If you dive with us, these are the sharks you have a realistic chance of seeing.
Silky Shark (Carcharhinus falciformis). Galápagos Shark (Carcharhinus galapagensis), the species named for these islands. Blacktip Shark (Carcharhinus limbatus). Tiger Shark (Galeocerdo cuvier). Galápagos Bullhead Shark (Heterodontus quoyi), a small bottom-dwelling species, nothing like the pelagics. Whale Shark (Rhincodon typus), IUCN Red List Endangered, and the focus of the research we fund. Scalloped Hammerhead (Sphyrna lewini), the schooling species of Wolf and Darwin. Whitetip Reef Shark (Triaenodon obesus).
The remaining twenty-six species recorded in the archipelago are rare, occasional, migratory or pelagic — real, but not what a week of diving is planned around.
We will not promise you any given animal on any given dive. What the season, the site and the currents make likely is a different claim from a guarantee, and we keep those separate.
