From ScubaDiving.com; The Captiva Blue Hole (popularlyand misleadinglyknown as the Crack) has a circular opening that starts at 85 feet, while the sink bottoms out at 180. Approximately 32 miles southwest of Boca Grande, the ancient blue hole features numerous undercuts in the shaft’s limestone walls, harboring everything from octopus to regal sea goddess nudibranchs to spiny oysters. And since Florida’s gulf waters are always teeming with outsized creatures, don’t be surprised if a dive into the Captiva Blue Hole reveals a giant loggerhead turtle napping under a ledge.
