Estrecho del Infiernillo, Marine strait between Tiburon Island and Sonora, Mexico.
The Infiernillo Strait extends for 70 kilometers with varying widths between 3 and 5 kilometers, reaching its narrowest point at 1.6 kilometers.
Spanish explorer Francisco de Ulloa discovered the strait in 1539 during the colonization period of the Gulf of California region.
The Seri people refer to the strait as Xepe Coosot, meaning narrow sea, and Xepe Heeque, translating to small sea in their native language.
Strong currents during high and low tides affect navigation conditions through the strait, requiring careful planning for maritime activities.
The strait contains 81 endemic invertebrate species from the Gulf of California and serves as a protected Ramsar site covering 27,900 hectares.
