Schools of hammerheads are a signature Socorro sighting, most consistently reported around Roca Partida and Cabo Pearce. They typically stay at the edge of visibility in open water rather than approaching closely.

The marquee species. Schools are seen over seamounts and at cleaning stations across the year; sources agree the largest aggregations, sometimes 100 to 500+ individuals, form in the late rainy season, roughly August to October. IUCN lists the species as Critically Endangered.

Schools are present year-round at Wolf, Darwin, Gordon Rocks and Kicker Rock. Sources genuinely conflict on the densest months — warm-season (calmer, clearer) versus cool-season upwelling — so this is coded reliable year-round rather than a single peak.

Hammerheads are reported occasionally at Manta Bowl and in Ticao Pass but are far from reliable — treat as a rare bonus, not a target. Requires the offshore dive.
