Common year-round in the shallow waters around the Galápagos archipelago, often spotted cruising lagoons and reef flats in small groups. Wikipedia | iNaturalist

Whitetip Reef Shark (Triaenodon obesus) One of the few shark species that can lie motionless on the bottom, pumping water over its gills instead of needing to swim to breathe. A year-round resident of the Galápagos archipelago, commonly found resting in caves and on sandy patches during the day before hunting reef fish at night. Wikipedia | iNaturalist
