Marisla Seamount, also known as "El Bajo", is located about 8 miles (13 km) NNE of La Paz, Mexico. There are three underwater peaks arrayed three hundred yards, 120°-300°; the northernmost to 83 ft (25 m) of the surface, the central peak to 52 ft (16 m), and the southern to 69 ft (21 m).

This is a site for schooling hammerhead sharks (Sphyrna lewini), with large schools at the base of the sea mount. Schools range from between six to hundreds traveling in a clockwise direction around the seamount. As a seamount El Bajo is home to an abundance of sea life, mass schooling fish (amberjacks, tuna etc), octopus (O. hubbsorum) and Panamic green moray eel (Gymnothorax castaneus); a colony can be found in a small submarine canyon. Other visitors that frequent the seamount include; whale sharks and giant Pacific manta rays (Manta hamiltoni). Marisla Seamount was named after dive cruise ship Marisla II(Mexican Flag), formerly USCG Cutter Columbine, owned by Maria Luisa Adcock and Richard M. Adcock. Richard was the first known sport diver, using SCUBA gear, to dive on the Seamount in 1957. Adcock continued making commercial sport diving cruises to the sea mount utilizing Marisla (a converted LCM 56) and continued the dive business with Marisla II commencing in 1968 through 2009. Marisla and Marisla II both have been scrapped.
