PBS's "Spy in the Ocean, a Nature Miniseries" captures a massive gathering of spinner dolphins in the Pacific Ocean near Costa Rica, where they hunt flying fish. The video shows one of the largest known assemblies of these dolphins, numbering in the thousands, and extending deep underwater.
This extraordinary event was documented using spy cameras on animatronic animals for PBS. Among the spinner dolphins, a "spy dolphin" was deployed, offering a unique perspective on their acrobatic leaps out of the water.
Using Robots To Spy Massive Megapod of Spinner Dolphins
Capturing the megapod sequence was a formidable challenge, according to Matthew Gordon, a wildlife producer involved in the project. He revealed the immense difficulty in locating the elusive spinner dolphins, leading to days of extensive sea travel, covering hundreds of kilometers without success. However, when the team finally encountered the dolphins, the true magic unfolded.
Upon locating the pod, the team deployed a "spy dolphin" into the midst of the dolphins and utilized an animatronic bird drone to observe the group from the aerial perspective. This allowed them to closely monitor the dolphins and capture their behavior from multiple angles.
The video footage displays the spinner dolphins' intricate communication, involving clicks and whistles. It became evident that the dolphins used these signals to gather other members of their species from different regions of the ocean, showcasing their ability to coordinate and collaborate.
The megapod was not confined to the surface alone, as Gordon noted that it extended deep underwater as far as the eye could see, even in relatively clear water. At its peak, the pod contained several thousand dolphins, creating a breathtaking spectacle.
The "Spy in the Ocean" series relies on lifelike robotic technology to avoid disrupting the natural behavior of the animals, as traditional cameras might. Placing the "Spy Dolphin" at the heart of the action provided a unique perspective, offering viewers a glimpse into what it would be like to be a part of the pod, swimming alongside real tuna and dolphins.

Spinner Dolphins Characteristics
Spinner dolphins are highly agile and playful marine creatures known for their acrobatic displays. They frequently leap out of the water and perform intricate aerial maneuvers, including impressive spins that can reach heights of nearly 10 feet.
These behaviors serve multiple purposes, from shedding irritating remoras to communicating within their pods. Biologists believe that the spins and leaps convey messages like "Let's go," "Danger," or even expressions of attraction. Alongside these physical displays, spinner dolphins communicate using whistles, echolocation clicks, and other vocalizations.
Found in large pods that can consist of a few dozen to over a thousand individuals, spinner dolphins thrive in tropical and subtropical regions worldwide, with the Indian Ocean being a particularly abundant habitat.
They are nocturnal hunters, preying on small fish, squid, and shrimp during the night in the open ocean. During daytime, they return to shallower waters for rest and social interaction. Spinner dolphins typically reach sexual maturity at around eight years of age.
Fully grown spinner dolphins are relatively small, measuring between 129 and 235 cm in length and weighing between 23 and 79 kg. Their reproductive cycle involves a gestation period of approximately 10 months, and mothers nurse their young for one to two years before the offspring become independent.
