    Starfleet is a weird and wonderful dive, and definitely one of our favourite spots on the Caribbean side. It’s not about dramatic walls or huge pelagics, but rather an intense focus on the smaller stuff, the things you might swim right past elsewhere. We're talking about finding Lamellose Wentletraps on sponges, or watching fleets of Reef Silversides shimmering like liquid mercury. The bottom is often silty, which means you need to be mindful of your buoyancy, but that substrate is exactly why you find things like Dentate Lucines digging in the sand or Reticulated Brittle Stars draped across a rock. We really love the sheer density of grunt species here – Sailor's Choice, Spanish Grunts, you name it, they’re everywhere. Keep an eye out for the Dark Green Parrotfish, their colours are stunning against the Mustard Hill Coral. It's a site that rewards slow diving and a keen eye; definitely bring a macro lens if you’re into photography. Starfleet is perfect for divers who appreciate the subtle beauty of the reef's smaller inhabitants, offering a different kind of thrill than the Pacific's big animal encounters.
