What is "caracolero"

Caracolero (1971 – after 1987) was a Kentucky-bred, French-trained Thoroughbred racehorse and sire. He showed some promise as a two-year-old in 1973, winning one of his three races, but was rated well behind the best of his year in France. In the following year he won the Prix Barneveldt and the Prix Matchem before establishing himself as one of the best European colts of his generation with an upset win in the Prix du Jockey-Club. He was injured in his only subsequent race and was retired to stud, where he had little success as a sire of winners.
