As you navigate through its complex terrain, you’ll be enthralled by the sight of magnificent coral formations, including sprawling black corals and vibrant sponges. 

The marine life here is just as mesmerizing.

Add to this the colorful parrot fish nibbling at the corals, and the occasional elusive moray eel peeking out from its crevice. 

USS Kittiwake

Anchored off the shores of Seven Mile Beach in Grand Cayman Island lies the illustrious USS Kittiwake, a former US Navy Submarine Rescue Ship. Purposefully sunk in 2011, this 251-foot vessel now rests as an artificial reef, inviting divers to traverse its five decks and immerse in maritime history. As you explore the ship’s chambers, from the engine rooms to the captain’s quarters, you’ll witness how nature has claimed this steel giant.

Marine Wildlife to Look Out For

When visiting Grand Cayman’s best dive sights, it’s fun to know what marine life you’re looking for to make the most out of your underwater adventure. Here is a list of some of the best underwater creatures you can expect to encounter on your dives. 

Stingray Grand Cayman Island

Southern Stingrays: Southern Stingrays are flat-bodied, diamond-shaped creatures known for their smooth texture and long, whip-like tails. Revered for their elegance and gentle nature, these rays glide effortlessly through the ocean, often skimming the sandy seabed in search of food. On Grand Cayman Island, the most iconic spot to encounter these magnificent beings is at Stingray City. Located in the shallow waters of the North Sound, Stingray City offers visitors an unparalleled opportunity to interact with and even feed these friendly rays.

Barracudas: Barracudas have elongated bodies and razor-sharp teeth, and are often the silent observers of the ocean depths. Their reflective silver scales and piercing gaze make them both fascinating and menacing looking. While they may appear intimidating, barracudas are generally curious and harmless to divers. In the waters around Grand Cayman Island, these sleek predators can be spotted in various dive sites, especially around coral reefs and shipwrecks, where they often hover motionless, watching the world around them. 

Green Sea Turtle Grand Cayman

Turtles: On Grand Cayman Island, the most commonly spotted turtle species are the Green sea turtles and the Hawksbill turtles. These gentle reptiles can often be seen casually gliding near coral reefs or grazing on seagrass beds. Besides wild encounters, the Cayman Turtle Centre in West Bay offers visitors an opportunity to learn about turtle conservation and even interact with these magnificent creatures up close.

Nurse Sharks: Nurse sharks, with their broad heads and calm demeanor, are a delight to spot in the waters of Grand Cayman Island. These docile sharks often rest on sandy bottoms especially in areas with abundant marine life where they seek their prey (mostly small fish and crustaceans). While their size might be daunting, nurse sharks are generally harmless and are a special sight for divers fortunate enough to witness them in their natural habitat.

Moray Eels: Moray eels, with their elongated bodies and distinctive jaws, are intriguing inhabitants of Grand Cayman’s underwater world. Often hiding in crevices and holes of coral reefs, they peek out with curious eyes.

Fun fact;

Although they appear green, moray eels have brownish or grey skin that mixes with a layer of yellow mucus—causing a green hue to appear.

Squid and Octopus: Squid and octopuses are mesmerizing inhabitants of Grand Cayman’s marine world. With their ability to change colors and textures in the blink of an eye, they are masters of camouflage. While they can be elusive, keen-eyed divers might spot them, especially during night dives. 

An Abundance of Fish: ​​When plunging into the crystalline waters of Grand Cayman Island, divers are greeted by a colorful and dynamic array of fish. Tarpons, with their silver scales reflecting the sunlight, are often spotted around Eden Rock and Devil’s Grotto, swimming majestically amidst dense schools of shimmering Silversides that dance in and out of caverns. 

The vibrant hues of parrotfish can be seen nibbling on coral reefs, their beak-like mouths making distinctive scraping sounds as they graze. Additionally, the waters boast an array of other marine wonders, from the elegant butterfly fish darting around corals to the unique Red LionFish.
