Yikes, that was unexpected 😱
A deep-sea anglerfish patiently waits...
These fish typically use a modified dorsal fin ray that acts as a fishing rod with a glowing lure (bioluminescent bait) to attract prey close by.
The fish can swallow prey up to twice its own size.

The Barred Hamlet is the reef's shy show-off! 🎭 This striking fish is a simultaneous hermaphrodite. When mating, pairs perform elegant dances at dusk, taking turns releasing eggs & sperm. A true marvel!

Your Christmas gift came early… and it’s another Friday Fun Fact!
The Sheepshead fish has a mouth full of human-like teeth, including molars! 😁 These chompers crush crabs & scrape barnacles off pilings. They're so clever, they're famously difficult for anglers to hook.

The Yellow Garden Eel is a shy, mesmerizing sight! 🌾 These slender eels live in colonies, swaying in the current as they feed. Approach too fast and they'll vanish into the sand in a synchronized retreat. Pure underwater magic.

Master the current! 🌊 Drift diving lets you fly underwater, but safety is key. Always deploy an SMB, master your buoyancy, and stay close to your buddy. Go with the flow, not against it!
