Bajo del Monstruo
Depth is the range from the top of the site to its usual maximum; "recommended cert" is the mainstream-agency level operators usually ask for, not a legal rule. Currents and visibility change daily — treat everything here as planning ranges.
The Monster's Shoal is named for what lives below it: smalltooth sand tigers (Odontaspis ferox), a deep-water shark divers essentially never meet, which researchers and a lucky handful of very deep divers have documented at Malpelo. Encounters happen well below recreational limits and are rare events even for the prepared - this atlas records the site's fame without promising the shark. At diveable depths the bank still justifies the trip out: hammerheads and Galapagos sharks working a cold, current-swept plateau at the edge of visibility. It is a dive for disciplined teams with deep training, redundant gas, and modest expectations - and it is unforgettable when the monster shows.
The moment you come for: The chance, never the promise, of Odontaspis ferox; deep-bank hammerhead traffic

Know before you splash
Hazards: Depth, cold, current, and remoteness stacked together - the most serious dive in this destination.
