularly visited by pirates and privateers from the Netherlands and England. Francis Drake and Olivier van Noort are known to have used the island as a supply base. When Drake was visiting it during his circumnavigation of the globe he was seriously hurt by its Mapuche inhabitants. Richard Hawkins, Drake's cousin, also passed with his ship the Dainty. In 1685, the Mapuche were transported by Governor José de Garro to a reducción on the plain on the right bank of the Bio Bio River called the Valley of Mocha that later became the location of the modern city of Concepción, Chile.
The waters off the island were inhabited by sperm whale, including Mocha Dick, who was depicted by American explorer and author Jeremiah N. Reynolds in his published account, "Mocha Dick: Or The White Whale of the Pacific: A Leaf from a Manuscript Journal" in May, 1839 in The Knickerbocker magazine in New York.[4] Mocha Dick was one of the inspirations for the fictional whale Moby Dick in the 1851 novel Moby-Dick by Herman Melville.[5]
Polynesian contact edit
In December 2007 several human skulls with Polynesian features, such as a pentagonal shape when viewed from behind, were found lying on a shelf in a museum in Concepción. These skulls originated from Mocha Island.[6]
