A diverse array of marine life is active in the lagoon. A Blacktip Reef Shark swims gracefully from right to left across the foreground, while a Bat Ray glides along the sandy bottom on the left. Several smaller fish, including a dark-colored triggerfish, navigate around the artificial reef structures.

An underwater view of the Shark Lagoon shows a Bat Ray gliding gracefully through the lower-left corner of the frame. Nearby, a Zebra Shark remains stationary, resting on the sandy bottom. Several smaller fish swim among the coral formations as bright sunbeams filter down through the water, creating a dynamic play of light and shadow across the exhibit.

In the underwater environment of the lagoon, a Bat Ray is seen gliding gracefully across the sandy floor. A male California Sheephead, easily identified by its striking red and black coloration, swims around the artificial coral structures. Other smaller fish are visible in the background, and a shark-like fish is seen resting on the bottom behind the center reef.

A Bat Ray glides gracefully over the sandy bottom of the lagoon, using its pectoral fins to propel itself. Above it, a Zebra Shark with a characteristically long tail swims through the water column, while smaller, unidentified fish dart near the artificial reef structures.
Jun 1, 2026
A Blacktip Reef Shark swims prominently across the foreground, passing close enough to the camera to reveal its characteristic black-tipped fins. In the background, a Bat Ray rests quietly on the sandy floor of the lagoon while several smaller reef fish dart among the coral and artificial reef structures.

In the quiet nighttime waters of the lagoon, a large Zebra Shark rests motionlessly on the sandy floor, its long tail stretched out behind it. A Blacktip Reef Shark swims gracefully across the frame, its dark fin tips cutting through the water. On the left side of the scene, a ray is partially visible, remaining still on the substrate.
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.
