Nahuelito

Like Nessie, the Loch Ness Monster, the Argentine creature is named after the lake it supposedly resides in and has been described as a giant serpent or a huge hump, as well as a plesiosaur.

In 1897, Dr. Clemente Onelli, director of the Buenos Aires Zoo, began to receive sporadic reports about a possible strange creature inhabiting the Patagonian lakes.

But Garret's sighting in 1910 was only made public in 1922, when he recounted it to the Toronto Globe newspaper and echoed in the international press, thus motivating himself to organize the first expedition to search for Nahuelito.

In 1960, the Argentine Navy was said to have chased an unidentified underwater object in the lake for 18 days, without being able to identify it, which some people related to this alleged creature.
