Massive Dolphin Pod Spotted Off California Coast

Over 1,500 Risso's dolphins amaze whale watchers with rare spectacle.

On the morning of January 30, 2025, off the coast of Carmel Bay, California, a spectacular sight unfolded: over 1,500 Risso's dolphins gathered, creating what is being called a 'super pod.' Captain Evan Brodsky, associated with the Monterey Bay Whale Watch, spotted this astonishing congregation during a routine outing aimed at observing gray whales.

Brodsky described his reaction to the breathtaking display, saying, "It was amazing. I kept saying, 'Look at my screen. Look at my screen. Look how many there are.' My mind was blown each time I surveyed the horizon." He and his team, including marine biologist Colleen Talty, were momentarily taken aback by the sheer number of dolphins frolicking across the waves.

The dolphin pod seemed to be engaging joyfully, leaping out of the water, which Talty noted looked like they were having “a big party, socializing with each other.” According to her expertise, such massive gatherings of dolphins, consisting of both adults and juveniles, likely stem from multiple smaller pods merging as they migrate south.

Throughout the outing, the small team aboard their 20-foot inflatable boat witnessed astonishing behaviors from the dolphins. They saw the dolphins breaching, spy-hopping, and tail-slapping, captivating the observers. The dolphins even swam alongside the boat, utilizing the waves to propel themselves forward, known as bow riding—a fascinating technique common among cetaceans.

Risso's dolphins prefer to inhabit deep offshore waters where they can reach depths of at least 1,000 feet and can hold their breath for approximately 30 minutes. These dolphins typically live and travel alone or within small groups of 10 to 30 animals, according to the National Oceanic and Atmospheric Administration (NOAA). The significant number spotted this day is not only rare but also astonishing, particularly along the Monterey coastline, known for its underwater submarine canyons, which allow these marine animals to venture closer to shore.

The Monterey Bay Whale Watch team, conducting surveys every day, had been hopeful for such sightings but emphasized the uniqueness of this experience. Brodsky remarked later, "It was a really memorable encounter..." reflecting the impact of witnessing such behavior firsthand.

While Risso's dolphins, also referred to as gray dolphins due to their color, are often seen off the California coastline, super pods on this scale remain uncommon. Brodsky's enthusiasm was palpable as he discussed sharing the video footage captured during their excursion. He stated his intent to encourage people to appreciate marine life responsibly, highlighting the importance of observing these majestic creatures adhering to their natural habitats rather than opting for experiences at marine parks.

Overall, the experience served as both inspiration and education, with Talty and Brodsky emphasizing the significance of studying marine wildlife and advocating for conservation efforts. They hope such breathtaking moments draw attention to marine ecology and the need for respect and protection of these creatures.

This sighting is not just another day at sea; it captures the allure of oceanic wildlife and the joy of discovery, bringing about awareness of our natural world and the treasures it holds beneath the waves.

Brodsky concluded, urging, "I want to inspire someone to come to see these animals in the wild where they belong, instead of buying a ticket to a captive marine park." The breathtaking display of over 1,500 Risso's dolphins is emblematic of the rich biodiversity found along the California coast, urging increased efforts toward marine conservation and appreciation.
