A diverse array of marine life is active in this underwater lagoon. A Zebra Shark rests peacefully on the sandy bottom in the foreground near a coral structure, while another swims past. A Leopard Shark and several Bat Rays glide through the water in the background, navigating around the rockwork and artificial reef elements.

In the low light of the lagoon, a Zebra Shark is seen resting on the sandy bottom before beginning to swim, showing off its exceptionally long tail. A Bat Ray glides through the water on the right side of the frame, while several Leopard Sharks and other fish are active in the background and near the central rock formations.

A Zebra Shark is seen resting quietly on the sandy bottom in the foreground, displaying its distinctive spotted pattern. A large Bat Ray swims across the frame, passing very close to the camera lens with its rhythmic flapping motion. In the background, a Leopard Shark and several other fish are visible, either resting on the substrate or swimming through the lagoon environment.

A Green Sea Turtle swims across the sandy floor of the lagoon, passing by a decorative rock and coral formation in the center. A Zebra Shark is seen resting on the sand in the lower-right foreground, while a Bat Ray glides through the water on the right side of the frame. Several smaller fish are also visible swimming near the central reef structure.

In this underwater scene, a Blacktip Reef Shark swims through the upper water column. On the sandy bottom, a Leopard Shark rests quietly near a Green Sea Turtle, which is tucked under a central coral formation. A Bat Ray glides along the left edge of the frame, and several smaller fish swim throughout the lagoon.
Geographic range
Where Does the Bat Ray Live?
The Bat Ray is a signature species of the Eastern Pacific Ocean, native to the coastal waters of North America. Its primary range stretches from the temperate shores of Oregon in the United States, down through the entire length of California, and extending into the warm waters of the Gulf of California in Mexico. They are particularly common in protected inland bays and lagoons, where the shallow, nutrient-rich waters provide ideal nurseries for their young.

Behavior
Bat Rays are highly graceful swimmers that appear to 'fly' through the water by flapping their massive, wing-like pectoral fins. Unlike many of their stingray relatives that spend most of their time buried in the sand, Bat Rays are frequently observed cruising through the mid-water column or soaring near the surface of bays and kelp forests. They are social animals and are often found in large schools, sometimes numbering in the hundreds, particularly during the summer mating season.
When it comes to feeding, these rays are the 'excavators' of the seafloor. They use their pectoral fins to flap against the sediment, creating a suction that uncovers buried prey like clams and shrimp. They possess incredibly strong, flat teeth arranged in plates—much like a conveyor belt—that allow them to crush the hardest shells with ease. While they possess a venomous stinger for self-defense, they are generally shy and will choose flight over fight when encountering humans.

Camera Tips
Capturing the Bat Ray on an EverydayEarth setup requires a shift to underwater or dock-side monitoring. If you live on a coastal property or have access to a pier, the most effective method is to mount a waterproof action camera or a dedicated submersible camera to a piling or a weighted tripod. Position the camera about 1 to 3 feet off the bottom, aimed toward sandy clearings or the edges of eelgrass beds, as these are the primary 'flight paths' rays use when foraging for food.
Lighting is the biggest challenge for aquatic wildlife. In shallow water during the day, natural sunlight is usually sufficient, but a polarized filter on your lens is a game-changer if you are filming from above the surface, as it cuts through the water's reflection. For nighttime captures, avoid using a powerful, direct spotlight which can scare the rays; instead, use a wide-angle, diffused red light or a low-intensity LED to capture their nocturnal foraging without causing a flight response.
While you cannot use traditional bait like birdseed, you can attract Bat Rays by placing a perforated PVC pipe filled with crushed mussels or clams near your camera. The scent trail will draw them into the frame to investigate. Set your camera to a high frame rate, such as 60fps, to capture the hypnotic, undulating motion of their wings. This slow-motion footage is particularly effective for AI identification and for observing the unique way they use their snouts to probe the sand.
